Vehicle Display Support Plate Structure to Prevent Surface Distortion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
On-vehicle devices with a body device installed on the back surface of a display device often experience distortion on the information display surface due to improper fixation methods.
Innovation Solution
Incorporating a support plate with a plate spring part that is bent and continuous with a fixation part, which is fixed on the top surface of the body device and supports the back surface of the display device, reducing stress and ensuring proper grounding and electrical connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a body device is fixed directly on the back surface of a display device, then the structure is simple, but distortion occurs on the information display surface
Solution Approach 1:
A support plate is introduced as an intermediary component between the body device and the display device. The support plate includes a fixation part that attaches to the body device and a support part that contacts the back surface of the display device, thereby preventing direct fixation-induced distortion while maintaining structural simplicity
Solution Approach 2:
The support plate is divided into two functional segments: a fixation part for attaching to the body device and a support part for contacting the display device back surface. This segmentation allows each part to perform its specific function optimally, preventing distortion while keeping the overall structure simple
2Strength
If a rigid support structure is used to fix the display device, then the fixation is strong, but stress is transmitted to the display device causing distortion
Solution Approach 1:
The support part of the support plate is designed with flexibility to act as a buffer between the rigid body device and the display device. This flexible structure maintains fixation strength while absorbing stress to prevent distortion on the display surface
Solution Approach 2:
The support plate is designed to absorb and distribute fixation stress before it reaches the display device. This beforehand cushioning prevents stress transmission that would cause distortion, while maintaining strong fixation through the fixation part
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
Prevents distortion on the information display surface by absorbing pushing forces and ensuring reliable electrical connections, allowing for stable and clear information display even with slight variations in inclination angles.

AI summary
An on-vehicle device includes a display device, a body device, and a support plate. The body device is installed on a back surface of the display device. The support plate includes a fixation part with a plate shape that is fixed on a top surface of the body device and a support part with a plate shape that is continuous with the fixation part and is formed so as to be bent, and supports a back surface of the display device by a plate spring part that is formed on the support part.
