Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sensors are disposed on the surface of the controller device to detect finger motion, then finger motion detection is enabled, but detection accuracy deteriorates due to variations in user hand size
Solution Approach 1:
The sensor support section enables dynamic adjustment of sensor positions along the longitudinal direction. The support structure includes a movable sensor module that can be repositioned to different locations on the controller body, allowing the sensor array to adapt its configuration based on the user's hand size. This dynamic repositioning capability ensures that sensors maintain optimal alignment with finger joints regardless of whether the user has small or large hands, thereby preserving detection accuracy across different user populations.
Solution Approach 2:
The invention changes the spatial parameters of the sensor system by providing adjustable inter-sensor distances and variable positions relative to the controller main body. The sensor support section allows modification of key parameters including the distance between adjacent sensors and the overall position of the sensor array, enabling the system to optimize its geometric configuration for different hand sizes and thereby maintain reliable detection accuracy.
2Measurement precision
If sensors are fixed at specific positions to match users with large hands, then detection is improved for those users, but detection accuracy deteriorates for users with small hands
Solution Approach 1:
The sensor support section transforms the fixed sensor arrangement into a dynamic, adjustable configuration. Users can reposition the sensor module along the longitudinal axis of the controller to accommodate their specific hand size. This dynamic adjustment capability ensures that both users with large hands and users with small hands can achieve optimal sensor-finger alignment, thereby maintaining high measurement precision across the full range of user hand sizes.
Solution Approach 2:
The adjustable sensor support structure provides universal adaptability to accommodate diverse user populations. By enabling position adjustment of the sensor array, the system becomes multi-functional in terms of its spatial configuration, serving both users with large hands and users with small hands effectively. This universal design approach eliminates the need for multiple fixed configurations and allows a single device to maintain high detection precision for all users.
3Device complexity
If the distance between adjacent sensors is fixed, then device structure is simplified, but adaptability to different hand sizes is reduced
Solution Approach 1:
The sensor support section introduces a dynamic adjustment mechanism that allows the distance between adjacent sensors to be modified. The support structure includes movable components that enable users to change the spacing configuration according to their hand size requirements. This dynamic capability adds moderate structural complexity but provides significant benefits in terms of adaptability, allowing the device to accommodate various hand sizes while maintaining reasonable structural simplicity through modular design.
