Vehicle Display Mounting Plate With Split Rigidity Against Distortion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices for vehicles suffer from distortion issues due to vibrations, which can impair the viewability of the display unit, as the deformation of the housing is not adequately absorbed, leading to uneven brightness and poorer display quality.
Innovation Solution
The display device is designed with a plate having a first region with higher rigidity for the display unit and a second region with lower rigidity for the housing, where the housing is mounted, and the housing features a slit structure to absorb distortion, reducing the transfer of deformation to the display unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the housing is secured to the vehicle using screws, then the display device is firmly mounted, but distortion and warp occur on the housing and display unit due to vibration and mounting stress
Solution Approach 1:
The plate is designed with non-uniform thickness, creating regions of different rigidity. The first region (display unit mounting area) has greater thickness and higher rigidity to resist distortion, while the second region (housing mounting area) has lesser thickness and lower rigidity to absorb distortion. This local quality differentiation resolves the contradiction by providing both mounting stability and distortion prevention.
2Object-affected harmful factors
If an elastically deformable washer is used to mount the display unit, then distortion on the vehicle side is inhibited, but distortion might still be transferred to the display unit when vehicle distortion is large
Solution Approach 1:
The plate's non-uniform thickness creates localized rigidity differences that work together with the elastically deformable washer. The first region's higher rigidity provides a stable mounting surface for the display unit, while the second region's lower rigidity absorbs distortion, enhancing the washer's distortion absorption capability and preventing distortion transfer.
Solution Approach 2:
The mounting system combines the elastically deformable washer with the plate structure of varying thickness. This composite approach integrates two distortion-mitigation mechanisms: the washer's elasticity and the plate's differential rigidity, providing superior distortion absorption and protection for the display unit.
3Ease of manufacture
If the plate has uniform rigidity, then manufacturing is simpler, but distortion from the housing side is transferred to the display unit
Solution Approach 1:
The plate is designed with non-uniform thickness, creating regions of different rigidity. The first region (display unit mounting area) has greater thickness and higher rigidity to resist distortion, while the second region (housing mounting area) has lesser thickness and lower rigidity to absorb distortion. This local quality differentiation resolves the contradiction by providing both mounting stability and distortion prevention.
