Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an actuator is added to drive the display unit, then tactile feedback capability is improved, but device complexity increases
Solution Approach 1:
The display unit is designed to serve multiple functions: it acts as both the visual display interface and the vibration feedback actuator. The display unit can generate vibrations directly in response to touch inputs, eliminating the need for separate vibration motors or actuators. This multi-functional design provides tactile feedback capability while avoiding the complexity increase that would result from adding dedicated vibration components.
2Measurement precision
If force-sensing units are incorporated to detect user input, then user interaction accuracy is improved, but device complexity increases
Solution Approach 1:
The force-sensing function is merged with the existing display unit structure. The display unit incorporates sensing capabilities that detect user touch and pressure directly at the interaction surface, integrating the sensing function into the display assembly rather than adding separate sensing components. This reduces overall device complexity while maintaining high measurement precision for user input detection.
3Stability of the object's composition
If buffer members are added to mitigate environmental vibrations, then device stability is improved, but device complexity increases
Solution Approach 1:
The buffer members are pre-configured within the housing structure to counteract environmental vibrations before they can affect the display unit. The housing incorporates damping materials and vibration-absorbing features that are built-in from the design stage, providing preliminary protection against vibrations. This approach improves device stability without requiring complex active vibration cancellation systems or additional separate buffer components.
