Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If pressure sensor pads are embedded in a backrest cushion to detect sitting posture, then posture detection capability is provided, but the system cannot provide timely and effective feedback to improve posture
Solution Approach 1:
The patent implements a feedback mechanism where the controller receives detection data from pressure sensors, classifies posture states, and provides feedback to the user through appropriate outputs. This closed-loop feedback system enables the apparatus to not only detect posture accurately but also to respond effectively by prompting users to correct their posture, thereby resolving the contradiction between detection capability and feedback effectiveness.
2Measurement precision
If multiple sensors are used to classify user posture accurately, then measurement precision improves, but device complexity increases
Solution Approach 1:
The backrest cushion is divided into multiple pressure sensor pads arranged in a segmented pattern. Each sensor pad independently detects pressure at its specific location, and the controller integrates these segmented detection data points to classify overall posture. This segmentation approach enables accurate posture detection while keeping individual sensor elements simple and manageable.
Solution Approach 2:
The pressure sensor pads serve multiple functions: they detect pressure magnitude, determine pressure distribution patterns, and enable classification of various posture states (sitting, reclining, lying down). This multi-functionality of the sensor array reduces the need for additional specialized sensors, thereby controlling device complexity while maintaining high measurement precision.
