Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If exhaust gases are used for heating the load implement body, then the heating function is effective, but this method cannot be applied to electric machine-propelled working machines
Solution Approach 1:
The invention extracts the heating function from the exhaust gas system and separates it from the propulsion system. By using an independent heating device that draws ambient air and heats it separately, the heating function can be applied to both ICE and electric machine propelled working machines, resolving the adaptability issue while maintaining effective heating capability.
2Reliability
If heating is applied continuously to prevent material sticking, then material flow is maintained, but energy is wasted when heating is not needed
Solution Approach 1:
The invention implements dynamic control of the heating system by continuously monitoring the temperature of the load implement body and adjusting the heating output accordingly. The heating device operates only when the temperature falls below a predetermined threshold, maintaining reliable material flow while minimizing energy consumption through adaptive, condition-based operation.
Solution Approach 2:
The invention incorporates a feedback control mechanism where temperature sensors monitor the load implement body temperature and feed this information back to the heating device controller. This feedback loop enables the system to automatically adjust heating operation based on actual temperature conditions, ensuring material flow reliability while avoiding unnecessary energy consumption.
3Use of energy by moving object
If pressurized air is used for heating, then heating efficiency is improved, but the system complexity increases
Solution Approach 1:
The invention makes the air blowing device serve multiple functions: it provides pressurized air for heating, supplies air for material conveyance through the channels, and helps distribute heated air uniformly across the load implement body. By combining these functions into a single device, the system achieves improved heating efficiency without proportionally increasing system complexity.
