Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If conventional heating and gas supply methods are used in treatment systems, then the system can operate and heat workpieces, but energy consumption is high due to inefficient gas heating and recirculation
Solution Approach 1:
The heating gas is circulated continuously through the treatment room sections via the heating gas duct, maintaining constant heat supply to the workpieces. The system ensures uninterrupted heating by recirculating the same heating gas multiple times, eliminating the need for continuous fresh gas supply and maintaining stable temperature conditions throughout the treatment process.
Solution Approach 2:
Instead of discarding used gas after a single pass through the treatment room, the system recirculates the heating gas back through the treatment room sections via the heating gas duct. This recovery and reuse of the same gas multiple times significantly reduces energy consumption and eliminates the need for continuous fresh gas supply, directly addressing the energy efficiency problem.
2Loss of energy
If a self-contained heating gas duct with recirculation is implemented, then energy efficiency improves, but the device structure becomes more complex
Solution Approach 1:
The heating gas duct serves multiple functions simultaneously: it supplies heating gas to treatment room sections, recirculates used gas back through the treatment rooms, and maintains continuous heat supply. This multi-functionality reduces the need for separate systems for gas supply, heating, and recirculation, thereby limiting the increase in structural complexity while achieving high energy efficiency.
Solution Approach 2:
The system merges the gas supply function, heating function, and recirculation function into a single integrated heating gas duct system. By combining these functions that would traditionally require separate systems, the patent achieves energy efficiency improvements while minimizing the increase in overall system complexity.
3Temperature
If heating gas is recirculated through treatment room sections multiple times, then temperature control improves, but the system requires more sophisticated gas flow management
Solution Approach 1:
The system uses temperature sensors in the treatment room sections to monitor the actual temperature conditions. This feedback information is used to automatically adjust the heating gas flow rate and recirculation parameters, ensuring that the desired temperature is maintained throughout the treatment process despite variations in workpiece loading or environmental conditions.
Solution Approach 2:
The heating gas duct system automatically regulates its own operation by using temperature feedback to control gas flow. The system self-adjusts the recirculation rate and heating intensity based on actual temperature measurements, eliminating the need for complex manual control while maintaining precise temperature management.

AI summary
In order to provide a treatment system that is simple in design and enables energy-efficient workpiece treatment, it is proposed that the treatment system comprise the following: a treatment room comprising several treatment room sections, each assigned to one of several separate recirculating air modules of the treatment system; a heating system comprising a self-contained hot gas flow, with several recirculating air modules coupled to the hot gas flow, in particular for heating the gas passed through the treatment room sections.
