Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a hand retainer is added to secure the user's hand, then hand retention and control stability are improved, but device complexity increases
Solution Approach 1:
The hand retainer is implemented as a separate, adjustable strap component that can be independently adjusted and positioned, rather than integrating it into the main controller body. This segmentation allows the retainer to be optimized for hand security while keeping the controller design modular and manageable.
Solution Approach 2:
The hand retainer incorporates an adjustable length mechanism that allows dynamic adaptation to different user hand sizes and preferences. This adjustability enables the system to maintain optimal hand retention for each user without requiring a completely different design for each hand size.
2Measurement precision
If finger motion sensing is integrated into the controller, then measurement precision of finger motions is improved, but device complexity increases
Solution Approach 1:
Multiple sensing functions (proximity sensing, finger motion sensing, and grip detection) are merged into a single integrated sensor system within the controller body. This consolidation reduces the number of separate components needed while maintaining comprehensive sensing capabilities for precise finger motion tracking.
Solution Approach 2:
The sensor system is designed to perform multiple functions simultaneously - detecting proximity, tracking finger motion, and monitoring grip strength - using a unified sensing architecture. This multi-functionality reduces overall system complexity compared to having separate dedicated sensors for each function.
3Adaptability or versatility
If multiple sensors are embedded in the controller, then functionality and user interaction are enhanced, but manufacturing precision requirements increase
Solution Approach 1:
The sensor system is divided into functionally distinct sensing zones and sensor types positioned at specific locations within the controller body. This segmentation allows each sensor to be positioned and calibrated for its specific function, reducing the overall manufacturing precision requirements compared to a fully integrated sensing system.
4Adaptability or versatility
If the hand retainer is made adjustable, then adaptability to different users is improved, but device complexity increases
Solution Approach 1:
The hand retainer incorporates an adjustable length mechanism that allows dynamic adaptation to different user hand sizes and preferences. This adjustability enables the system to maintain optimal hand retention for each user without requiring a completely different design for each hand size.
Solution Approach 2:
The adjustability is achieved by changing the length parameter of the hand retainer strap through a simple mechanical adjustment mechanism. This allows the same retainer design to accommodate various users by modifying a single geometric parameter (length) rather than requiring different retainer designs for different users.

AI summary
A controller for an electronic system includes a tracking member fixed to a controller body. The controller body has 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. The resilient member is attached to an anchor that is attached to the head by an adjustment mechanism that permits the resilient member to be moved towards or away from the user's purlicue. The tracking member includes transducers that are coupled to the electronic system by electromagnetic radiation. Proximity sensors, spatially distributed on the handle, are responsive to a proximity of the user's fingers to the outer surface of the handle.
