Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a hand retainer is added to the controller, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The hand retainer is designed with an adjustable length mechanism that allows dynamic adaptation to different user hand sizes. The retainer can be extended or retracted along the longitudinal axis of the handle, transforming from a static component to a dynamic one that adapts to user needs, thereby improving ease of operation without permanently increasing device complexity.
Solution Approach 2:
The hand retainer's length parameter is made variable through an adjustment mechanism. By changing the length parameter of the retainer, the system can optimize comfort and control for different users. This parameter change capability allows the same device to serve multiple users with different hand dimensions, improving overall ease of operation.
2Measurement precision
If tracking sensors are embedded in the handle, then measurement precision is improved, but device complexity increases
Solution Approach 1:
Multiple sensing functions are merged into a single integrated sensor array embedded in the handle. The sensor array combines proximity sensing and finger motion tracking capabilities, allowing the system to detect both the presence of fingers and their movement trajectories. This merging approach improves measurement precision while avoiding the complexity of separate sensor systems.
Solution Approach 2:
The embedded sensor array serves multiple functions: detecting finger presence, tracking finger motion, and potentially determining grip strength. This multi-functional sensor system improves measurement precision across different interaction modes without requiring separate specialized sensors for each function, thereby managing device complexity.
3Adaptability or versatility
If the hand retainer is made adjustable, then adaptability is improved, but device complexity increases
Solution Approach 1:
The hand retainer incorporates a self-adjusting mechanism that allows users to independently modify the retainer length without requiring tools or assistance. The adjustment mechanism likely uses simple user-actuated components such as sliders, buttons, or magnetic coupling that enable one-handed operation, making the system adaptable to different users while minimizing the complexity of the adjustment mechanism.

AI summary
An electronic controller includes a controller body having a head that adjoins a handle at a neck region, and that includes at least one thumb-operated control. The controller includes a hand retainer that in a closed position is configured to physically bias the user's palm against an outer surface of the handle. The hand retainer includes a resilient member that biases the hand retainer towards an open position. An adjustment mechanism couples the resilient member to the head and permits the resilient member to be adjusted betweena plurality of discrete positions to adjust the resilient member towards or away from the user's purlicue. The adjustment mechanism may include an anchor that is movable peripherally about the head between the plurality of discrete positions and is pivotably attached to the resilient member with a two-part fastener, with a friction member interposed between the resilient member and the anchor.
