Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional motorized turntable mechanics are used, then haptic feedback and sophisticated user interaction are achieved, but device complexity, size, and cost increase significantly
Solution Approach 1:
The patent replaces complex mechanical turntable systems with an actuator-based system that directly drives the user interface element. The actuator electronically controls rotation and haptic feedback, eliminating the need for mechanical belts, gears, and complex motor assemblies while maintaining sophisticated interaction capabilities.
Solution Approach 2:
The user interface element serves multiple functions: it acts as both the display surface and the interactive control element, and the actuator provides both rotational movement and haptic feedback generation. This multi-functionality reduces the number of separate components needed in the system.
