Vehicle Door Seal With Hidden Lighting for Discreet Interior Trim
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting signatures in motor vehicles lack originality and aesthetic integration within the passenger compartment, particularly on door panels, and are not discreetly integrated, leading to disappointing appearances.
Innovation Solution
A sealing strip for vehicle doors featuring a first lip covering interior trim and a light device under the lip, with an LED strip or reflective tube, retained by elastomer beads, creating a localized and discreet lighting effect that is easy to manufacture and assemble.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a seal is made opaque to prevent light leakage, then light leakage is prevented, but visual monitoring of the sealed space becomes impossible
Solution Approach 1:
The seal is divided into multiple segments or sections, with at least one segment being transparent while others can be opaque. This segmentation allows the seal to simultaneously prevent light leakage through opaque portions and enable visual monitoring through transparent portions, resolving the contradiction between these two requirements.
Solution Approach 2:
Different portions of the seal have different optical properties - some areas are made opaque to prevent light leakage, while specific local areas are made transparent to allow visual monitoring. This local differentiation of properties allows the seal to fulfill both functions of preventing light leakage and enabling observation of the sealed space.
2Difficulty of detecting and measuring
If a transparent seal is used to enable visual monitoring, then visual monitoring becomes possible, but light leakage occurs
Solution Approach 1:
The seal is divided into multiple segments or sections, with at least one segment being transparent while others can be opaque. This segmentation allows the seal to simultaneously prevent light leakage through opaque portions and enable visual monitoring through transparent portions, resolving the contradiction between these two requirements.
Solution Approach 2:
Different portions of the seal have different optical properties - some areas are made opaque to prevent light leakage, while specific local areas are made transparent to allow visual monitoring. This local differentiation of properties allows the seal to fulfill both functions of preventing light leakage and enabling observation of the sealed space.
3Difficulty of detecting and measuring
If a luminous device is added to enable space identification, then space identification becomes possible, but device complexity increases
Solution Approach 1:
The luminous device is integrated directly into the seal structure itself, merging the lighting function with the sealing function. This combination eliminates the need for separate external lighting systems, reducing overall device complexity while still enabling space identification and visual monitoring capabilities.
Solution Approach 2:
The seal is designed to perform multiple functions simultaneously: it provides sealing, prevents light leakage, enables visual monitoring through transparency, and incorporates luminous capabilities for space identification. This multi-functionality reduces the need for separate components, thereby reducing overall device complexity.
