Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a plurality of actuators are used to provide localized haptic effects, then the haptic feedback capability is improved, but the device complexity increases
Solution Approach 1:
The operation panel is divided into multiple regions, with each region containing a specific actuator. This segmentation allows independent control of haptic feedback in different areas, improving localized feedback capability while managing complexity through modular organization.
Solution Approach 2:
Different actuators are positioned at specific locations (e.g., center, edges, corners) of the operation panel to provide localized haptic effects. Each actuator is strategically placed to influence a particular region, enabling differentiated haptic feedback experiences across the panel surface.
2Measurement precision
If actuators are positioned at specific locations to generate localized vibration, then the haptic effect precision is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The actuators are pre-positioned at predetermined locations (center, edges, corners) during manufacturing. These predetermined positions serve as reference points that simplify the assembly process and reduce the need for high-precision real-time positioning, while still achieving the desired localized haptic effects.
3Stability of the object's composition
If multiple attaching parts are used to secure actuators to the operation panel, then the structural stability is improved, but the device complexity increases
Solution Approach 1:
The attaching parts are integrated into the operation panel structure itself, combining the functions of the panel and the mounting structure. This merging reduces the number of separate components while maintaining stable attachment of actuators at predetermined locations.
