U-Shaped Pipe Holder With Segmented Barbs for Secure Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pipe holders for surface heating systems fail to maintain secure fixation, especially when laying pipe bends, as the barbs compress in one direction and slide out through elongated holes in the insulation film, leading to insufficient support and potential dislodgment.
Innovation Solution
A U-shaped holder with inner and outer barbs divided by V-shaped incisions, allowing multiple barbs to engage at angles greater than 0° and less than 90°, increasing the number of barb sections and their multidirectional mobility, ensuring secure hooking and lateral support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the barbs are compressed in one direction when pressed into the film, then the holder is easy to install, but the barbs slide out through the pierced hole when lateral forces act on the holder
Solution Approach 1:
The barbs are divided into multiple barb sections by incisions, transforming a single barb into multiple segmented barbs. This segmentation allows the barbs to distribute lateral forces across multiple contact points on the foil, preventing slippage while maintaining ease of installation through the same insertion mechanism
2Stability of the object's composition
If the barbs are positioned to support the holder, then the holder provides stable fixation, but the barbs cannot support themselves when the holder is loaded laterally by pipe bends
Solution Approach 1:
The incisions create barb sections that can deflect in multiple directions rather than being constrained to a single plane. This multidimensional mobility allows the barbs to adapt to lateral forces from pipe bends by distributing loads across different angular orientations, enhancing both stability and lateral load resistance
3Reliability
If the number of barbs is increased to improve holding power, then the holder provides better fixation, but the device complexity increases
Solution Approach 1:
Instead of adding multiple separate barbs as distinct components, the invention segments existing barbs through incisions. This creates multiple barb sections from single barb structures, increasing holding power through increased contact points while avoiding the complexity of assembling multiple separate barb components
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 enhanced holder design significantly improves holding power by distributing lateral forces and preventing barb slippage through the foil, maintaining secure fixation even under bending loads and minimizing foil damage during installation.
Implementation Method 1
the barb has increased elasticity or flexibility, namely in the direction of the associated shaft and not in the opposite direction

AI summary
The holder (1) has a bar (1.3) connecting two legs (1.1, 1.2). The holder is designed in a U-shape. The legs include inner and outer barbed hooks (1.4, 1.5), which are divided into barbed hook sections (1.5n) by slots (1.6) such that a number of the barbed hooks is increased. The slots are designed in a V-shape. The barbed hook sections are provided diagonal relative to each other. The inner and outer barbed hooks are compressed during penetration into an insulation and a plastic film. The barbed hook sections are downwardly supported at the film.
