Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Switching of the access point wirelessly connected to the terminal causes instantaneous interruption in wireless communication.
Innovation Solution
A terminal apparatus with multiple wireless signal processing units and a control unit that manages connections to multiple shared access points, enabling seamless switching between them without interruption by controlling the connection destinations based on notifications from a sharing access point.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a terminal switches between access points to maintain wireless connection, then connection continuity is improved, but instantaneous interruption occurs during switching
Solution Approach 1:
The terminal performs preliminary actions by establishing wireless links with multiple shared access points before switching is needed. The control unit maintains connection destinations for multiple wireless signal processing units, enabling seamless switching by having backup connections ready in advance, thus avoiding interruption during actual switching operations
2Reliability
If multiple wireless links are maintained for seamless switching, then connection continuity is improved, but device complexity increases
Solution Approach 1:
Multiple wireless signal processing units are designed with universal functionality to handle different shared access points. Each unit can establish wireless links with any shared access point, allowing the system to maintain multiple connections without proportionally increasing complexity, as the units share common control logic and protocols

AI summary
A terminal apparatus is a terminal apparatus including a sharing access point, a plurality of shared access points, and a terminal apparatus. The terminal apparatus includes a plurality of wireless signal processing units and a control unit. The plurality of wireless signal processing units respectively transmits wireless signals using different channels. The control unit controls connection destinations of the plurality of wireless signal processing units. Each wireless signal processing unit establishes a wireless link with each shared access point. The control unit controls the connection destination of each wireless signal processing unit by enabling up to one of wireless links with the respective shared access points for each wireless signal processing unit and disabling the other wireless links on a basis of a notification from the sharing access point.
