Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If a conventional heating system is used without a self-contained heating gas duct, then the system design is simpler, but energy efficiency is reduced due to heat loss and inability to maintain constant temperatures
Solution Approach 1:
The heating system is segmented into a self-contained heating gas duct that is separate from the circulating air modules. This allows the heating gas to be circulated independently in a closed loop, maintaining heat within the heating system rather than mixing with the air circulation, thereby improving energy efficiency while keeping the overall system modular and manageable
Solution Approach 2:
The heating gas duct acts as an intermediary system that provides thermal energy to the circulating air modules without being directly integrated into the air circulation path. This separation allows for efficient heat transfer to the treatment room sections while maintaining independent control over heating and air circulation, resolving the contradiction between energy efficiency and system complexity
2Temperature
If heating gas is not recirculated through a closed duct, then the system design is simpler, but temperature constancy and energy efficiency deteriorate
Solution Approach 1:
The heating gas is continuously recirculated through a closed duct system, ensuring that thermal energy is continuously available in the treatment room sections. This continuous circulation maintains constant temperatures without requiring repeated heating cycles, improving temperature stability while the closed-loop design ensures energy is not lost but continuously reused
Solution Approach 2:
The closed heating gas duct system provides a feedback mechanism where the same heating gas is repeatedly circulated through the treatment room sections and back to the heating source. This continuous feedback loop allows for maintaining consistent temperatures by constantly replenishing thermal energy in the treatment zones, resolving the contradiction between temperature constancy and system complexity
3Loss of energy
If fresh gas supply is not provided separately, then the system is simpler, but gas release and energy loss increase
Solution Approach 1:
The fresh gas supply is extracted as a separate, independent system from the heating and air circulation systems. This separate fresh gas feed ensures that fresh gas can be supplied to maintain proper gas composition and pressure without interfering with the closed-loop heating gas circulation, preventing energy loss from gas release while maintaining system modularity
Solution Approach 2:
The separate fresh gas supply system serves multiple functions: it maintains proper gas composition in the treatment room, prevents energy loss by compensating for any gas release, and works in conjunction with both the heating gas duct and circulating air modules. This multi-functional approach addresses energy conservation needs without requiring complex integration with other system components
