Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current devices for movement analysis and posture support lack effective feedback mechanisms to correct and monitor movement behavior, particularly in the torso area, and fail to provide real-time adjustments for optimal posture.
Innovation Solution
A device with a flexible support element and tensioning straps that cross in the back area, equipped with sensors to detect forces, deformations, angles, and accelerations, providing feedback through adjustable counterforces in the shoulder or chest area, and optionally incorporating sensors like conductive textile threads, gyroscopes, or accelerometers to record and evaluate movement states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a flexible support element with tensioning straps is used to support posture, then comfort and flexibility are improved, but the ability to provide real-time feedback and precise measurement is worsened
Solution Approach 1:
The patent combines the flexible support element with sensor systems (force sensors, deformation sensors, angle sensors, acceleration sensors) to integrate comfort functionality with measurement capability. The sensors are embedded within or attached to the flexible support structure, allowing simultaneous posture support and real-time data collection without compromising either comfort or measurement precision.
Solution Approach 2:
The patent introduces sensor systems as intermediaries between the flexible support element and the user's posture. These sensors detect physical quantities (forces, deformations, angles, accelerations) and convert them into measurable signals, enabling the flexible support structure to provide both mechanical support and precise measurement feedback.
2Measurement precision
If sensors are added to detect forces, deformations, angles and accelerations, then measurement precision is improved, but device complexity is worsened
Solution Approach 1:
The patent employs multi-functional sensor systems that can detect multiple physical quantities (forces, deformations, angles, accelerations) simultaneously using integrated sensor modules. This allows a single sensor system to perform multiple measurement functions, improving detection accuracy while minimizing the increase in device complexity compared to using separate sensors for each parameter.
Solution Approach 2:
The patent utilizes sensors that detect changes in physical parameters (force, deformation, angle, acceleration) and converts them into electrical signals for processing. By monitoring parameter changes rather than requiring complex mechanical measurement mechanisms, the system achieves high measurement precision with relatively simple sensor-based detection.
3Measurement precision
If tensioning straps are guided crossing in the back area to detect torsional movements, then measurement capability is improved, but ease of operation is worsened
Solution Approach 1:
The patent employs adjustable fastening devices that allow dynamic adjustment of the tensioning straps' attachment points on the carrier element. This enables the system to adapt to different users and measurement requirements, maintaining ease of operation while preserving the crossed strap configuration's ability to detect torsional movements through controlled tension and deformation.
