Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In short distance wireless communication systems using electric field or magnetic field coupling, there is an issue with unintended data communication between devices in close proximity, leading to potential data theft or unauthorized data transfer without user knowledge.
Innovation Solution
A communication apparatus with a display unit, storage unit, and communication control unit that sets and enforces display instructions, including non-display instructions to restrict data communication, using electric field or magnetic field coupling, thereby controlling connection establishment and data exchange based on user-defined conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If short distance wireless communication based on electric field coupling or magnetic field coupling is used, then communication is only possible when devices are in close proximity, but unintended data communication and data theft can still occur without user knowledge
Solution Approach 1:
The system performs preliminary authentication and user confirmation actions before establishing data communication. The display unit shows communication requests and requires user approval, preventing unintended data communication before it can occur
Solution Approach 2:
The display unit provides visual feedback to users about communication requests, allowing users to consciously control and approve data exchange. This feedback mechanism ensures users are aware of and can prevent unintended communication
2Reliability
If display unit functionality is utilized to manage communication permissions, then communication control is improved, but device complexity increases
Solution Approach 1:
The display unit, which already exists in the device for other purposes, is given the additional function of displaying communication requests and controlling communication permissions. This multi-functional use avoids adding separate dedicated hardware for communication control
Solution Approach 2:
The system uses its own existing display capability to manage its communication security, rather than requiring external or separate control mechanisms. The device self-regulates communication permissions through its built-in display unit

AI summary
A communication apparatus is provided including a display unit, a storage unit capable of storing therein display condition information in which a display instruction for causing the display unit to perform display processing or a non-display instruction for not allowing the display unit to perform the display processing is set, and a short distance wireless communication control unit for controlling a connection establishment communication with a communication party by a communication system based on electric field coupling or magnetic field coupling and data communication with the communication party by the communication system. The short distance wireless communication control unit judges whether the non-display instruction is set in the display condition information stored in the storage unit, and does not make the data communication with the communication party when judging that the non-display instruction is set, the communication control unit.
