Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for attaching connector elements to conveyor belt ends are either complex or risk a temporary, doughy adhesive bond, leading to potential misalignment and instability during the attachment process.
Innovation Solution
A method using a connector element with a base layer and adhesive layer, where the adhesive layer is activated by heat and reinforced with a cooled pressing device to ensure a firm bond, combined with a positioning device for precise alignment and attachment, allowing for a metal-free and secure connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a heated pressing device is used to activate the adhesive layer, then the adhesive bond strength is improved, but the bond remains temporary and doughy during the attachment process, risking misalignment
Solution Approach 1:
The patent applies preliminary action by using a positioning device to pre-align the connector element with the belt end before the adhesive bond becomes fully firm. The positioning device maintains the correct spatial relationship during the adhesive curing process, preventing misalignment that would occur if only heating were used without preliminary positioning.
Solution Approach 2:
The positioning device acts as an intermediary between the connector element and the belt end, maintaining their relative positions during the adhesive bonding process. This intermediary mechanism ensures alignment stability while the adhesive transitions from a doughy state to a firm bond.
2Strength
If wire hooks are used to penetrate the belt, then mechanical connection is achieved, but the attachment process becomes complex and time-consuming
Solution Approach 1:
The patent replaces the mechanical wire hook penetration system with a thermal adhesive bonding system. Instead of mechanically penetrating the belt with wire hooks, the adhesive layer is heated to activate bonding, significantly simplifying the attachment process and increasing productivity while maintaining connection strength.
Solution Approach 2:
The patent changes the bonding mechanism from mechanical (wire hooks) to thermal (heated adhesive). By changing the physical parameter of the adhesive from cold to heated state, the bonding process becomes faster and simpler while achieving equivalent or superior connection strength.
3Manufacturing precision
If the connector element is positioned before adhesive bonding, then alignment precision is improved, but the connector element may shift during the bonding process when the adhesive is not yet firm
Solution Approach 1:
The positioning device performs preliminary alignment of the connector element with the belt end before adhesive bonding begins. This preliminary positioning ensures precise alignment is achieved before the adhesive is applied and heated, establishing the correct spatial relationship from the start.
Solution Approach 2:
The positioning device provides beforehand cushioning by maintaining the aligned position of the connector element during the entire adhesive bonding process. It prevents shifting that would occur due to the doughy state of the adhesive, ensuring position stability throughout the critical bonding phase.
