Spiral-Reinforced Belt Joining by Compression Wire Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing method for joining a belt with interpenetrated spirals is complicated and risky due to the difficulty in extracting the transverse wire, which can damage the belt and requires additional steps like incising and lubricant application.
Innovation Solution
Compressing the belt along transverse zones parallel to the wire to be removed simplifies the extraction of the transverse wire by increasing the spiral size, reducing the risk of damage and eliminating the need for incising and lubricant application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the transverse wire is extracted by conventional methods (incising, lubricant application, manual extraction), then the wire can be removed to disengage spirals, but the process becomes complicated and the belt is at risk of damage
Solution Approach 1:
The patent applies compression force to the belt, changing the physical state of the spiral structure. This compression causes the spiral windings to expand outward, increasing the gap between adjacent windings and creating sufficient space for the transverse wire to be extracted without damage to the belt or wire.
Solution Approach 2:
The compression step is performed as a preliminary action before wire extraction. By pre-compressing the belt to expand the spiral windings, the subsequent wire extraction becomes straightforward and eliminates the need for complicated procedures such as incising the belt or applying lubricants.
2Productivity
If conventional extraction methods are used, then the transverse wire can be removed, but additional steps (incising, lubricant application) are required
Solution Approach 1:
Compression changes the geometric parameters of the spiral structure by expanding the windings outward. This parameter change creates immediate space for wire extraction, eliminating the need for time-consuming steps like incising the belt coating or applying and waiting for lubricant to take effect.
Solution Approach 2:
The patent extracts the transverse wire directly through the compressed spiral structure. The compression creates a clear extraction path through the expanded windings, allowing the wire to be pulled out in one straightforward motion without removing belt material or applying additional substances.
3Reliability
If the transverse wire is extracted without compression, then the belt structure remains intact, but the wire extraction becomes extremely difficult and damaging
Solution Approach 1:
Compression temporarily changes the density and spacing parameters of the spiral windings. The windings expand outward under compression, creating space for wire extraction while maintaining the overall structural integrity of the belt. Once compression is released, the spirals return to their original compact configuration.
Solution Approach 2:
The patent introduces a dynamic element to the extraction process by applying and releasing compression force. The spiral structure is dynamically transformed from a compact state (difficult to extract wire) to an expanded state (easy to extract wire), and then back to the compact state after wire removal, ensuring belt integrity throughout the process.

AI summary
