Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a resistance system with elastic cords is added to the carriage, then adjustable resistance is provided, but device complexity increases
Solution Approach 1:
The patent combines the resistance system and range of motion limiting system into a single integrated mechanism. The elastic cords serve dual functions: providing resistance during exercise and limiting the range of motion through the control cord and elastic member assembly. This merging reduces the need for separate independent systems, thereby managing device complexity while achieving adaptability.
Solution Approach 2:
The elastic cords and control cord mechanism serve multiple functions simultaneously. The same elastic member that provides resistance also acts as a range of motion limiter when combined with the control cord. This multi-functionality allows the system to offer adjustable resistance and controlled motion ranges without requiring additional separate mechanisms, thus improving adaptability while controlling complexity.
2Ease of operation
If a range of motion limiting system with control cord and elastic member is added, then controlled motion ranges are provided, but device complexity increases
Solution Approach 1:
The range of motion limiting function is merged with the resistance system. The control cord connects the elastic member to the carriage, creating an integrated mechanism where the same components that provide resistance also control the range of motion. This integration avoids adding separate independent range of motion limiting mechanisms, thereby managing device complexity while achieving controlled motion ranges.
Solution Approach 2:
The control cord acts as an intermediary element that transfers and regulates the elastic force from the elastic member to the carriage. This intermediary mechanism allows smooth and controlled limitation of motion range without requiring complex mechanical stops or constraints, providing ease of operation while maintaining relatively simple device architecture.
3Adaptability or versatility
If elastic cords are selectively attached to the carriage, then customizable resistance is achieved, but ease of operation decreases
Solution Approach 1:
The system employs dynamic attachment mechanisms where the elastic cords can be selectively connected or disconnected from the carriage based on user needs. This dynamic configuration allows customization of resistance levels without requiring complex adjustment procedures, as the elastic cords can be quickly attached or detached to modify the resistance characteristics of the exercise system.
