Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the polymer matrix is coated individually on each optical waveguide in situ, then the luminescent compound can be immobilized in the sensing region, but the process becomes slow, labor-intensive, and error-prone, reducing productivity and reliability

Engineering Contradiction:
Improvesensor functionalityVSAvoidmanufacturing speed
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The invention separates the polymer coating process from the optical waveguide, instead coating multiple substrates simultaneously in a batch process. This segmentation allows parallel processing of multiple sensors, dramatically increasing productivity while maintaining reliable luminescent compound immobilization through the standardized coating procedure

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The polymer matrix with immobilized luminescent compound is pre-coated onto substrates before assembly with the optical waveguide. This preliminary action allows the coating to be performed under controlled conditions in a batch process, ensuring consistent quality and eliminating the need for individual in situ coating of each assembled sensor

Inventive Principle:
Principle #10Preliminary action

2Ease of manufacture

If the polymer is coated individually on each optical waveguide, then the sensing region can be formed, but uniformity of the sensing region cannot be guaranteed, requiring individual calibration of each sensor

Engineering Contradiction:
Improvecoating process simplicityVSAvoidsensing region uniformity
Core Design Contradiction:
Ease of manufactureVSManufacturing precision

Solution Approach 1:

Multiple substrates are coated simultaneously in a single batch process rather than individually. This merging of coating operations ensures that all substrates receive identical coating conditions, resulting in uniform polymer matrix thickness and luminescent compound distribution across all sensing regions, thereby improving manufacturing precision without complicating the process

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If individual coating of optical waveguides is performed, then the luminescent compound can be immobilized, but excess polymer solution must be prepared, causing wastage of expensive luminescent compounds

Engineering Contradiction:
Improveluminescent compound immobilizationVSAvoidluminescent compound wastage
Core Design Contradiction:
ReliabilityVSLoss of substance

Solution Approach 1:

Instead of preparing excess polymer solution for each individual coating, the invention uses a controlled batch coating process where the polymer solution is applied to multiple substrates simultaneously. This approach eliminates the need for excessive preparation while ensuring complete coverage of all substrates, thereby reducing wastage of expensive luminescent compounds while maintaining reliable immobilization

Inventive Principle:
Principle #16Partial or excessive action
