Light-Transmitting Beading with Colored Portion to Hide Sewing Threads
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Beading on automotive seats with high light transmittance materials makes sewing threads visible from the outside, detracting from the appearance.
Innovation Solution
Incorporating a colored portion in the beading, either in the linear member or leg portion, which has a lower light transmittance than the main light-transmitting material, to suppress the visibility of sewing threads when viewed from above, and potentially using two-color molding for integration and decoration enhancement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the linear member is formed of a light-transmitting material to enhance decoration property, then the aesthetic appearance is improved, but the sewing thread becomes visible through the linear member
Solution Approach 1:
The invention applies different optical properties to different regions of the beading structure. The linear member maintains high light transmittance for aesthetic purposes, while the leg portion incorporates a colored portion with lower light transmittance to specifically mask the sewing thread. This local differentiation of material properties resolves the contradiction by allowing each region to fulfill its specific function.
Solution Approach 2:
The invention utilizes coloration in the leg portion to alter light transmission characteristics. By incorporating a colored portion with lower light transmittance in the leg portion, the sewing thread becomes less visible while the linear member retains its transparent, decorative appearance. This color-based differentiation addresses the visibility issue without compromising aesthetic goals.
2Object-generated harmful factors
If the colored portion is added to suppress thread visibility, then the outward appearance is improved, but the device complexity increases
Solution Approach 1:
The invention merges the colored portion and the leg portion into a single integrated component. By forming these elements as one unified structure, the design avoids the complexity of assembling separate parts. The colored portion is incorporated within or as part of the leg portion, simplifying manufacturing while achieving the thread-masking function.
Solution Approach 2:
The invention employs composite construction by combining materials with different optical properties within the leg portion. The colored portion uses material with lower light transmittance compared to the linear member, creating a composite structure that achieves thread obscuration. This material differentiation is implemented in a way that maintains manufacturing simplicity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The colored portion effectively hides the sewing threads, enhancing the outward appearance and design of the beading while maintaining the decorative effect of the light-transmitting material.
Implementation Method 1
The colored portion has a smaller quantity of transmitting light than that of the main portion

AI summary
Embodiments of the present invention may include beading for decorating a target member. The beading has a linear member, a leg portion and a colored portion. The linear member has a main portion formed of a light-transmitting material. The linear member has a first end and a second end opposite the first end on an outer periphery thereof. The leg portion extends from the first end of the linear member. The leg portion has a sewn portion that is sewn onto the target member by sewing thread. The colored portion is provided in the linear member or the leg portion. The colored portion has a smaller quantity of transmitting light than that of the main portion. The colored portion is situated and configured to suppress the visibility of the sewing thread when the linear member is seen from above the second end.
