Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a sensor mat with multiple elements is used to ensure homogeneous contact with the body surface, then measurement precision is improved, but device complexity increases and cleaning becomes more time-consuming
Solution Approach 1:
The sensor mat is divided into multiple sensor elements arranged in a specific pattern, with each element contributing to the measurement. This segmentation allows homogeneous contact distribution across the body surface while maintaining manageable complexity through modular design
Solution Approach 2:
A contact layer is introduced as an intermediary between the sensor elements and the body surface. This contact layer ensures homogeneous contact distribution and simplifies the interface between the complex sensor array and the irregular body surface
2Measurement precision
If a sensor mat with multiple elements is used to ensure homogeneous contact with the body surface, then measurement precision is improved, but the time required for cleaning increases
Solution Approach 1:
The sensor mat is constructed as a flexible, thin-film structure that can conform to the body surface contours. This flexibility allows the entire mat to be easily removed and cleaned as a single unit, reducing cleaning time while maintaining homogeneous contact through the flexible contact layer
3Ease of operation
If adhesive elements are used to attach the sensor mat to the body surface, then ease of operation is improved, but measurement precision may be compromised due to uneven contact
Solution Approach 1:
Adhesive elements are strategically positioned at specific locations on the sensor mat rather than uniformly distributed. This local placement provides sufficient attachment while allowing the flexible contact layer to conform to the body surface, ensuring homogeneous contact in the measurement regions
Solution Approach 2:
A dedicated contact layer serves as an intermediary between the adhesive elements and the sensor elements. This layer distributes the attachment force uniformly while maintaining homogeneous contact conditions for the optical measurements
