Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Chain links in conveyor belt systems experience thermal stresses due to repeated heating and cooling, leading to premature failure and costly downtime, necessitating a tool for efficient and consistent testing for fatigue.
Innovation Solution
A chain link tester adapted for use with a torque metering device, such as a torque wrench or ratchet, to apply a consistent amount of torque to each chain link, facilitating the detection of signs of wear and fatigue by inserting between the chain links and sprocket, with features like tapered levers and sockets for precise alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual testing of chain links is performed without standardized torque application, then operator flexibility is maintained, but measurement precision and consistency deteriorate
Solution Approach 1:
The patent introduces a torque metering device as an intermediary between the operator and the chain link testing process. This device mediates the force application by providing standardized torque values through pre-calculated lever arm positions, ensuring consistent and precise torque application without requiring complex automated systems.
Solution Approach 2:
The patent implements preliminary action by pre-calculating and marking specific lever arm positions that correspond to predetermined torque values. This allows operators to apply exact torque levels simply by positioning the lever arm at the appropriate mark, eliminating the need for complex real-time calculations or control systems during testing.
2Reliability
If comprehensive testing of all chain links is performed, then detection reliability improves, but loss of time increases due to operator fatigue
Solution Approach 1:
The patent replaces the mechanical system of manual force estimation with a torque metering device that provides objective, standardized torque application. This substitution eliminates variability introduced by operator fatigue and maintains consistent testing quality throughout the entire inspection process, regardless of duration.
Solution Approach 2:
The patent uses the torque metering device to create a standardized, repeatable testing procedure that can be consistently applied to each chain link. By copying the same torque application method across all links, the system ensures uniform testing conditions that improve reliability while maintaining efficiency.
3Manufacturing precision
If tight tolerances are used for chain and sprocket dimensions, then system precision improves, but ease of operation deteriorates due to difficulty in alignment
Solution Approach 1:
The patent applies preliminary action by providing pre-calculated torque values and corresponding lever arm positions that account for the tight tolerances. This allows operators to work with precision-matched components without needing to perform complex alignment calculations, as the torque marks are predetermined based on the specific chain and sprocket configuration.
