Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If metal blocks are used for resistance in conventional strength training equipment, then the equipment provides stable muscle strength training, but the load weight cannot be adjusted immediately and is difficult to fine-tune according to training situations
Solution Approach 1:
The patent replaces the traditional mechanical weight block system with an electric resistance system. A resistance motor connected to a controller can dynamically adjust the resistance force applied to the cable, enabling immediate and precise load adjustment without physically changing weight components. This substitution of mechanical weight adjustment with electrical control resolves the contradiction between ease of operation and device complexity.
Solution Approach 2:
The patent changes the resistance parameter from fixed physical weights to dynamically controllable electrical resistance. The controller can modify the resistance motor's output in real-time based on training requirements, allowing continuous fine-tuning of load weight. This parameter change enables rapid adaptation to different training situations without the inertia of physical weight changes.
2Adaptability or versatility
If fixed weight metal blocks are used, then the equipment structure is simple, but the training mode becomes too standardized and cannot enhance explosive force
Solution Approach 1:
The patent introduces dynamic resistance control through the resistance motor and controller system. Unlike static weight blocks, the electrical resistance system can continuously vary the resistance level during exercise execution, enabling adaptive training modes that respond to athlete performance in real-time. This dynamics capability supports explosive force training by allowing rapid resistance modulation throughout the range of motion.
Solution Approach 2:
The patent creates a universal resistance control system that can support multiple training objectives within a single equipment platform. By replacing specialized weight blocks with a programmable resistance motor, the equipment can be configured for different training modes (strength, endurance, explosive power) through software control rather than hardware changes, achieving multi-functionality without proportionally increasing structural complexity.
3Productivity
If multiple metal blocks are added or removed to adjust weight, then different load levels can be achieved, but the process is time-consuming and cannot be done immediately
Solution Approach 1:
The patent replaces the manual mechanical process of adding/removing weight blocks with an automated electrical control system. The resistance motor, controlled electronically, can instantaneously adjust resistance levels through electrical signals, eliminating the time-consuming physical manipulation of weight components. This substitution dramatically improves training efficiency by enabling immediate load transitions between exercises or sets.
