Endless Belt Binder for Carcass Cord Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Endless elastomeric belts used in hay balers face challenges in maintaining the selected arrangement of carcass cords during manufacturing and curing, which can lead to cord misalignment and potential belt failure due to debris catching on outer ends.
Innovation Solution
The belts feature carcass cords wound in multiple turns around the circumference with an elongate binder extending transversely around the lateral edges, maintaining cord alignment and protecting outer ends from debris, and are embedded in an elastomeric matrix with transverse layers for enhanced durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If carcass cords are arranged in multiple turns around the circumference, then cord alignment and belt stability are improved, but manufacturing complexity increases
Solution Approach 1:
The binder is applied to the carcass cords before the belt curing process to maintain cord alignment and prevent misalignment during manufacturing and curing operations
Solution Approach 2:
The binder acts as an intermediary element between the carcass cords and the elastomeric matrix, holding the cords in their proper positions during the manufacturing process
2Ease of manufacture
If outer ends of carcass cords are exposed, then cord installation is simplified, but reliability decreases due to debris catching
Solution Approach 1:
The binder covers the previously exposed outer ends of the carcass cords, converting the harmful effect of debris catching into a protected configuration where the binder itself shields the cord ends
3Manufacturing precision
If binder is added to maintain cord arrangement, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The binder serves multiple functions: it maintains cord alignment during manufacturing, protects cord ends from debris, and reinforces the overall belt structure, thereby justifying the added complexity through multi-functionality

AI summary
An endless elastomeric belt includes a carcass that includes an elastomeric matrix extending in an endless loop around a circumference of the belt. The matrix has opposite lateral edges defining a width of the matrix, and a carcass cord within the matrix extending in multiple turns around the circumference of the belt. An elongate binder extends around the lateral edges of the matrix generally transverse to the centerline of the body.
