Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wireless terminal devices autonomously perform routing in a wireless ad hoc network, then the network can be instantly constructed without fixed infrastructure, but the time to detect and respond to communication route abnormalities becomes lengthy
Solution Approach 1:
The communication device preliminarily establishes a communication route through one or more wireless terminal devices before actual communication begins. This pre-established route enables immediate communication upon network construction while providing a baseline for future abnormality detection and route change decisions.
Solution Approach 2:
The system implements feedback by monitoring the state of communication signals along the established route. When the signal state deviates from predetermined rules or thresholds, the system automatically triggers route reconstruction, creating a closed-loop control mechanism that reduces abnormality detection time while maintaining network adaptability.
2Device complexity
If the communication device waits for notification from wireless terminal devices to detect abnormalities, then the routing process remains simple, but the time from abnormality occurrence to recognition becomes long
Solution Approach 1:
The communication device actively monitors communication signal states and compares them against predetermined rules. When deviations are detected, the system automatically initiates route reconstruction without waiting for notifications from wireless terminal devices, significantly reducing abnormality recognition time while maintaining manageable complexity through rule-based automated decision-making.
3Ease of manufacture
If the system uses predetermined rules for communication, then communication between devices can be standardized, but the ability to promptly detect and respond to route changes is reduced
Solution Approach 1:
The system monitors communication signal parameters (such as signal strength, quality, or presence) and compares them against predetermined thresholds. When parameters deviate from acceptable ranges, the system automatically triggers route reconstruction. This parameter-based approach maintains communication standardization through predetermined rules while enabling rapid response to route abnormalities through automated threshold-based detection.

AI summary
A master station 101 according to one aspect of the present invention includes: a communicating unit 10 that can communicate with a subordinate station 102 by using a communication route through one or a plurality of wireless terminal devices 202, and communicates with the subordinate station 102 in accordance with a predetermined rule; and a reconstruction processing unit 43 that performs a process of changing the communication route when a state against the predetermined rule occurs. The reconstruction processing unit 43 decides whether to perform the process of changing the communication route, based on an arrival state of a communication signal destined for the own master station 101 regularly transmitted from the subordinate station 102.
