Hybrid Conductor Loop Diagonal Orientation for Conveyor Belt Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conveyor belt conductor loops in existing technologies are prone to corrosion, have low flexibility, and short service life due to their susceptibility to mechanical stress, leading to false alarms from damaged loops without actual slits, especially after prolonged use.
Innovation Solution
A hybrid conductor loop with a flattened conductor cross section and a diagonal orientation within the conveyor belt, utilizing a textile core and a corrosion-resistant metallic sheath, increases the distance between transmitter and receiver, reducing electrical resistance and enhancing flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a metallic conductor loop is used in the conveyor belt, then electrical conductivity is achieved for detecting longitudinal slits, but the conductor loop becomes prone to corrosion and has reduced service life
Solution Approach 1:
The patent applies composite materials by combining textile material and metallic material in a hybrid conductor loop. The textile material serves as the core providing flexibility and mechanical strength, while the metallic material forms a corrosion-resistant sheath around it. This composite structure leverages the advantages of both materials: the textile provides durability and flexibility, while the metallic sheath provides electrical conductivity and corrosion resistance, thereby resolving the contradiction between reliability and corrosion susceptibility.
2Ease of operation
If a conventional circular conductor loop is used, then electrical conductivity is maintained, but flexibility and resistance to mechanical stress are reduced
Solution Approach 1:
The patent applies parameter changes by modifying the geometric parameters of the conductor loop. Specifically, it transitions from a conventional circular cross-section to a flattened cross-section with specific dimensional ratios (width to height ratio of 1.5:1 to 3:1). This geometric parameter change enhances the conductor loop's flexibility and ability to withstand mechanical stress during conveyor belt operation, while maintaining adequate electrical conductivity through the flattened metallic sheath structure.
3Measurement precision
If the transmitter and receiver are positioned close together, then detection sensitivity is high, but false alarms increase due to direct signal reception
Solution Approach 1:
The patent applies dimensionality change by introducing a diagonal orientation of the hybrid conductor loop relative to the conveyor belt's longitudinal direction. This angular arrangement (forming a diagonal rather than parallel alignment) creates a geometric relationship that prevents direct signal transmission between transmitter and receiver while maintaining detection sensitivity through the conductor loop's electromagnetic interaction with the belt structure, thereby reducing false alarms.

Function Achieved in This Case
The solution reduces electrical resistance and increases the distance between transmitter and receiver, preventing false alarms and extending the service life of the conveyor belt by improving the hybrid conductor loop's durability and flexibility.

AI summary
A conveyor belt has a carrying side cover plate and a running side cover plate each of a polymer material having elastic properties. The conveyor belt defines a conveyor belt longitudinal direction (X) and has an embedded reinforcement and at least one of the cover plates is provided with a hybrid conductor loop. The hybrid conductor loop communicates in a contactless manner with an interrogation station in the form of a transmitter/receiver pair. The hybrid conductor loop has a flattened conductor cross section and runs in the conveyor belt obliquely at an angle (α) relative to the conveyor belt transverse direction (Y) to form a diagonal direction (Z). The transverse direction (Y) is at right angles to the longitudinal direction (X). The arrangement of the transmitter/receiver pair is adapted to the diagonal direction (Z) to so increase the mutual spacing of the transmitter and the receiver.
