Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If coal and/or gas are used for roasting chestnuts, then roasting can be achieved, but vapor and smoke emissions occur causing hygiene and safety problems in public spaces
Solution Approach 1:
The patent changes the energy source parameter from combustion-based (coal/gas) to electric heating, eliminating vapor and smoke emissions while maintaining the roasting function. The heating element uses electrical resistance to generate heat directly, transforming the physical-chemical process from combustion to resistive heating.
Solution Approach 2:
The patent replaces the mechanical/chemical combustion system with an electrical heating system. The combustion process involving fuel oxidation is substituted by electrical resistance heating, eliminating the harmful emissions associated with combustion while achieving the same thermal processing effect.
2Object-affected harmful factors
If electric heating is used to eliminate emissions, then hygiene and safety are improved, but automatic control and programming complexity increases
Solution Approach 1:
The patent implements automatic control systems that enable the roasting machine to operate autonomously. The control electronics automatically regulate heating temperature, timing, and vapor condensation processes without requiring manual intervention, making the increased complexity worthwhile by eliminating emissions and ensuring consistent roasting quality.
Solution Approach 2:
The patent incorporates control and programming electronics that likely include feedback mechanisms to monitor and adjust heating parameters, vapor condensation rates, and overall roasting conditions. This automated feedback control system manages the complexity by optimizing performance and maintaining safety standards automatically.
3Object-affected harmful factors
If vapor condensation and recovery systems are added, then hygiene is improved by eliminating emissions, but device complexity increases
Solution Approach 1:
The patent converts the harmful vapor emissions into a beneficial resource by implementing a condensation and recovery system. The vapor produced during roasting is captured, condensed back to liquid form, and the liquid is collected and potentially reused or disposed of properly, transforming an environmental hazard into a controlled process output.
Solution Approach 2:
The patent implements a vapor recovery system that captures condensible vapors during the roasting process, condenses them through cooling, and collects the resulting liquid in a reservoir. This prevents vapor emissions into the environment and allows for proper disposal or potential reuse of the condensed material.
