Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the magnetic force line generating coil is located under the frying basket to heat the frying oil, then the heating function is achieved, but the magnetic force line is not distributed evenly into the frying container, causing different internal temperatures and non-uniform food frying
Solution Approach 1:
The heating system is segmented into multiple independent heating zones with separate control circuits. The frying container bottom is divided into multiple heating regions, each equipped with its own heating element that can be independently controlled to achieve uniform temperature distribution across the entire cooking surface.
Solution Approach 2:
Different regions of the heating system are designed with different heating characteristics to match the specific thermal requirements of various cooking zones. The heating elements are strategically positioned and configured to provide localized heating control, ensuring optimal temperature distribution for different food types and cooking methods.
2Ease of operation
If manual pouring of frying oil is used to feed the frying container, then the configuration is simple, but the frying oil may be spattered to the outside or spilled by mistake
Solution Approach 1:
The system incorporates an automatic oil feeding mechanism that self-regulates the oil supply process. The feeding pump automatically draws oil from the storage container and delivers it to the frying container through controlled piping, eliminating the need for manual pouring and preventing oil spattering and spilling through automated controlled dispensing.
Solution Approach 2:
An automated oil feeding system acts as an intermediary between the oil storage container and the frying container. This intermediate mechanism includes controlled piping and dosing equipment that safely transfers oil without direct human contact, preventing oil spattering and spilling while maintaining simple operation for the user.
3Extent of automation
If a separate oil feed pipe is installed above the frying container to automate oil supply, then oil spilling is prevented, but the fryer configuration becomes complicated
Solution Approach 1:
The oil feeding system is nested within the existing fryer structure. The feeding pump and piping are integrated into the fryer's internal framework, with the oil delivery system positioned to utilize existing spatial arrangements. This nesting approach automates oil feeding while minimizing additional external components and maintaining a compact, simple overall configuration.
Solution Approach 2:
The automated oil feeding system is designed to perform multiple functions: it not only prevents oil spilling but also controls oil dosage, monitors oil levels, and can be integrated with the heating control system. This multi-functionality reduces the need for separate dedicated components, thereby simplifying the overall fryer configuration while achieving automation.
4Device complexity
If the discharge pipe is used for both oil discharge and feeding, then the configuration is simplified, but frying remnants may be introduced into the feed pipe
Solution Approach 1:
The system performs preliminary separation of frying remnants from oil before the oil is fed back into the container. A filtering mechanism is positioned in the oil discharge path to remove food particles and debris before the cleaned oil enters the feeding pump and piping, preventing blockages while maintaining a simplified pipe system configuration.
Solution Approach 2:
A filtering system acts as an intermediary between the discharge pipe and the feed pipe. This intermediate filtering stage separates frying remnants from the oil stream, allowing the cleaned oil to proceed through the feeding system without introducing contaminants that could cause blockages, while maintaining overall system simplicity.
