Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing daisy chains are prone to tearing at the hoops due to the separation of one-piece webbing units during long-term use, posing safety hazards.
Innovation Solution
A daisy chain design featuring two webbings with different thermal shrinkage rates, seamlessly jointed at both ends, with one-piece webbing units woven on opposite sides and uniformly distributed intervals, along with an arc-shaped loop between adjacent units, ensuring structural integrity and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If one-piece webbing units are sewn by a needle swing machine at intervals with loops between adjacent units, then the daisy chain can be manufactured with simple structure, but the webbing units are prone to tearing during long-term use
Solution Approach 1:
The patent merges the first webbing and second webbing into a compound webbing structure where both webbings are seamlessly jointed together at two ends. This combining of multiple webbings into a unified compound structure eliminates the separation issue that causes tearing at hoops, while maintaining manufacturing efficiency through integrated construction.
Solution Approach 2:
The patent employs composite material construction by using two different webbings (first webbing and second webbing) with different thermal shrinkage characteristics. These composite webbings are jointed together to form a compound webbing that leverages the properties of both materials to prevent tearing while maintaining structural integrity during long-term use.
2Strength
If compound sections are uniformly distributed along the daisy chain at intervals, then structural strength is improved, but the complexity of the daisy chain structure increases
Solution Approach 1:
The patent applies segmentation by creating multiple compound sections along the daisy chain at uniform intervals. Each compound section consists of the first and second webbings jointed together, providing localized strength enhancement. This segmented approach distributes structural reinforcement throughout the chain without requiring complete complexity throughout the entire structure.
Solution Approach 2:
The patent implements local quality by concentrating the compound webbing structure (first webbing + second webbing) at specific intervals along the daisy chain rather than uniformly throughout. This allows the chain to have enhanced strength where compound sections are located while maintaining simpler construction in other areas, optimizing the balance between strength and complexity.

AI summary
The present invention discloses a daisy chain, comprising a first webbing (1) and a second webbing (2), which are different in thermal shrinkage; the first webbing (1) and the second webbing (2) are seamless jointed together at two ends thereof, respectively; one-piece webbing units (3) are woven relative to one another on opposite sides of the first webbing (1) and the second webbing (1), the one-piece webbing units (3) being uniformly distributed along the daisy chain at intervals; furthermore, a loop (4) is further provided between the adjacent one-piece webbing units (3). The arrangement of one-piece webbing units (3) avoids the safety hazards caused by the separation of the first webbing (1) from the second webbing (1) when the loop is long-term stressed. The daisy chain provided by the present invention is simple in structure, and safe and reliable in use.
