Rubber-Embedded Sensor Layout for Accurate Ambient Sensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rubber products with sensors for moving applications are costly and provide limited information about ambient environmental values, and existing sensor arrangements are not optimally designed for accurate and efficient measurement of these values.
Innovation Solution
A rubber product with a sensor protruding from its outer surface, preferably an RFID sensor combining temperature and humidity sensing, is integrated into the rubber product, allowing for precise measurement of ambient values while being protected from environmental conditions, with additional internal sensors for error correction and simple signal output.

Engineering Contradiction Analysis
1Object-affected harmful factors
If the sensor is completely enclosed in the rubber product, then the sensor is protected from environmental conditions, but the measurement of ambient values is impaired
Solution Approach 1:
The sensor is divided into two functional zones: an enclosed region for protection and a protruding region for measurement. This segmentation allows the sensor to simultaneously benefit from protection while maintaining measurement capability through the exposed portion.
Solution Approach 2:
Different regions of the sensor have different properties: the main body is enclosed for protection while specific sensing elements protrude for measurement. This local differentiation of quality enables simultaneous protection and measurement functionality.
2Measurement precision
If the sensor protrudes from the outer surface, then the measurement of ambient values is improved, but the sensor is exposed to environmental damage
Solution Approach 1:
The sensor structure is segmented into protected and exposed zones, allowing the measurement elements to protrude while the majority remains enclosed for protection.
Solution Approach 2:
The sensor has differentiated local properties where specific sensing regions are exposed for measurement while other regions remain enclosed for protection, optimizing both measurement and protection simultaneously.
3Loss of information
If multiple sensors are integrated into the rubber product, then the information value about ambient conditions is enhanced, but the device complexity increases
Solution Approach 1:
Multiple sensor functions (temperature, humidity, pressure) are merged into a single integrated sensor module that is collectively enclosed in the rubber product, reducing individual component complexity while maintaining comprehensive measurement capability.
Solution Approach 2:
The integrated sensor module provides multiple measurement functions simultaneously, making the system more information-rich without proportionally increasing complexity, as the sensors work together as a unified multi-functional unit.
4Stability of the object's composition
If the sensor is integrated into the rubber product, then the structural integrity is maintained, but the cost of manufacturing increases
Solution Approach 1:
The sensor is integrated into the rubber product during the molding process itself, rather than as a post-manufacturing assembly step. This preliminary integration maintains structural integrity while avoiding the need for separate mounting operations, potentially reducing overall manufacturing complexity.
