Vehicle Gauge Support Segmentation for Steering Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Supporting a front cowl, headlight unit, and gauge on a steering apparatus with a synthetic resin stay is challenging due to bending issues caused by the weight of the gauge, leading to misalignment and gaps between components.
Innovation Solution
A vehicle design where the gauge is supported by a separate gauge stay, and the gauge cover is a separate member from the cowl stay, allowing for easier assembly and reduced bending, with the gauge cover capable of movement to maintain proper alignment during steering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If a synthetic resin stay is used instead of a metal stay, then the weight of the vehicle body is reduced, but the stay becomes larger and more prone to bending
Solution Approach 1:
The stay is divided into multiple separate members (cowl stay, gauge stay, gauge cover) instead of using a single integrated metal stay. This segmentation allows each synthetic resin component to be optimized independently for strength and weight, reducing overall body weight while maintaining adequate bending resistance through proper structural design of each segment.
2Device complexity
If the gauge support is integrated with the stay main part, then the number of parts is reduced, but the weight of the gauge causes the end of the gauge support to bend down
Solution Approach 1:
The integrated gauge support structure is segmented into separate components (cowl stay, gauge stay, gauge cover) to prevent bending under gauge weight. This segmentation eliminates the alignment issues caused by bending while maintaining reasonable assembly complexity through modular design.
Solution Approach 2:
A separate gauge stay acts as an intermediary member between the steering apparatus and the gauge, providing dedicated support that prevents the gauge weight from causing bending in the cowl stay. This intermediary structure maintains proper alignment precision while keeping the overall design manageable.
3Reliability
If the gauge support and front cowl are bolted on, then the assembly is secure, but positioning becomes difficult when the gauge support bends under weight
Solution Approach 1:
The assembly is segmented into separate members (cowl stay, gauge stay, gauge cover) that can be positioned and secured independently. This segmentation eliminates the positioning difficulty caused by bending while maintaining secure assembly through dedicated attachment points for each component.
