Settlement Terminal Device with Integrated Tamper-Resistant Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing settlement terminal devices lack robustness and operability when combining secured and non-secured portions, as they are prone to tampering and do not provide a clear distinction between secure and non-secure input areas, compromising both security and user experience.
Innovation Solution
A settlement terminal device design featuring a first user interface for non-secure operations and a second tamper-resistant user interface, both integrated within a housing with a light transmitting member covering their surfaces, ensuring robustness and clear separation of secure and non-secure input areas, enhancing both security and usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a secured portion and a non-secured portion are combined in a hybrid configuration, then tamper resistance is improved, but robustness (falling impact resistance) deteriorates
Solution Approach 1:
The patent merges the secured portion (second information processor) and non-secured portion (first information processor) into a single integrated housing structure. This unified design allows the entire device to benefit from the robustness of the housing while maintaining internal separation for security purposes, resolving the contradiction between tamper resistance and falling impact resistance
2Reliability
If a secured portion and a non-secured portion are combined in a hybrid configuration, then tamper resistance is improved, but operability deteriorates
Solution Approach 1:
The patent introduces a light transmitting member as an intermediary element that covers both the secured and non-secured user interfaces. This mediator provides visual distinction between secure and non-secure input areas while maintaining a unified appearance, allowing users to easily identify which area to use for different operations without compromising security
3Ease of operation
If a light transmitting member covers both user interfaces, then operability is improved, but security deteriorates
Solution Approach 1:
The light transmitting member utilizes optical properties (transparency/translucency) to create visual differentiation between the secured and non-secured input areas. This allows users to distinguish between secure and non-secure zones through light interaction, maintaining security while improving ease of operation
