Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a mechanism to present information stored in a contactless type IC card to a user without the need for an external device, while overcoming the challenge of a restricted size for the input and output interface, which can inhibit contactless short-range wireless communication.
Innovation Solution
An information processing apparatus and method that includes a display unit and separate sensor elements, allowing the display unit to switch between output screens based on user input, with screens having different hierarchical levels, enabling direct switching between levels and appropriate information presentation despite a restricted interface size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an input and output interface such as LCD or touch panel is provided in the contactless type IC card, then information stored in the card can be presented to the user, but the size of the interface is restricted due to the small terminal size
Solution Approach 1:
The patent introduces a hierarchical navigation system that adds a temporal dimension to information presentation. Instead of expanding the spatial interface area, the system organizes information across multiple hierarchical levels (first level, second level, etc.) that users can navigate through time-based interactions with sensor elements, effectively presenting comprehensive information within a limited spatial footprint.
Solution Approach 2:
The patent segments information into multiple hierarchical levels and separates input functions from display functions. Sensor elements are positioned separately from the display unit, with each sensor element corresponding to specific navigation functions. This segmentation allows the interface to maintain a compact form while providing comprehensive information access through structured hierarchical navigation.
2Device complexity
If sensor elements are integrated with the display unit, then the interface can be compact, but user input detection may interfere with contactless short-range wireless communication
Solution Approach 1:
The patent extracts the sensor elements from the display unit and positions them separately. This spatial separation removes the source of electromagnetic interference from the communication area, allowing contactless short-range wireless communication to proceed without disruption while still enabling user input detection through the separately positioned sensor elements.
Solution Approach 2:
The patent introduces control unit logic as an intermediary that processes sensor inputs and manages display updates without requiring direct integration between sensor elements and display unit. This intermediary processing layer allows the system to maintain functional connectivity while preserving physical separation, thereby preventing electromagnetic interference with communication functions.
