Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods fail to accurately predict the degradation of surfaces over time due to stress from normal use, lacking a controlled and efficient means to simulate service and cleaning conditions independently.
Innovation Solution
An apparatus comprising a service assembly for applying dirt or scuffing, and a cleaning assembly for scrubbing or burnishing, allowing for controlled exposure to stress conditions, with optional computer-programmed control and linear movement of the surface for testing surface durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a surface is exposed to normal use conditions for a long period to observe degradation, then the accuracy of durability prediction is improved, but the time required for testing increases significantly
Solution Approach 1:
The patent applies parameter changes by intensifying the stress conditions during testing. Instead of exposing the surface to normal use conditions at standard intensity, the apparatus applies accelerated stress through multiple passes of dirt application, scuffing, and cleaning operations. This changes the parameters of the stress application to achieve rapid degradation that mirrors long-term normal use, allowing accurate durability predictions to be made in a fraction of the time required for actual long-term exposure testing.
2Measurement precision
If existing testing methods are used to assess surface durability, then the simplicity of the testing process is maintained, but the ability to predict long-term degradation accurately is compromised
Solution Approach 1:
The patent applies segmentation by dividing the testing apparatus into distinct functional assemblies: a dirt application assembly, a scuffing assembly, and a cleaning assembly. Each assembly performs a specific function in simulating service conditions. This segmentation allows the complex testing process to be broken down into manageable, controllable operations that can be independently adjusted and optimized for accurate durability prediction.
Solution Approach 2:
The patent applies universality by designing the testing apparatus to perform multiple functions within a single integrated system. The apparatus can apply dirt, scuff the surface, and perform cleaning operations sequentially or independently, providing comprehensive simulation of various service conditions. This multi-functionality enables accurate prediction of long-term degradation while maintaining a unified, manageable testing system rather than requiring multiple separate simple tests.
3Measurement precision
If service and cleaning conditions are tested simultaneously, then the completeness of durability assessment is improved, but the control over individual conditions becomes difficult
Solution Approach 1:
The patent applies segmentation by separating the testing apparatus into independent service assembly and cleaning assembly components. The service assembly includes dirt application and scuffing mechanisms, while the cleaning assembly includes scrubbing and burnishing mechanisms. This segmentation allows each assembly to be controlled and adjusted independently, providing complete assessment of both service and cleaning effects while maintaining easy control over individual test conditions through separate control systems for each assembly.
