Nivaar worked solution (AI-drafted; not reviewed by a licensed engineer)
National Exams, May 2016 — 07-Mec-B5 Product Design and Development. Three hours. Open book; no calculator is permitted. Question 1 must be completed and is worth 40 marks; four of the six remaining questions are chosen, each worth 15 marks, for 100 marks in total. Only the first five questions as they appear in the answer book are marked. The paper states that most questions require an answer in essay format or the use of tables, figures and charts, and that clarity and organisation of the answer are important.
The paper prints 40 + 6 × 15 = 130 marks and a candidate attempts 40 + 4 × 15 = 100 of them. All seven questions are answered below, because this set is a study resource rather than an examination script. The marking scheme printed on the last source page splits Question 1 as 9 / 9 / 4 / 9 / 9 and gives the part weights for every 15-mark question; the answers here are proportioned to that split. Because no calculator is permitted, every calculation is arranged so that it can be carried out on paper in one or two lines — ratios of round numbers, never a logarithm that has to be evaluated.

A visitor walking a production floor sees, in half an hour and without any effort to extract it, a great deal of what the company knows: the process route, the tooling, the fixtures, the cycle times, the yields on the boards by the line, the products on the rack that have not been announced, the customers named on the shipping cartons, and the equipment vendors. An NDA is the instrument that converts that exposure from an uncontrolled disclosure into a controlled one. Five reasons, roughly in order of legal weight:
1. To preserve trade-secret status, which confidentiality alone creates. A trade secret has no registration and no certificate; its entire legal existence depends on the information being secret and on the holder having taken reasonable steps to keep it so. Disclosure to a person under no obligation of confidence can destroy the secret outright, and — equally important — it undermines the “reasonable steps” element on which any later claim rests. The NDA, together with visitor logs, badges, escorting and photography restrictions, is the reasonable step, and its evidentiary value is as great as its contractual value.
2. To avoid a public disclosure that destroys patent novelty. Patentability requires novelty, and a disclosure that makes an invention available to the public before filing can defeat it. Canada is comparatively forgiving: under the Patent Act an applicant has a twelve-month grace period for disclosures originating from the applicant. Most other jurisdictions are not — the European Patent Office and China apply absolute novelty — so a single unprotected factory tour can extinguish foreign rights on an invention that remains patentable at home. Since Canada moved to a first-to-file system in 1989, the date of filing rather than the date of invention governs, which makes an early uncontrolled disclosure doubly dangerous. A disclosure made under an NDA is not a public disclosure, so the NDA preserves the option to file.
3. To create a defined obligation and a practical remedy. Without an agreement, a company must fall back on the general law of confidence and prove that the information was confidential, that it was communicated in circumstances importing an obligation, and that it was misused. The NDA settles the first two in advance, defines precisely what is covered and for how long, and typically adds specific remedies — injunctive relief, return or destruction of materials, agreed jurisdiction — that make enforcement fast enough to matter.
4. To fix ownership and use of anything arising from the visit. A well-drafted visitor NDA does more than prohibit disclosure. It restricts use as well as disclosure, so the visitor may not build a competing process from what they saw; it addresses ownership of any improvement or idea discussed during the visit, which otherwise becomes a genuine dispute; and it commonly includes a residuals clause, a no-reverse-engineering clause and a bar on photography and recording.
5. To discharge obligations owed to third parties, and to set the tone. Much of what is visible on a factory floor is not the company’s own secret but its customers’ — parts under a customer NDA, drawings, packaging bearing a customer’s brand — and the company is contractually obliged to protect it. There may also be export-control or personal-information obligations. Finally, the act of signing performs a function of its own: it tells the visitor that the site is confidential, which changes behaviour more reliably than a clause ever does.
Two practical qualifications are worth a mark. An NDA is not a substitute for physical control — sensitive areas should still be curtained or off the tour route, because an agreement is a remedy after the fact and a wall is a control before it. And an NDA is only as good as the counterparty’s solvency and the practicality of suing them, so for the highest-value processes the right answer is not to show them at all.
The five principal options in the Canadian frame, administered by the Canadian Intellectual Property Office (CIPO) except for trade secrets, are set out below. They are complements, not alternatives: a single product routinely carries all five at once.
| Option | What it protects | How it is obtained | Term (Canada) | Strengths / limits |
|---|---|---|---|---|
| Patent | A new, useful and non-obvious invention — a product, composition, machine, process or improvement. Function, not appearance. | Application to CIPO with claims and a full enabling disclosure; examination; must be requested within the prescribed period. First-to-file since 1989. | 20 years from the filing date, subject to maintenance fees | The strongest right — a monopoly enforceable even against an independent inventor. But it is expensive, slow, national in scope, and it publishes the invention: the bargain is disclosure in exchange for a limited monopoly. A 12-month grace period applies to the applicant’s own disclosure in Canada, but not in absolute-novelty jurisdictions. |
| Industrial design registration | The visual features of shape, configuration, pattern or ornament of a finished article — appearance, explicitly not function. | Registration with CIPO under the Industrial Design Act; a formalities-led examination; must be filed within 12 months of the design being made public by the applicant. | The later of 15 years from filing and 10 years from registration | Cheap and fast relative to a patent, and it is the right tool for a product whose value is in its look — a bottle silhouette, a handle profile. It protects nothing functional, and it is easy to design around by changing the appearance. |
| Trade secret | Any commercially valuable information kept secret — formulations, process parameters, tooling know-how, customer lists, yields, source code. | No registration. Protected by contract (NDAs, employment terms) and by the common law of confidence, or the Civil Code in Quebec, provided reasonable steps are taken. | Indefinite — until the secret is out | Costs nothing to obtain, has no term limit, and requires no disclosure — the classic case is a formulation kept secret for a century. But it gives no protection against independent discovery or lawful reverse engineering, and it is destroyed permanently the moment it leaks. Suits anything not detectable in the sold product. |
| Trade mark | A word, design, sound or shape that distinguishes one trader’s goods or services from another’s — brand and source, not technology. | Rights arise from use; registration with CIPO under the Trade-marks Act gives nationwide rights and a much stronger enforcement position. | 10 years from registration, renewable indefinitely while in use | The only right that can last forever, and the one that captures accumulated goodwill. It protects nothing about how the product works, and it is lost if the mark is not used or becomes generic. |
| Copyright | The expression of an original work — drawings, software, firmware, manuals, marketing material, databases. Not the idea, and not a functional article. | Automatic on creation and fixation; registration with CIPO is optional and serves as evidence. Canada is a Berne signatory, so protection is essentially worldwide. | Life of the author plus 70 years (extended from plus 50 in 2022) | Free, automatic and long. But it protects only expression, so a competitor may re-implement the same function in different code or redraw the same part; and section 64 of the Copyright Act limits copyright in the design of a useful article once more than fifty copies are made, which is precisely why industrial design registration exists. |
The engineering point behind the table is the selection logic, and it is where the marks in a strong answer lie. Ask whether the innovation is visible in the sold product: if a competitor can find it by buying one and taking it apart, a trade secret is worthless and a patent is the only real option; if it is a process parameter locked inside the plant, a trade secret is often better than a patent because it never expires and never publishes. Ask where the value sits: in function (patent), in appearance (industrial design), in brand (trade mark), in written or coded expression (copyright). Ask what the budget and the product life will bear, since a patent family across major markets is a five- or six-figure commitment and a four-year consumer product may not repay it. And then layer them: the mechanism is patented, the housing shape registered as an industrial design, the firmware and manuals under copyright, the name a registered trade mark, and the process settings and supplier terms held as trade secrets under NDA — which is exactly the situation Part A protects.
