Buckling Washer Locking Structure to Prevent Screw Slanting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional washers fail to securely fix objects in position, leading to improper assembly as screws often become slanted.
Innovation Solution
A locking structure comprising a stud sleeve, a buckling washer with a carrying portion and hook portions, and a screw, which allows for the washer to move relative to the object along a fine adjustment plane, limiting movement and preventing screw slanting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional washer is used to fix an object, then the assembly process is simple, but the object cannot be securely fixed in position and screws become slanted
Solution Approach 1:
The washer is divided into multiple functional segments: a carrying portion for supporting the object, and multiple hook portions extending outward to engage with the object's peripheral surface. This segmentation allows each part to perform its specific function independently, improving fixing reliability while maintaining reasonable structural complexity
Solution Approach 2:
The hook portions extend outward from the carrying portion in a radial direction, adding a dimensional element that enables engagement with the object's peripheral surface. This dimensional change transforms the washer from a simple flat disc to a three-dimensional structure that can securely fix the object in position and prevent screw slanting
2Manufacturing precision
If the washer structure is made more complex to prevent screw slanting, then assembly reliability improves, but the device complexity increases
Solution Approach 1:
The hook portions are strategically positioned at specific locations on the carrying portion to engage with corresponding features on the object's peripheral surface. This local quality approach ensures that precision is applied only where needed for assembly alignment, rather than requiring the entire washer structure to be complex
Solution Approach 2:
The buckling washer is designed to be movable relative to the object along a fine adjustment plane perpendicular to the assembling direction, allowing dynamic adjustment during assembly to accommodate minor misalignments while maintaining precise final positioning
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 locking structure effectively secures objects by limiting movement along multiple axes, ensuring proper assembly and preventing screw slanting.
Implementation Method 1
The buckling washer is movable relative to the object along a fine adjustment plane perpendicular to the assembling direction
