Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If a synchronous belt structure is used to enable infinite rotation, then the movement range is improved, but the device complexity increases
Solution Approach 1:
The synchronous belt structure serves multiple functions: it transmits rotational motion, enables infinite rotation without displacement constraints, and provides continuous slip simulation. This multi-functionality allows a single component to address movement range limitations while maintaining structural efficiency.
Solution Approach 2:
The synchronous belt acts as an intermediary element between the motor and the simulation interface, transferring rotational motion while enabling continuous, constraint-free rotation. This mediator approach resolves the contradiction by decoupling the motor's rotational capability from the simulation requirements.
2Adaptability or versatility
If multiple synchronous belts are used to provide slide simulation in multiple directions, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The system divides the slip simulation function into multiple independent synchronous belts, each responsible for a specific direction. This segmentation allows each belt to handle a particular directional component, and through coordination, achieve multi-directional simulation capability.
Solution Approach 2:
The patent transitions from single-direction to multi-directional simulation by introducing additional synchronous belts operating in different directions. This dimensional expansion enables the system to simulate slip in multiple directions simultaneously through the coordinated action of belts arranged at different orientations.
3Measurement precision
If a complex slip simulation apparatus is used to provide accurate slip sensation, then the measurement precision is improved, but the ease of manufacture deteriorates
Solution Approach 1:
The patent uses synchronous belts to create a simplified copy of the slip sensation mechanism. Instead of complex mechanical linkages, the system replicates slip effects through the friction and motion characteristics of the synchronous belt, achieving accurate slip simulation with simpler manufacturing requirements.
Solution Approach 2:
The invention replaces complex mechanical slip simulation mechanisms with a more manufacturable synchronous belt system. The synchronous belt's inherent friction characteristics and motion transmission properties are utilized to generate slip sensations, eliminating the need for intricate mechanical assemblies while maintaining simulation accuracy.
