Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If force sensing elements are used for pressure mapping, then force measurement capability is provided, but measurement precision deteriorates in varying environmental conditions
Solution Approach 1:
The patent combines force sensing elements with environmental sensing elements (temperature, humidity sensors) into an integrated smart insole system. The environmental sensors detect varying environmental conditions and this data is used to compensate for their effect on force sensing element measurements, thereby maintaining measurement precision across different environments while preserving measurement reliability.
Solution Approach 2:
The system implements feedback by using environmental sensing elements to monitor temperature and humidity conditions, then using this information to adjust and compensate force measurements from the force sensing elements. This feedback mechanism ensures that measurement precision is maintained even when environmental conditions vary, while the overall measurement reliability is preserved through the integrated sensing approach.
2Adaptability or versatility
If multiple sensing elements are integrated, then measurement capability is improved, but device complexity increases
Solution Approach 1:
The smart insole system is designed with multi-functional sensing elements that can detect various physical quantities (force, pressure, temperature, humidity) using a unified integrated platform. This universal approach allows the system to perform multiple sensing functions simultaneously, improving adaptability and versatility while managing device complexity through a consolidated sensor array rather than separate independent systems.
Solution Approach 2:
The patent divides the sensing functionality into distinct sensing elements (force sensing elements, environmental sensing elements) that are segmented and distributed across the insole structure. Each sensing element type is positioned strategically to detect specific parameters, allowing the system to achieve comprehensive measurement capability while maintaining manageable complexity through functional segmentation and modular integration.
