Detailed design

What is mechanical design?

Mechanical design integrates technology, mechanism design, manufacturing specifications, standards, directives, and environmental constraints. The requirements below are used by research + DESIGN for this phase.

  1. Concurrent strategy:
    Complex projects require multiple teams to operate concurrently, and a management strategy to align dependencies and outputs.
  2. Guidelines:
    Guidelines are informally recognised best practice design recommendations that help inform project development.
  3. Standards:
    Standards are formal and possibly internationally recognised design criteria, which a project may need to conform to.
  4. Directives:
    Directives are official, authoritative, and state governed criteria that a design is required to conform to.
  5. Dependency reduction:
    Reducing connectivity and dependencies between components reduces complexity, failure rates, and the risk of unforeseen knock-on effects.
  6. Moving components:
    Moving components which employ a sliding, rotating, or folding action are positioned as individual mechanism-design projects.
  7. Spurious noises:
    Unforeseen spurious noises that emanate from assemblies and component friction may not be desirable in certain applications.
  8. Tamper detection:
    Tamper detection indicates when a design has been compromised, and tamper proofing attempts to prevent such an intrusion from occurring.
  9. Vandal proofing:
    Vandal proofing aims to manage excessive impact force, defacement, and theft of publicly accessible designs.
  10. Illumination design:
    Illumination design is concerned with the detailed setup and manipulation of lighting in environments and products.
  11. Acoustic design:
    The acoustic design is concerned with the controlled emanation, propagation, and insulation of sound.
  12. Impact resistance:
    Impact resistance is the ability of a design or material to withstand high force and shock over a short period of time.
  13. Drop resistance:
    Drop resistance requires a design to remain functional when dropped during operation, storage, or transport.
  14. Supporting load:
    Supporting load applies to both environment and product, and depending on the application, it covers static and dynamic forces.
  15. Design stability:
    Product stability, also termed topple testing, is a design ability to remain upright when a lateral force is applied.
  16. Electrical insulation:
    Safety compliance may require exposed or accessible electrically charged components or surfaces to be insulated to prevent shock.
  17. Electrostatic Discharge (ESD):
    Certain electronic devices and components are sensitive to static discharge and require shielding.
  18. Object ingress protection:
    A design may need to manage the potential ingress of the following solid objects: hands, tools, wires, or dust.
  19. Water ingress protection:
    A design may need to manage forms of water ingress: falling drops, water sprays, water jets, or immersion in water.
  20. Temperature range:
    Exposing a design to a temperate range or thermal cycle/shock exposes material, component, and mechanism-design weaknesses.
  21. Humidity range:
    Management of humidity within the vicinity of, or within, a design helps prevent corrosion, electrical shortages, and material failure.
  22. Scratch resistance:
    Scratch resistance preventative measures are typically applied to an area of a design, rather than to the design as a whole.
  23. Chemical resistance:
    Certain chemicals can attack material properties, and resistance needs to be designed in. or appropriate warnings provided.
  24. Ultraviolet (UV) resistance:
    Prolonged Ultraviolet (UV) radiation exposure, found in sunlight, can degrade certain material structures and surface finishes.
  25. Radio Frequency (RF):
    Radio Frequency (RF) transparency is considered when a transmitter or receiver is enclosed or shielded.
  26. Design evaluation:
    Apart from physical mock-ups, simulations with a declared Confidence Internal (CI) can be used to iteratively test ideas.
