Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The inconsistency in testing results for portable devices due to variations in operator size, pressure, and technique makes it challenging to reliably diagnose and confirm user interface malfunctions, particularly in devices with tactile and touch-responsive components.
Innovation Solution
A testing assembly comprising a base with a molded pattern to securely hold the device, a top mold with access holes defining a test pattern, and a stylus for consistent contact, allowing for precise and repeatable testing of buttons and touch-responsive surfaces, ensuring that different operators achieve similar results.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual testing is performed by operators, then testing can be conducted on portable devices, but test results are inconsistent due to variations in operator size, pressure, and technique
Solution Approach 1:
The patent introduces a template with access holes as an intermediary between the operator and the device interface. This template standardizes the testing process by providing predetermined access holes that guide the stylus to specific locations, eliminating variations caused by different operator techniques, hand sizes, and pressure applications. The template acts as a mediator that translates manual testing operations into consistent, repeatable actions.
Solution Approach 2:
The template creates a standardized copy or representation of the device interface layout through its access holes. Rather than requiring operators to directly interact with the device, the template provides a replicated testing pattern that can be consistently applied across different devices and operators, ensuring uniform testing conditions.
2Adaptability or versatility
If operators use varying pressure and techniques, then different testing approaches can be attempted, but this leads to variability in test outcomes
Solution Approach 1:
The template provides different local qualities through its access holes - each hole is positioned at a specific location with a predetermined size and shape. This allows the testing system to apply localized, standardized pressure and contact points at each interface element, ensuring consistent measurement precision while maintaining the ability to test different locations across the device interface.
3Ease of operation
If operators manually test interface elements, then direct interaction with buttons and touch surfaces is possible, but results vary based on hand size and operator characteristics
Solution Approach 1:
The template serves as a precision intermediary that decouples the operator's hand characteristics from the actual testing locations. The access holes in the template are manufactured with precise dimensions and positions, ensuring that the stylus contacts the device interface at exact, repeatable locations regardless of the operator's hand size or natural positioning variations.

AI summary
An apparatus is disclosed for testing portable devices. The apparatus includes a base upon which the portable device is mounted, and a top mold which fits over the base to immobilize the portable device. Templates can also be formed on the top mold or base. The templates contain test patterns that are defined by a plurality of apertures. A stylus is used to test the portable device by engaging or contacting different locations through the apertures in the test pattern.
