Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bead-weaving looms lack convenience in adjusting thread tension and length, making it difficult to produce beaded fabrics of varying lengths and qualities.
Innovation Solution
The beading loom features a unique design with thread fixing and supporting shafts, operation mechanisms, and a length adjustment mechanism, allowing for adjustable thread tension and stepwise length adjustments, enabling efficient production of beaded fabrics with uniform tension and varying lengths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional beading looms are used, then the basic beading function is achieved, but the adjustment of thread tension and length is difficult, reducing convenience and quality
Solution Approach 1:
The patent implements adjustable thread supporting shafts that can change their position along the longitudinal axis, allowing dynamic adjustment of the distance between shafts. This enables variable thread tension and length control during the beading process, directly improving ease of operation while maintaining a relatively simple overall structure through controlled adaptability
Solution Approach 2:
The invention changes the physical parameter of the distance between thread supporting shafts to control thread tension and length. By adjusting this spatial parameter, the system achieves variable thread tension without requiring complex mechanical tensioning devices, thus improving operational convenience while limiting structural complexity increase
2Adaptability or versatility
If fixed thread supporting shafts are used, then the structure is simple, but the production of beaded fabrics of varying lengths and qualities is difficult
Solution Approach 1:
The thread supporting shafts are designed to be movable along the longitudinal axis rather than fixed, enabling the distance between shafts to be adjusted according to different beading requirements. This dynamic configuration allows the production of beaded fabrics with varying lengths and qualities while maintaining a relatively simple adjustable structure
Solution Approach 2:
The adjustable thread supporting shaft system serves multiple functions: it controls thread tension, determines fabric length, and accommodates different beading patterns. This multi-functionality increases adaptability for producing various beaded fabrics without requiring separate specialized devices for each function

AI summary
A beading loom includes two side supports spaced apart in a lateral direction, and a plurality of shafts rotatably connected to the supports. The shafts include first and second thread fixing shafts, and first and second thread supporting shafts. Each of the first and second thread supporting shafts includes first and second thread supporting portions elongated in the lateral direction. In each thread supporting shaft, the first and the second thread supporting portions are provided at different positions in the circumferential direction of the shaft. Each of the first and the second thread supporting portions includes a plurality of grooves arranged at a pitch in the lateral direction. The pitch of the grooves of the first thread supporting portion differs from the pitch of the grooves of the second thread supporting portion.
