Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Shock absorber housings for vehicles often lack sufficient rigidity, leading to decreased driving stability and ride comfort, while increasing thickness or adding components to enhance rigidity can compromise spatial utility and fuel efficiency.
Innovation Solution
A shock absorber housing design featuring a housing cap with a curved surface portion and mounting features that securely couple the shock absorber, distributing load efficiently and reducing weight and thickness, thereby enhancing rigidity and fuel efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the thickness of the shock absorber housing is increased to secure rigidity, then the rigidity is improved, but the spatial utility deteriorates and the weight increases
Solution Approach 1:
The housing cap includes a curved surface portion extending from the upper end and formed in a curved surface shape that is convex upward. This curvature distributes stress more effectively across the structure, enhancing rigidity without requiring increased thickness, thereby resolving the contradiction between strength and volume.
2Strength
If additional constituent elements are used to secure rigidity of the shock absorber housing, then the rigidity is improved, but the device complexity increases
Solution Approach 1:
The housing cap integrates multiple functions into a single component: it covers the upper end of the shock absorber housing, provides a curved surface portion for structural rigidity, includes a seating surface for mounting the shock absorber, and incorporates mounting portions with holes for coupling. This merging of functions reduces the number of separate constituent elements while maintaining rigidity.
3Strength
If the weight of the shock absorber housing is increased to secure rigidity, then the rigidity is improved, but the fuel efficiency deteriorates
Solution Approach 1:
The curved surface portion of the housing cap provides enhanced rigidity through its geometric shape, which distributes mechanical loads more efficiently. This allows the use of lighter materials or thinner sections while maintaining the required rigidity, thereby reducing weight and improving fuel efficiency.
Solution Approach 2:
The design changes the geometric parameters of the housing cap, specifically incorporating a curved surface shape with specific convexity. This parameter change optimizes the strength-to-weight ratio, allowing the housing to maintain rigidity with reduced material usage and lower weight.
4Weight of moving object
If the shock absorber housing does not secure sufficient rigidity, then the weight and thickness are reduced, but the driving stability deteriorates
Solution Approach 1:
The curved surface portion of the housing cap enhances the structural rigidity needed for driving stability while keeping the overall weight reduced. The curvature provides structural reinforcement without requiring additional weight, thus maintaining stability with lighter construction.
