Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for testing capacitive touch screens are not reliable or repeatable when evaluating the use of gloves, as they fail to accurately simulate the interaction between a user's gloved finger and the screen, leading to inconsistent results.
Innovation Solution
A device comprising a conductive gauge and a non-conductive simulation plate of varying thickness and material, simulating different types of gloves, is used to test the compatibility of gloves with capacitive surfaces, allowing for repeatable validation of glove usage by mimicking the interaction with the screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a capacitive screen is used to detect finger touch, then the user experience is improved with simple touch without pressure, but the screen fails to detect touch when the user is wearing gloves due to insufficient electrical conductivity
Solution Approach 1:
The patent introduces a conductive layer as an intermediary between the capacitive screen and the gloved finger. This conductive layer compensates for the insufficient electrical conductivity of gloves by providing an additional conductive path, allowing the screen to detect the touch gesture even when the user is wearing non-conductive or low-conductivity gloves.
2Ease of manufacture
If existing test methods are used to validate glove compatibility, then the testing process is simple, but the test results are not repeatable or reliable
Solution Approach 1:
The patent creates a controlled test environment by using a test object that replicates the electrical characteristics of a gloved finger. This includes a conductive element covered with material having specific electrical conductivity, capacitance, and thickness parameters that match typical glove properties. This standardized copy enables repeatable and reliable testing across different glove types and testing sessions.
Solution Approach 2:
The patent systematically varies key parameters such as electrical conductivity, capacitance, and thickness of the test object to simulate different glove materials and conditions. By controlling and adjusting these parameters, the testing method can validate compatibility across a range of glove types while maintaining repeatable results through precise parameter specification.
