Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current chip detection systems in mechanical systems, such as gearboxes, struggle to effectively and non-destructively verify the functionality of chip collectors in detecting ferrous or conductive particles, which indicates impending component failure, especially in complex power transmission mechanisms used in vehicles and industrial machinery.
Innovation Solution
A method and apparatus involving the injection of a slurry containing conductive metal chips and lubricant into the mechanical system during operation, allowing the chips to flow through the system and be detected by chip detectors, simulating component failure while minimizing damage, and determining the detection time and threshold to assess the system's effectiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conductive chips are injected into the mechanical system to test chip detection capability, then the detection effectiveness can be verified, but the mechanical components may suffer damage from the injected chips
Solution Approach 1:
The patent uses inexpensive, sacrificial conductive chips specifically for testing purposes. These test chips are intentionally disposable and meant to be consumed during the detection verification process, allowing repeated testing without concern for damage to valuable components.
Solution Approach 2:
The patent introduces an intermediary testing medium (slurry containing conductive particles in lubricant) that facilitates the detection test while minimizing direct harm. This intermediary substance allows verification of chip detector functionality without requiring actual component failure.
2Ease of manufacture
If the mechanical system is shut down to inject chips for testing, then injection can be performed, but the testing time and system availability are reduced
Solution Approach 1:
The patent enables periodic injection of test slurries through the injection tube during normal system operation. This allows detection capability verification to occur in periodic intervals without requiring complete system shutdown, maintaining operational availability while enabling regular testing.
Solution Approach 2:
The injection tube is pre-installed in the machinery casing during manufacturing, with the injection port positioned to deliver chips directly into the lubricant flow path. This preliminary preparation allows testing to be performed quickly during operation without complex setup procedures.
3Reliability
If chip detectors are installed in the mechanical system, then component failure can be detected early, but the system complexity increases
Solution Approach 1:
The chip detectors serve multiple functions: they detect conductive chips from actual component wear during normal operation, and they detect injected test chips during verification testing. This multi-functionality reduces the need for separate testing equipment and simplifies the overall system architecture.
Solution Approach 2:
The existing chip detection system performs self-verification by detecting the injected test chips. The same detection mechanism used for monitoring operational wear also validates its own functionality through the test slurry injection, eliminating the need for separate verification systems.
4Measurement precision
If actual component failure is allowed to generate chips for testing, then realistic detection scenarios are created, but the mechanical components are destroyed
Solution Approach 1:
The patent creates artificial copies of actual wear chips by injecting conductive particles that simulate the size, shape, and electrical properties of real wear debris. These test chips replicate the detection scenario without requiring actual component failure, maintaining measurement realism while preserving component integrity.
