Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the hand retainer is made secure and adjustable, then hand retention is improved, but device complexity increases
Solution Approach 1:
The hand retainer incorporates an adjustable mechanism that allows dynamic adaptation to different hand sizes and gripping preferences. The retainer can be repositioned along the controller body, transforming a static structure into a dynamic one that adapts to user needs, thereby improving reliability without permanently increasing complexity.
Solution Approach 2:
The hand retainer design allows modification of key parameters such as position, tension, and angle to optimize hand retention. By enabling parameter adjustment rather than fixing the structure, the system achieves improved reliability while maintaining design flexibility that prevents excessive complexity.
2Measurement precision
If sensors are positioned to minimize shadowing, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The tracking arc extends beyond the controller body into spatial dimensions that reduce shadowing effects. By positioning sensors in an extended arc rather than directly on the controller surface, the system achieves better measurement precision by utilizing three-dimensional spatial arrangement to minimize occlusion.
Solution Approach 2:
The tracking system is segmented into multiple sensors distributed along an arc rather than a single centralized sensor. This segmentation allows each sensor to capture data from different angles, improving overall tracking precision while distributing the complexity across multiple simpler sensor units rather than one complex arrangement.

AI summary
A controller for an electronic system includes a controller body having a handle portion, a tracking arc that is fixed to the controller body, and a hand retainer configured to physically bias a user's palm against an outside surface of the handle portion. A plurality of tracking sensors is disposed in the tracking arc, and are responsive to electromagnetic radiation emitted by the electronic system. An array of proximity sensors are spatially distributed around the outer surface of the handle portion, and are responsive to a proximity of the user's fingers to the outside surface of the handle portion.
