VSEngineering Contradiction Analysis

1Measurement precision

If temperature detection parts are installed inside the reactor to measure internal temperature, then measurement precision is improved, but flow resistance increases

Engineering Contradiction:
Improvetemperature measurement precisionVSAvoidflow resistance
Core Design Contradiction:
Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a fluid guide hole as an intermediary structure that channels reaction fluid to the temperature detection part. The detection part is installed in an installation hole that communicates with the reaction flow channel through this fluid guide hole, allowing the detection part to contact the fluid without protruding into the flow channel and blocking flow

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The temperature detection part is positioned in a different spatial dimension - installed in an installation hole that extends from the external surface through the heat exchanging body, rather than protruding into the flow channel. The fluid guide hole creates a separate access path that allows the detection part to be located at the opening portion without occupying flow channel space

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Power

If multiple flow channels are provided to increase heat transfer area, then heat exchange efficiency is improved, but device complexity increases

Engineering Contradiction:
Improveheat exchange efficiencyVSAvoidapparatus structure complexity
Core Design Contradiction:
PowerVSDevice complexity

Solution Approach 1:

The heat exchanging body structure serves multiple functions simultaneously: it provides the reaction flow channel and heat medium flow channel for heat exchange, contains the installation hole for temperature detection, and includes the fluid guide hole to direct fluid flow. This multi-functionality reduces the need for separate components and simplifies the overall apparatus structure

Inventive Principle:
Principle #6Universality (Multi-functionality)
