Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional fixed-length fastener is used, then the structure is simple and easy to manufacture, but it cannot adapt to clearance between components
Solution Approach 1:
The patent applies the dynamics principle by making the lug structure adjustable rather than fixed. The elastic part allows the blocking part to move between different positions, enabling the fastener to adapt to varying clearances between components. This dynamic adjustment capability resolves the contradiction by providing adaptability without requiring a completely complex reconfigurable system.
Solution Approach 2:
The patent changes the positional parameter of the blocking part on the lug to adapt to different clearance conditions. By allowing the blocking part to be positioned at different locations along the lug's length, the fastener can accommodate various component separations. This parameter change approach provides adaptability while maintaining a relatively simple overall structure.
2Adaptability or versatility
If the inlet height is fixed, then the manufacturing is simple, but it cannot accommodate protrusions of different thicknesses
Solution Approach 1:
The inlet height is made dynamic through the movable blocking part on the elastic lug. As the blocking part moves to different positions, the effective inlet height changes, allowing accommodation of protrusions with different thicknesses. This dynamic adjustment maintains manufacturing simplicity by using a single elastic component that can assume multiple positions rather than requiring multiple fixed-height components.
Solution Approach 2:
The elastic part automatically adjusts the blocking part's position based on the thickness of the protrusion being inserted. The elastic deformation provides self-adjustment capability, eliminating the need for complex adjustment mechanisms or precise pre-setting of inlet heights for different applications.
3Adaptability or versatility
If the fastener structure is made adjustable to adapt to clearance, then the adaptability improves, but the operation complexity increases
Solution Approach 1:
The elastic lug with movable blocking part provides self-adjusting functionality during insertion. As the protrusion is inserted, the elastic part automatically deforms and positions the blocking part at the appropriate location, eliminating the need for manual adjustment operations. This self-service mechanism maintains operation simplicity while achieving clearance adaptation.
Solution Approach 2:
The blocking part's position parameter changes automatically during the insertion process based on the protrusion thickness. This automatic parameter change eliminates complex manual adjustment operations while still providing adaptability to different clearances and protrusion dimensions.
4Adaptability or versatility
If the blocking part is made fixed, then the structure is stable and simple, but the inlet height cannot be adjusted
Solution Approach 1:
The blocking part is made dynamic by allowing it to move along the elastic lug. This movement capability provides inlet height adjustability without requiring a completely complex reconfigurable structure. The elastic lug itself serves as the adjustment mechanism, maintaining relative structural simplicity while achieving the desired adaptability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The assembly effectively adapts to clearance between components, providing secure support between panels while being easy to operate and manufacture, with low costs and reliable connection during use and transportation.
Implementation Method 1
the distal end of the elastic part is configured to be movable relative to the distal end of the blocking part under the drive of an external force
Implementation Method 2
When the distal end of the elastic part is in a free state, the protrusion having entered the receiving channel is held in the receiving channel by means of the distal end of the elastic part

AI summary
A nut fastener assembly includes a nut assembly and a fastening clip. Opposite sides of the bottom of the nut assembly are provided with a pair of protrusions. The fastening clip includes a pair of lugs arranged on opposite ends of the fastening clip and extending towards the nut assembly, and a pair of receiving channels configured to respectively penetrate the pair of lugs. At least one of the pair of lugs is an adjustable lug including a blocking part and an elastic part. The distal end of the elastic part is movable relative to the distal end of the blocking part. The corresponding protrusion in the pair of protrusions can enter the corresponding receiving channel through a space between the distal end of the blocking part and the distal end of the elastic part to be held in the receiving channel.
