A-Pillar Display Retention With Tool-Free Height Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle display systems are inefficient at retaining their position during impact scenarios and do not account for differences in driver eye height, requiring specific tooling for adjustment and lacking stability for larger and heavier systems.
Innovation Solution
A vehicle display retention system mounted to the inside of a vehicle, specifically the A-pillar, featuring a display unit, attachment components, intermediate attachments, and a grab bar with a mounting arm that includes a fracture point for fail-safe retention, and an adjustment mechanism for height adjustment without additional tooling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a plastic wire retention system is used to connect the electronic display system to the headliner or windshield, then the display system can be retained during impact scenarios, but the system lacks stability and robustness for larger and heavier electronic display systems
Solution Approach 1:
The retention system is divided into separate functional components: a mounting bracket attached to the display, a retention strap independently attached to the vehicle structure, and connection points at both the display and vehicle ends. This segmentation allows the weak plastic wire to be replaced with a stronger retention strap while maintaining the overall retention function.
Solution Approach 2:
The mounting bracket acts as an intermediary component between the display system and the retention strap. It provides a robust attachment point on the display side, replacing the direct connection that would otherwise rely on the weak plastic wire, thereby enabling the system to support heavier displays.
2Adaptability or versatility
If specific tooling is required to facilitate the adjustment of the display system, then the display system can be adjusted to different positions, but the user requires additional time and difficulty to adjust the display system
Solution Approach 1:
The mounting bracket incorporates a self-adjusting mechanism with a release button that allows the retention strap to be easily detached and repositioned. Users can adjust the display system without requiring additional tooling, as the bracket's design enables manual operation through the release button mechanism.
3Ease of operation
If the display system is mounted to the windshield or headliner, then the display is visible to the driver, but the system does not account for differences in driver eye height
Solution Approach 1:
The retention system transforms the static mounting to the windshield or headliner into a dynamic, adjustable configuration. The retention strap can be detached from one anchor point and reattached to another, allowing the display to be repositioned vertically to accommodate different driver eye heights while maintaining visibility.
4Reliability
If a retention strap is used to securely retain the display unit to the A-pillar, then the display remains stable during impacts, but the system complexity increases
Solution Approach 1:
The mounting bracket serves multiple functions: it attaches to the display system, provides attachment points for the retention strap, and enables adjustment of the display position. By consolidating these functions into a single component, the system achieves high retention reliability without proportionally increasing complexity.
