Airbag-Mounted Display Layout for Unobstructed Inflation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display modules in vehicles are not designed to accommodate airbag inflation without hindering the airbag's expansion, leading to potential splashing and increased injury risk during collisions.
Innovation Solution
The display module is positioned to avoid overlap with the inflator and airbag when not inflated, securing to the vehicle structure during inflation, allowing the airbag to expand freely while maintaining the display's stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the display module is installed on the airbag without considering inflation space, then the device complexity is reduced, but the airbag inflation is hindered and safety is compromised
Solution Approach 1:
The display module is segmented into a first display module and a second display module, positioned at different locations on the airbag. This segmentation allows each module to be independently positioned to avoid interference with airbag inflation while maintaining overall system functionality.
Solution Approach 2:
The patent utilizes the three-dimensional space on the airbag surface by positioning display modules at different locations and orientations. This dimensional arrangement ensures that display modules do not occupy the same space as the inflator or hinder inflation expansion.
2Reliability
If the display module is positioned to avoid the inflator, then airbag inflation is ensured, but the display module may splash during inflation
Solution Approach 1:
A adhesive layer or mounting structure acts as an intermediary between the display module and the airbag surface. This intermediary secures the display module firmly during inflation, preventing splash while allowing the airbag to expand freely.
Solution Approach 2:
The display module is pre-positioned and secured on the airbag surface before inflation occurs. This preliminary positioning ensures that the module remains in place during the inflation process, preventing harmful splash while maintaining proper inflation functionality.
3Area of stationary object
If the electronic module overlaps with the inflator in top-view direction, then space utilization is improved, but the inflator may be hindered during inflation
Solution Approach 1:
The patent transitions from two-dimensional top-view overlap to three-dimensional spatial arrangement. Display modules are positioned on the airbag surface at locations that may appear to overlap in top-view but are actually positioned to avoid interfering with the inflator's inflation path and operation.
Solution Approach 2:
Different regions of the airbag surface are assigned different functions: areas远离 the inflator are designated for display modules, while the central inflation path is reserved for inflator operation. This local quality differentiation ensures both space utilization and reliable inflator operation.
Data Source
AI summary
An electronic device including an electronic module, an inflator and an airbag is disclosed. The airbag is configured to be inflated by a gas produced by the inflator. The electronic module is disposed on the airbag and includes a first surface, a corner connecting with the first surface and a second surface opposite to the first surface. When the airbag is not inflated by the gas, at least a portion of the second surface is disposed between the first surface and the air bag, and the electronic module is at least partially overlapped with the airbag and not overlapped with the inflator in a top-view direction of the electronic module. When the airbag is inflated by the gas, the airbag contacts the corner of the electronic module, and the airbag at least partially contacts the first surface of the electronic module in the top-view direction of the electronic module.
