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