Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cases for disk storage apparatuses face challenges in enhancing shock resistance without increasing their size, as existing shock absorption methods require significant deformation that enlarges the case.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If plate springs and shock absorbers are deformed perpendicularly to the wall to absorb shock, then shock resistance is improved, but the case size increases
Solution Approach 1:
The patent applies curvature by forming the plate spring with an arched shape in the shock absorption direction. This curved structure allows the plate to deform more efficiently under perpendicular pressure, absorbing shock energy through elastic deformation without requiring excessive space. The arch shape distributes stress along the curve, enabling compact shock absorption while maintaining effectiveness.
Solution Approach 2:
The patent changes the physical parameters of the plate spring by controlling its thickness, material properties, and arch geometry. By optimizing these parameters, the plate achieves sufficient elastic deformation capability within a compact space, improving shock resistance without increasing case size. The flexible plate portion is designed with specific thickness and material characteristics to enable effective shock absorption in limited space.
2Reliability
If the case size is increased to ensure sufficient deformation of shock absorbers, then shock resistance is improved, but the compactness of the case is reduced
Solution Approach 1:
The arched configuration of the plate spring enables more efficient use of the available space. The curved geometry allows greater deformation capability within a shorter linear dimension, as the arch can compress and expand along its curved path rather than requiring linear space. This resolves the contradiction by providing sufficient shock absorption capacity without increasing the overall case length.
Solution Approach 2:
The patent transitions from linear shock absorption to three-dimensional deformation by using an arched structure. The plate deforms in multiple directions simultaneously (compression, bending, and lateral movement), utilizing spatial dimensions more effectively. This dimensional approach allows compact shock absorption without requiring increased case length in any single direction.
3Reliability
If deformable plates are used to absorb shock through elastic deformation, then shock resistance is improved, but the structural complexity increases
Solution Approach 1:
The patent merges the shock absorption function directly into the case wall structure itself, rather than adding separate shock absorbing components. The plate spring is integrated as part of the case wall, combining structural support and shock absorption functions in a single element. This integration reduces overall structural complexity while maintaining effective shock resistance.
Solution Approach 2:
The deformable plate serves multiple functions: it provides structural support as a case wall component, absorbs shock through elastic deformation, and maintains the integrity of the enclosed space. This multi-functionality reduces the need for additional separate components, thereby simplifying the overall structure while achieving improved shock resistance.
