Vehicle Display Mounting With Elastic Depth Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices in motor vehicles face challenges such as the need for high brightness, secure fixation to withstand vibrations, and achieving a flush surface alignment for optimal ergonomics and image quality, which is complicated by manufacturing tolerances and clearances, leading to potential image distortion and unsightly gaps.
Innovation Solution
The use of elastic means, such as elastomer pads, silicone pads, and compression springs, between the display screen and the housing allows for precise adjustment of the display's position, minimizing gaps and compensating for manufacturing tolerances, ensuring better ergonomics and display quality by enabling continuous depth adjustment and reducing internal constraints.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If rigid fixing means are used to secure the display screen to the housing, then the display screen is firmly fixed and resistant to vibrations, but manufacturing tolerances and clearance variations cause gaps and misalignment between the display surface and the facade
Solution Approach 1:
The patent changes the physical state of the fixing means from rigid to elastic, allowing the fixing elements to deform elastically under compression. This enables continuous adjustment of the display screen position in depth, compensating for manufacturing tolerances and clearance variations while maintaining firm fixation against vibrations.
Solution Approach 2:
The patent introduces dynamic adjustment capability through elastic fixing means that can continuously adapt their compression level. This allows the system to compensate for dimensional variations and achieve precise surface alignment (flushy display) while maintaining reliable fixation, transforming a static rigid connection into a dynamically adjustable elastic connection.
2Ease of operation
If the display screen is positioned closer to the facade surface for ergonomic reasons, then ergonomics and image quality improve, but manufacturing tolerances make it difficult to control the exact position and eliminate gaps
Solution Approach 1:
The patent employs elastic fixing means that can be compressed to different degrees, enabling continuous adjustment of the display screen's depth position. This allows the screen to be positioned at the optimal ergonomic distance from the facade surface while compensating for manufacturing tolerances, ensuring consistent alignment across different production batches.
3Reliability
If heavy fixing means are used to withstand vibrations, then fixation reliability improves, but the overall weight of the display device increases
Solution Approach 1:
The patent utilizes elastic materials (such as elastomers or springs) that provide both the necessary mechanical strength to withstand vibrations and the flexibility to compensate for tolerances. These elastic fixing means offer a weight-efficient solution compared to heavy rigid fixing mechanisms, achieving vibration resistance through material properties rather than increased mass.
