Vehicle Sensor Mount Vibration Suppression and Fingertip Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sensor mount structures for vehicles face challenges in suppressing vibration of display devices during travel while maintaining sufficient space for fingertip access to adjust the mirror's angle, particularly at the upper peripheral edge of the display device.
Innovation Solution
A sensor mount structure comprising a sensor device, a display device, a support member, an arm member, and a cover member, where the arm member's upper end is attached to the support member covering the sensor device, and its lower end to the display device, with a cover member that secures fingertip access by maintaining a longer distance at the display device's end portion, enhancing vibration suppression and adjustability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the arm member is shortened to suppress vibration of the display device, then vibration suppression is improved, but it becomes difficult to secure space for fingertip access at the upper side of the upper peripheral edge
Solution Approach 1:
The patent introduces a cover member that extends in the width direction (lateral dimension) to create fingertip access space, rather than increasing space in the length direction (vertical dimension). This dimensional shift allows the arm member to remain short for vibration suppression while still providing adequate access space through lateral extension of the cover member.
Solution Approach 2:
The cover member acts as an intermediary element between the short arm member and the display device, providing the necessary fingertip access space without requiring the arm member to be longer. The cover member mediates the conflict between compact structure and operational accessibility.
2Reliability
If the arm member length is reduced to improve vibration suppression, then display device stability is improved, but the space for angle adjustment access is reduced
Solution Approach 1:
The cover member extends in the width direction to create access space, allowing the arm member to be shortened for improved stability while maintaining adjustment accessibility through lateral space provision.
Solution Approach 2:
The support structure is segmented into the arm member and the cover member, with each performing distinct functions. The arm member provides structural support and vibration suppression, while the cover member provides access space, allowing optimization of both functions independently.
3Ease of operation
If the cover member extends further to improve fingertip access space, then ease of operation is improved, but the cover member shape becomes more complex
Solution Approach 1:
The cover member is designed with different extensions at different locations: it extends further in the width direction at the upper side to provide fingertip access space, while maintaining a simpler form elsewhere. This localized differentiation provides necessary access space without making the entire cover member overly complex.
Solution Approach 2:
The cover member features asymmetric extension, protruding more at the upper side (where fingertip access is needed) compared to other sides. This asymmetric design efficiently provides access space where required while minimizing overall structural complexity.
