1Ease of manufacture

If conventional plastics are used for support structures, then ease of manufacture is improved, but heat resistance deteriorates causing deformation under high temperatures

Engineering Contradiction:
Improveease of manufactureVSAvoidheat resistance
Core Design Contradiction:
Ease of manufactureVSTemperature

Solution Approach 1:

The patent applies composite materials by combining polymer resin with carbon particles to create a carbon-filled polymer support structure. This composite material simultaneously provides heat resistance (withstanding temperatures up to 400°C or higher) and structural integrity, while maintaining ease of manufacture through molding processes. The carbon particles dispersed in the polymer matrix prevent deformation at high temperatures without complicating the manufacturing process.

If conventional heat resistant plastics are used for support structures, then heat resistance is improved, but fluorescence interference worsens affecting detection accuracy

Engineering Contradiction:

Core Design Contradiction:
TemperatureVSMeasurement precision

Solution Approach 1:

The patent converts the potential harm of fluorescence interference into a benefit by using carbon-filled polymer material that is inherently non-fluorescent. The carbon particles not only provide heat resistance but also eliminate fluorescence interference with chemical reporter detection. This material choice simultaneously achieves both heat resistance and detection accuracy, as the carbon-filled polymer does not emit fluorescence that would interfere with detecting fluorescence changes in the chemical reporters.

Solution Approach 1:

The patent applies parameter changes by modifying the material composition parameters - specifically incorporating carbon particles into the polymer resin matrix. This material parameter change achieves the desired properties of heat resistance (withstanding 400°C or higher) and non-fluorescence. The manufacturing process remains relatively simple as it involves standard molding techniques, though the material preparation requires mixing carbon particles with polymer resin, which is a straightforward compositional adjustment rather than a complex manufacturing process.
