Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a dedicated game system is used for communication, then communication reliability is improved, but device complexity and location restrictions increase
Solution Approach 1:
The training instrument incorporates a universal communication portion that can communicate with multiple types of devices (portable terminals, game systems, servers) using standard communication protocols, eliminating the need for dedicated communication systems and reducing overall system complexity while maintaining reliable communication
2Reliability
If a dedicated game system is required, then communication stability is improved, but adaptability and accessibility deteriorate
Solution Approach 1:
The communication portion is designed to work with multiple device types including portable terminals, game systems, and servers, allowing the training instrument to be used in diverse settings without requiring dedicated systems, thereby improving both adaptability and maintaining communication stability
Solution Approach 2:
The communication portion acts as an intermediary that translates and transmits data between the training instrument and various external devices using standardized protocols, enabling stable communication across different device types without requiring device-specific communication systems
3Measurement precision
If load detection is implemented, then training feedback is improved, but device complexity increases
Solution Approach 1:
The patent replaces complex mechanical measurement systems with electronic load detection sensors that provide precise load measurement while reducing mechanical complexity. The load detection portion uses electronic sensing elements that convert mechanical load into electrical signals for processing
4Adaptability or versatility
If wireless communication is added, then accessibility and mobility are improved, but energy consumption increases
Solution Approach 1:
The communication portion transmits load detection data periodically or on-demand rather than continuously, reducing energy consumption while maintaining wireless connectivity and accessibility. The system can adjust transmission frequency based on training intensity and user needs

AI summary
A training instrument 10 comprises a hollow main body 12 formed of an aluminum alloy. The main body is constituted by two gripping portions 12a opposite to each other with a space therebetween and a coupling portion 12b coupling the two gripping portions. A load sensor 16 is arranged in the coupling portion inside the main body. The load sensor is a load cell, a strain gauge affixed to an interior of the main body, and a part of the main body to which the strain gauge is affixed functions as a strain body. Therefore, if a user applies a force so as to bring the two gripping portions close to each other or a force so as to move the two gripping portions away from each other, a load thereof is detected by the load sensor.
