Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If spring is used in the lifting system to provide elastic force, then the lifting platform can be operated manually with reasonable price, but the elastic force is variable which makes the operation not smooth and causes unsuitability when weight changes
Solution Approach 1:
The patent changes the lifting force parameter from variable (spring) to constant by introducing a constant force spring mechanism. The constant force spring maintains a steady lifting force regardless of position or weight changes, ensuring smooth and consistent manual operation throughout the lifting range.
Solution Approach 2:
The patent introduces an adjustable constant force mechanism that adapts to different weight conditions. The adjustable structure allows users to modify the constant force output based on the actual load, maintaining optimal lifting performance across varying weights while preserving manual operation smoothness.
2Device complexity
If common lifting platform structure is used, then the device is simple, but parts collide with each other at the end of descending process especially when heavy objects are placed
Solution Approach 1:
The patent applies beforehand cushioning by installing buffer structures at the ends of the lifting platform components. These buffers are positioned in advance to absorb impact forces before collisions occur, preventing damage to parts during the descending process while maintaining overall structural simplicity.
3Reliability
If clamp teeth under table board are used to cooperate with bolt for locking, then locking function is achieved, but the cost is high and it is difficult to use
Solution Approach 1:
The patent inverts the traditional locking approach by using a clamp plate that actively engages with positioning teeth on the movable device, rather than using clamp teeth on the stationary table board. This inversion simplifies the locking mechanism, making it more cost-effective and easier to operate while maintaining reliable height locking.
