Dummy Vehicle Illuminant Layout for Crash-Reusable Light Simulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dummy elements used for simulating complex traffic situations and accidents are prone to damage due to rigid housings and frames, which can cause damage to both the dummy body and test vehicles during crashes, limiting their reusability and the realism of the simulation.
Innovation Solution
A dummy element design featuring an illuminant without a housing or frame, where the illuminant is fixed within an opening in the dummy body using methods like press fit, adhesive connection, or form fit, and a deformable circuit board that can absorb impact without damage, allowing for efficient and cost-effective reuse after crashes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If rigid housings and frames are installed in the dummy element to realistically simulate illumination devices, then the realism of the simulation is improved, but damage is caused to the dummy body and test vehicle during crashes
Solution Approach 1:
The patent extracts the housing and frame components from the illuminant assembly, leaving only the essential light-generating elements (LEDs, reflectors) without rigid protective enclosures. This removal eliminates the source of damage while preserving the visual appearance through graphic contours on the dummy body surface.
Solution Approach 2:
The patent creates a visual copy or representation of the illumination device housing through graphic contours applied to the dummy body surface. This graphical representation replicates the appearance of rigid housings without actually installing physical housing structures, thereby maintaining realism while avoiding damage.
2Stability of the object's composition
If rigid housings and frames are used in the illuminant, then the structural stability is improved, but the reusability after crash is reduced
Solution Approach 1:
The rigid housing and frame structures are completely removed from the illuminant assembly. Only the essential functional components (light sources, reflectors) remain, eliminating structural elements that would prevent reuse after damage to the dummy body.
Solution Approach 2:
The patent enables easy recovery and reuse of illuminant components after crashes by eliminating rigid housings that would be damaged or deformed. The simple construction allows components to be quickly removed, inspected, and reinstalled on replacement dummy bodies, maximizing reusability.
