Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional hand gripper is used with one handle abutting against the palm and the other handle pressed by four fingers, then the pressing movement training is provided, but the thumb cannot be fully trained and the device cannot measure the force and duration of pressing
Solution Approach 1:
The main body is designed to be pressed by all five fingers including the thumb, making the device universally applicable for training all fingers. The pressure sensor integrates multiple functions: detecting pressing force magnitude, measuring pressing duration, and providing feedback. This multi-functional design resolves the contradiction by enabling both comprehensive finger training and precise measurement capabilities.
Solution Approach 2:
The patent replaces the simple mechanical spring-based resistance system with an electronic measurement and feedback system. The pressure sensor substitutes for basic mechanical feedback by providing precise digital measurement of pressing force and duration, and by enabling electronic feedback mechanisms that guide the user to achieve proper training parameters.
2Reliability
If no measurement system is integrated into the hand gripper, then the device structure remains simple, but the effectiveness of training cannot be ensured
Solution Approach 1:
The patent implements a feedback mechanism where the pressure sensor detects pressing force and duration, the processor analyzes the data, and the feedback device provides real-time guidance to the user. This feedback loop ensures training effectiveness by guiding users to achieve target pressing parameters, resolving the contradiction between reliability and complexity through intelligent control.
Solution Approach 2:
The device performs self-measurement and self-evaluation of training effectiveness. The pressure sensor automatically detects pressing parameters, the processor compares them against target values, and the feedback device provides autonomous guidance without requiring external monitoring equipment or personnel, thereby managing complexity while ensuring reliability.
3Stability of the object's composition
If the pressure sensor is permanently fixed in the main body, then the device structure is more stable, but the sensor cannot be replaced or adjusted
Solution Approach 1:
The patent transitions from a static, permanently fixed sensor arrangement to a dynamic, adjustable configuration. The detachable sensor design allows users to remove and replace sensors based on training needs, while the positioning structure ensures stable installation when mounted. This dynamic approach resolves the contradiction by providing both stability during use and flexibility for adjustment.
