Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conveyor device band replacement is a time-consuming and difficult process due to narrow spaces between rollers and sides, often resulting in equipment damage and user injuries, requiring specialized technicians and prolonged replacement times.
Innovation Solution
A band replacement tool with a shaft of sufficient length and narrow width to fit between rollers and sides, featuring a U-shaped head to cup the band and a handle with finger grips for secure installation, allowing quick and safe band replacement without damaging equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a standard replacement method is used, then the band can be replaced, but the process is time-consuming and difficult due to narrow spaces between rollers and sides
Solution Approach 1:
The patent introduces a specialized tool as an intermediary device to perform the band replacement task. The tool includes a shaft with a narrow profile that fits between the roller and side member, and a head with a cup-shaped depression that engages with the band. This intermediary tool enables users to easily guide and push the band onto the roller without direct manual manipulation in the narrow space, resolving both the time-consuming nature and the difficulty of the replacement process.
Solution Approach 2:
The replacement tool is segmented into distinct functional components: a shaft portion for accessing the narrow space between the roller and side member, and a head portion with a cup-shaped depression for engaging the band. This segmentation allows each part to perform its specific function optimally - the shaft reaches into the constrained space while the head provides the necessary engagement surface for manipulating the band, thereby improving both ease of operation and replacement speed.
2Reliability
If users manually push the band back into place, then replacement is possible, but equipment damage and user injuries may occur
Solution Approach 1:
The tool serves as a safe intermediary between the user and the band/roller system. The shaft with its narrow profile allows the user to work from outside the hazardous narrow space, while the head with its cup-shaped depression provides controlled engagement with the band. This eliminates the need for users to reach into the narrow space between rollers and sides, preventing both equipment damage and user injuries while ensuring reliable replacement.
Solution Approach 2:
The cup-shaped head of the tool is designed to cradle and control the band during the replacement process, preventing the band from slipping or snapping back unexpectedly. This beforehand control mechanism cushions against potential hazards by maintaining secure engagement with the band throughout the installation process, thereby preventing equipment damage and user injuries before they can occur.
3Manufacturing precision
If specialized technicians are used for band replacement, then proper installation is achieved, but the process becomes more complex and time-consuming
Solution Approach 1:
The specialized tool acts as an intermediary that encapsulates the expertise previously required from trained technicians. The tool's design - with its specifically dimensioned shaft that fits the narrow space and its cup-shaped head that properly engages the band - embeds the correct installation technique into the tool itself. This allows any user to achieve proper installation quality without requiring specialized training, thereby maintaining manufacturing precision while reducing device complexity.
Solution Approach 2:
The tool is designed to be self-guiding and self-explanatory in its operation. The shaft's narrow profile automatically guides it into the correct position between the roller and side member, and the cup-shaped head naturally engages with the band in the proper orientation. This self-service design eliminates the need for complex procedures or specialized technician knowledge, allowing users to achieve high-quality installation independently and reducing the overall complexity of the replacement process.

AI summary
Examples provide a band replacement tool for installing a band around a set of rollers on a conveyor device. The band replacement tool includes a shaft having a minimum threshold length sufficient to reach a lower roller on the conveyor device. The shaft has a maximum threshold width which enables the shaft of the tool to fit between rollers. The shaft is sized to fit within a narrow space between the last roller and the side of the conveyor device. The head of the tool is a concave shape having two side members substantially parallel to each other forming a U-shaped end. The head is sized to partially cup a portion of a band during installation. The handle optionally includes finger grips and is shaped to increase leverage enabling faster installation of the band over the rollers. An opening is optionally disposed within the handle for hanging the tool.
