Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening nuts for panels and accessories lack effective rotational prevention, often relying solely on joining pressure, which can lead to undesirable rotation during tightening, and fail to adapt to varying panel thicknesses.
Innovation Solution
A fastening nut with flexible and resilient spring elements that integrate with a fixing plate, providing anti-rotational security and adaptable fitting through slotted openings, allowing for secure attachment across different panel thicknesses and preventing accidental separation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If joining pressure between legs and panel surface is used to prevent rotation, then the fastening nut can be simple in structure, but rotation prevention is insufficient and undesirable rotation occurs during tightening
Solution Approach 1:
The patent changes the physical state of the fixing elements from rigid to elastic by using spring elements that can deform laterally. This elasticity allows the elements to exert continuous rotational preventing force on the panel while accommodating variations in panel thickness and surface irregularities, thereby improving rotation prevention reliability without significantly increasing structural complexity
Solution Approach 2:
The fixing elements are designed as dynamic spring elements that can laterally deform and adapt to the panel thickness. This dynamic capability allows the elements to maintain optimal contact force with the panel surface during tightening operations, preventing rotation while automatically adjusting to different installation conditions
2Adaptability or versatility
If fixed-length fixing elements are used, then the manufacturing is simple, but the fastening nut cannot adapt to different panel thicknesses
Solution Approach 1:
The patent employs spring elements with elastic properties that allow lateral deformation. This elasticity enables the fixing elements to adapt their effective length and contact position to match different panel thicknesses, providing versatility without requiring multiple fixed-length variants or complex adjustment mechanisms
Solution Approach 2:
The dynamic elastic nature of the spring elements allows them to automatically adjust to varying panel thicknesses during installation. The elements can compress and extend laterally to reach the optimal fixing position, eliminating the need for complex adjustable mechanisms while maintaining adaptability across different panel specifications
3Reliability
If rigid fixing elements are used, then the structure is simple, but the fastening nut cannot provide anti-rotational security and stable joint
Solution Approach 1:
The patent transforms the fixing elements from rigid to elastic by using spring material that can laterally deform. This elasticity enables the elements to flexibly engage with the panel surface, providing continuous rotational preventing force while accommodating surface variations, thereby achieving reliable anti-rotational security without excessive structural complexity
Solution Approach 2:
The spring elements provide dynamic rotational prevention by laterally deforming to maintain optimal contact force with the panel. This dynamic adaptation ensures stable joint formation during tightening operations, preventing undesirable rotation while automatically adjusting to different installation conditions and panel geometries
