Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If conventional rigid guiding parts are used, then structural strength is maintained, but contact stability with the frame deteriorates and material usage increases
Solution Approach 1:
The patent applies a U-shaped flexible guiding part that can deform to maintain stable contact with the frame. This flexible structure allows the carrier to adapt its shape during movement, ensuring continuous contact with the frame surface while using less material compared to rigid structures that require additional support elements.
Solution Approach 2:
The guiding part transitions from a static rigid structure to a dynamic flexible structure that can change shape during operation. This dynamic adaptation allows the carrier to maintain optimal contact with the frame throughout its movement range, improving stability without requiring excessive material.
2Area of stationary object
If more guiding wheels are added to improve contact, then contact surface increases, but device complexity and maintenance requirements increase
Solution Approach 1:
Instead of adding multiple rigid guiding wheels to increase contact area, the patent uses a single U-shaped flexible guiding part that naturally conforms to the frame surface. This flexible structure provides continuous contact along its length, achieving the same effect as multiple wheels but with simpler construction and lower maintenance requirements.
3Ease of operation
If conventional lifting columns are used, then structural stability is maintained, but ease of operation and adaptability deteriorate
Solution Approach 1:
The patent changes the physical parameters of the guiding part from rigid to flexible, allowing it to adapt to different operating conditions. This flexibility enables easier operation as the carrier can smoothly follow frame imperfections and variations, while the U-shape maintains structural stability through its geometric configuration.
