Light Guide Member Mounting Assembly for Automotive Interior
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
It is challenging to mount a long linear light guide member on a vehicular interior component in an appropriate, stable, and precise manner, as existing methods often result in uneven light distribution and potential for the light guide member to move away from its intended position.
Innovation Solution
A mounting assembly for a lighting device and vehicular interior component that includes a light guide member holder with a support portion and a fitting portion, where the light guide member is secured on the vehicular exterior surface using clips and an elastic member, ensuring stable and precise positioning by fitting into stopper holes and covering the light guide member to prevent light leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a long linear light guide member is mounted on a vehicular interior component, then light can be distributed across multiple areas, but it becomes difficult to position and secure the light guide member accurately and stably
Solution Approach 1:
The light guide member mounting structure is divided into multiple discrete mounting positions with individual stopper holes distributed along the vehicular interior component. This segmentation allows the long light guide member to be positioned at multiple precise locations rather than requiring a single complex mounting mechanism, enabling accurate light distribution across multiple areas while simplifying the mounting process
Solution Approach 2:
Stopper holes are introduced as intermediary elements between the vehicular interior component and the light guide member. These stopper holes receive corresponding protrusions on the mounting member, creating a precise positioning interface that ensures accurate and stable mounting of the light guide member without requiring complex alignment procedures
2Illumination intensity
If a long linear light guide member is mounted on a vehicular interior component, then light can be distributed across multiple areas, but the light guide member may move away from its intended position
Solution Approach 1:
The mounting structure uses multiple discrete mounting positions with individual stopper holes distributed along the component. Each stopper hole provides a stable anchoring point, and the cumulative effect of multiple distributed mounting points ensures the long light guide member remains securely positioned without moving from its intended location while maintaining light distribution functionality
Solution Approach 2:
The stopper holes serve as intermediary positioning elements that physically constrain the light guide member at multiple locations. By receiving corresponding protrusions on the mounting member, these stopper holes prevent displacement and ensure the light guide member maintains its intended position, thereby improving mounting stability
3Illumination intensity
If a long linear light guide member is mounted on a vehicular interior component, then light can be distributed across multiple areas, but the mounting process becomes complex and difficult to perform
Solution Approach 1:
The mounting structure is segmented into multiple simple, identical mounting positions with stopper holes distributed along the component. This segmentation transforms a complex single-step mounting process into multiple simple, repeatable positioning operations, making the overall mounting process easier to perform while achieving comprehensive light distribution across multiple areas
Solution Approach 2:
Stopper holes are introduced as intermediary elements that simplify the mounting operation. These pre-formed holes provide automatic positioning guidance and secure attachment points, eliminating the need for complex alignment procedures or specialized mounting tools, thereby improving mounting operability while enabling multi-area light distribution

AI summary
A mounting assembly includes a lighting device, a vehicular interior component, and a light guide member mounting member with which the light guide member is mounted on the vehicular interior component. The lighting device includes a light source and a long light guide member. The vehicular interior component includes a through hole and a receiving member that includes a stopper hole near the through hole. The light guide member mounting member includes a support portion and a fitting portion that extends from the support portion and is fitted to the stopper hole. The support portion includes a curved wall that has a space defined by the curved wall and receives and supports a portion of the light guide member in the space to be opposite the through hole such that the light exits the light guide member is supplied to a vehicular interior surface side of the vehicular interior component.
