Multifunction Vehicle Door Assembly with Laser Emitter
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle side mirror and door handle systems lack a reliable method to visually warn pedestrians and other vehicles of the vehicle's open door area, leading to potential accidents, and current solutions require complex assembly processes and multiple suppliers, increasing costs and time in manufacturing.
Innovation Solution
A multifunction assembly incorporating a fixed laser emitter and ultraviolet light in the side door of a vehicle, which projects a laser line onto the ground to indicate the door's open area, combining with ultraviolet-activated luminescent materials to enhance visibility and safety, while allowing for zero-cost and zero-time assembly by integrating with existing mirror and handle systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a laser emitter and ultraviolet light are integrated into the side door assembly, then safety and visibility are improved by marking the open door area, but device complexity increases
Solution Approach 1:
The patent combines the laser emitter and ultraviolet light emitter into a single integrated assembly that is mounted on the vehicle door. This merging of multiple light-emitting functions into one device reduces the number of separate components needed while achieving both safety marking and visibility enhancement functions simultaneously.
Solution Approach 2:
The integrated assembly serves multiple functions: it projects a laser line to mark the open door area for safety, emits ultraviolet light to activate luminescent materials for visibility, and can be combined with existing door assemblies. This multi-functionality improves safety without requiring separate dedicated devices for each function.
2Reliability
If additional laser emitter components are added to the vehicle door, then safety warning capability is improved, but manufacturing cost and assembly time increase
Solution Approach 1:
The laser emitter assembly is designed to be integrated with existing vehicle door assemblies, combining multiple functions into a single manufacturing unit. This approach allows manufacturers to produce one integrated component rather than assembling multiple separate parts, reducing both manufacturing complexity and assembly time.
Solution Approach 2:
The integrated assembly can be mounted on various door types and configurations, serving as a universal solution that works with different vehicle models. This versatility simplifies the manufacturing process by using a standardized component across different platforms rather than requiring model-specific customizations.
3Manufacturing precision
If a fixed laser emitter is used to project a laser line, then safety marking precision is improved, but device complexity increases due to additional wiring and assembly steps
Solution Approach 1:
The laser emitter is designed as a self-contained, fixed unit with integrated optics that projects the laser line without requiring complex external wiring or adjustment mechanisms. By extracting the essential function of precise marking into a standalone fixed emitter, the system achieves precision while minimizing the complexity of surrounding infrastructure.
Solution Approach 2:
The fixed laser emitter is designed to automatically project the safety marking line when activated, without requiring manual adjustment or complex control systems. The device serves itself by having built-in positioning and projection capabilities that eliminate the need for additional wiring harnesses or assembly adjustments.
