Vehicle Display Screen Mounting Assembly Omni-Directional Energy Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle-specific brackets for display screens are typically designed to absorb energy in only one direction, failing to provide adequate omni-directional energy absorption and durability against various forces and impacts.
Innovation Solution
A vehicle display screen mounting assembly featuring a casing with protrusions and bushings that allow for omni-directional energy absorption, combined with an attachment feature and bracket system that can absorb energy in any direction through a two-step energy management system, including a bushing with adjustable properties and tabs that deform differently to manage loads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a vehicle-specific bracket is designed to absorb energy in a single direction, then the bracket structure can be simplified, but the reliability and durability under various forces and impacts deteriorate
Solution Approach 1:
The mounting assembly is divided into separate functional components: a rigid bracket for structural support and attachment, and a separate bushing component for energy absorption. This segmentation allows each component to be optimized for its specific function while maintaining overall system reliability under multi-directional forces.
2Ease of manufacture
If a vehicle-specific bracket is designed for single-direction energy absorption, then the manufacturing process can be simplified, but the adaptability to different impact directions deteriorates
Solution Approach 1:
The bushing acts as an intermediary component between the bracket and the instrument panel, specifically designed to absorb energy from impacts in any direction. This mediator handles the complex energy absorption requirements while the bracket maintains its simple structural attachment function.
3Reliability
If a universal mounting assembly is designed to absorb energy in any direction, then the reliability and durability improve, but the device complexity increases
Solution Approach 1:
The bracket and bushing are merged into a single integrated mounting assembly that combines the rigid structural attachment function with the energy absorption function. This integration ensures reliable performance under various forces while maintaining a relatively simple overall structure.
