Cup Holder Light Guide Member Gap Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing cup holders are prone to breaking of the light guide member due to direct transmission of external forces from the decorative finisher member, which can cause damage to the light guide member.
Innovation Solution
A cup holder design that includes a light-guide-member installation part and a finisher-member fixing part, where the finisher member is fixed with a gap from the light guide member, allowing external forces to be absorbed by the cup holder body, thereby reducing stress on the light guide member and preventing breakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the light guide member is clamped between the finisher member and cup holder body, then the structure is simple and easy to assemble, but the light guide member is vulnerable to breakage from external force
Solution Approach 1:
A buffer member is introduced as an intermediary component between the finisher member and the light guide member. This buffer member absorbs external forces applied to the finisher member, preventing direct transmission of force to the light guide member. The buffer member acts as a mediator that decouples the mechanical connection while maintaining the structural assembly, thus protecting the light guide member from breakage without complicating the overall structure.
2Volume of moving object
If the finisher member is directly connected to the light guide member, then the assembly is compact, but external force is directly transmitted to the light guide member causing breakage risk
Solution Approach 1:
The buffer member is pre-installed between the finisher member and the light guide member to provide beforehand cushioning. This cushioning element is positioned in advance to absorb and dissipate external forces before they can reach the light guide member. The buffer member acts as a protective barrier that is already in place to prevent force transmission, thus maintaining both compactness and strength.
3Reliability
If the light guide member is clamped tightly for secure mounting, then the mounting is reliable, but the light guide member becomes vulnerable to stress concentration and breakage
Solution Approach 1:
The buffer member serves as a mediator that decouples the mechanical stress between the finisher member and the light guide member. It allows the finisher member to be securely mounted while preventing stress concentration on the light guide member. The buffer member distributes and absorbs forces, maintaining mounting reliability without transmitting damaging stress to the light guide member.

AI summary
A cup holder includes a cup holder body which has a bottomed container shape and is capable of accommodating a beverage container; a decorative finisher member which is installed in an upper edge portion of the cup holder body; a light guide member which is interposed between a lower portion of the finisher member and an upper edge portion of the cup holder body. A light-guide-member installation part and a finisher-member fixing part are provided in the cup holder body. The finisher-member fixing part fixes the finisher member to the cup holder body in a state where the finisher member is separated with a gap part from an upper side of the light guide member.
