Profiled Retaining Section for Piped Seam Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing profiled retaining sections are unable to reliably and simply position seams trimmed with piping, as they lack a suitable positioning element for such designs.
Innovation Solution
A profiled retaining section with an upper region designed like piping, a center region for connection to decorative layers, and an anchor that can be laterally compressed to secure in a groove, allowing for secure and visible positioning of seams with piping or welting, composed of materials like TPE-E with adjustable hardness and compression capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional profiled retaining section with a groove is used, then seams without piping can be positioned, but seams with piping cannot be reliably positioned
Solution Approach 1:
The profiled retaining section is divided into three functional regions: an upper piping-like region for receiving the piping, a center region for connection to decorative layers, and a lower anchor region for securing in the groove. This segmentation allows each region to perform its specific function, enabling reliable positioning of piped seams while maintaining versatility.
Solution Approach 2:
The profiled retaining section is designed as a multi-functional element that can handle both piped and non-piped seams. The upper region's piping-like design receives piping when present, while the center and lower regions provide universal connection and anchoring functions for all seam types, achieving both adaptability and reliability.
2Strength
If an anchor with large width is used for secure retention, then retention strength is improved, but the anchor cannot be introduced into narrow grooves
Solution Approach 1:
The anchor's width parameter is made variable through compressible material selection. The anchor can be compressed laterally to a smaller width for introduction into narrow grooves, then expands to its full width within the groove to provide strong retention. This parameter change resolves the contradiction between installation ease and retention strength.
Solution Approach 2:
The anchor is made from compressible plastic material that allows lateral compression, enabling it to be inserted into narrow grooves and then expand to provide strong retention. This flexibility allows the anchor to adapt its dimensions based on installation requirements versus retention requirements.
3Shape
If the upper region is designed with piping-like structure for decorative effect, then appearance is improved, but structural complexity increases
Solution Approach 1:
The profiled retaining section merges the decorative piping element with the functional anchoring structure into a single integrated component. The upper piping-like region, center connection region, and lower anchor region are formed as one piece from the same material, reducing overall structural complexity while maintaining decorative appearance.
Solution Approach 2:
The entire profiled retaining section is made from a single compressible plastic material that provides both the decorative piping-like appearance and the functional properties needed for connection and anchoring. This use of a single composite material simplifies the structure compared to assembling multiple different materials.
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
Enables reliable and simple positioning of seams with piping or welting, providing a secure retention mechanism and decorative effect while allowing for flexibility and reduced wear in high-stress areas.
Implementation Method 1
The anchor is designed to be introduced in a groove having a lesser width than the anchor itself, which is to say the anchor can be compressed in the lateral direction. When the anchor is pushed into a groove, it is laterally compressed and exerts a force on the groove in the lateral direction.

AI summary
A profiled retaining section for positioning a seam connecting two decorative layers includes an upper region, a center region and a lower region forming at least one anchor. The upper region is designed as a piping, or in the manner of a piping, for protruding over a visible side of the skins to be positioned. The center region includes two sides to be sewn to the decorative layers. The anchor is designed to be introduced in a groove having a lesser width than the anchor itself and to exert a force on the groove in the lateral direction. The upper region, the center region and the anchor are integral with each other and arranged in the vertical direction relative to each other. Also described is a composite part that uses the profiled retaining section.
