Motion State Monitoring System Sensor Attaching Direction Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motion state monitoring systems cannot manage measurement results separately for each attaching direction of a sensor, as the connection direction of the sensor with respect to the axial direction of a band is fixed, limiting flexibility and accuracy.
Innovation Solution
A motion state monitoring system that includes an acquisition unit, an attaching direction detection unit, and a control processing unit to detect and manage the attaching direction of the sensor, allowing for flexible attachment and accurate data management by associating sensing information with the attaching direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the sensor connection direction is fixed to the axial direction of the band, then the system structure is simple, but the sensor cannot be freely attached and measurement results cannot be managed separately for each attaching direction
Solution Approach 1:
The system performs preliminary detection of the sensor's attaching direction before measurement begins. The attaching direction detection unit detects the actual attaching direction of the sensor, and this information is stored and used throughout the measurement process to properly associate and manage measurement results according to their specific attaching directions.
Solution Approach 2:
The system adds a new dimension of data management by incorporating attaching direction information as an additional parameter. Instead of simply storing measurement values, the system now manages data in association with attaching direction, effectively adding a categorical dimension to the measurement data structure that enables separate management for different attaching directions.
2Ease of operation
If the sensor is attached with clothing or adhesive surface interposed, then the attachment is more comfortable, but the connection direction becomes uncertain and measurement results cannot be managed by attaching direction
Solution Approach 1:
The system implements feedback by continuously detecting the sensor's attaching direction during the measurement process. The attaching direction detection unit provides real-time feedback on the actual attaching direction, which is then used to correctly associate measurement results with their corresponding attaching directions, ensuring accurate data management even when the sensor is attached through clothing or adhesive surfaces.
Solution Approach 2:
The sensor system performs self-service by automatically detecting its own attaching direction without requiring external intervention or manual configuration. The attaching direction detection unit within the sensor system autonomously determines the attaching direction and provides this information to the measurement result management system, eliminating the need for manual direction specification by the user.
