Solution Overview
Problem
Existing short-range wireless communication systems consume excessive power due to continuous connectivity, especially when the measured physical quantity remains unchanged, requiring frequent user intervention for reconnection.
Innovation Solution
Implementing a system where communication devices autonomously disconnect and reconnect short-range wireless communication based on predetermined reconnection conditions, such as time or physical quantity changes, without user intervention, using time acquisition units and sensors to manage the disconnection and reconnection process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If short-range wireless communication is maintained continuously, then data transmission between sensor device and communication device is ensured, but power consumption increases excessively
Solution Approach 1:
The patent implements periodic disconnection and reconnection of wireless communication based on predetermined conditions (time intervals, physical quantity changes). Instead of continuous communication, the system periodically disconnects to save power and reconnects when conditions are met, transforming continuous action into periodic action to resolve the contradiction between reliability and power consumption.
2Use of energy by moving object
If wireless communication is disconnected to save power, then power consumption is reduced, but user intervention is required for reconnection which complicates operation
Solution Approach 1:
The patent enables the communication device and sensor device to automatically determine reconnection conditions and perform reconnection without user intervention. The devices monitor predetermined conditions (time, physical quantities) and autonomously initiate reconnection when conditions are satisfied, making the system self-serving and eliminating the need for manual user operations.
Solution Approach 2:
The system implements feedback mechanisms where devices monitor physical quantities (acceleration, angle, temperature) and time conditions, then use this feedback information to automatically determine when to reconnect. This closed-loop feedback control enables autonomous decision-making for reconnection, removing the need for user intervention.
3Productivity
If reconnection condition is set based on physical quantity changes, then unnecessary reconnections are prevented, but measurement precision requirements increase
Solution Approach 1:
The patent uses changes in physical quantity parameters (acceleration, angle, temperature) as triggers for reconnection decisions. By monitoring whether these parameters exceed predetermined thresholds or change beyond specified ranges, the system intelligently determines when reconnection is necessary, preventing unnecessary reconnections while utilizing readily measurable parameters.
