Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a folding mechanism is introduced to reduce storage space, then storage convenience is improved, but the complexity of the device increases and stability deteriorates
Solution Approach 1:
The treadmill frame is divided into a fixed frame and a sliding frame that can move relative to each other. The sliding frame includes a sliding component that travels along a guide track, separating the folding function from complex mechanical linkages. This segmentation achieves compact storage while maintaining structural simplicity.
Solution Approach 2:
An electromagnetic lock serves as an intermediary device between the sliding frame and fixed frame. It provides automatic locking and unlocking functions, eliminating the need for manual folding operations and complex mechanical fastening mechanisms, thereby reducing device complexity while ensuring stable connection.
2Volume of moving object
If a folding mechanism is introduced to reduce storage space, then storage convenience is improved, but the stability of the device deteriorates
Solution Approach 1:
The electromagnetic lock acts as a reliable intermediary that provides automatic locking between the sliding frame and fixed frame. It ensures stable connection during operation and automatic engagement during storage, eliminating the stability issues associated with manual folding mechanisms.
Solution Approach 2:
The patent replaces traditional mechanical folding linkages with a sliding frame guided by a guide track and locked by an electromagnetic lock. This substitution eliminates the instability caused by mechanical folding joints while maintaining compact storage capability.
3Volume of moving object
If the running belt is tightened during storage, then storage compactness is improved, but the service life of the running belt decreases
Solution Approach 1:
The tensioning mechanism automatically adjusts the running belt tension during storage and operation. The spring-loaded tensioning roller maintains optimal belt tension without manual intervention, preventing both excessive tightness that would reduce service life and excessive looseness that would compromise storage compactness.
Solution Approach 2:
The tensioning mechanism dynamically adjusts the tension parameter of the running belt based on the operational state. During storage, the belt is maintained at a relaxed but secure tension, while during operation, the tension is automatically increased to optimal levels, preventing premature wear and extending service life.
4Productivity
If a complex folding mechanism is used to achieve compact storage, then storage efficiency is improved, but the ease of operation deteriorates
Solution Approach 1:
The electromagnetic lock provides automatic locking and unlocking functions, eliminating the need for manual folding operations. The sliding frame automatically engages with the guide track and locks into position, making the storage and deployment operations simple and intuitive, thereby improving ease of operation while maintaining high storage efficiency.
