Solution Overview

Problem

Existing deep-frying units face inefficiencies due to long process paths and separate oil quality management, leading to overcooking and increased waiting times for users, especially when handling multiple orders.

Innovation Solution

A deep-frying unit with an open-top oil pan capable of holding multiple baskets simultaneously, where each basket can be independently moved using a transport unit, allowing for simultaneous frying and optimized oil temperature and quality management, along with adjustable immersion depths and a system for oil filtration and recycling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If separate oil pans are used for each basket, then each basket can be fried independently, but the device complexity and manufacturing costs increase significantly

Engineering Contradiction:
Improveindependent frying capabilityVSAvoidstructure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The oil pan is divided into multiple independent frying zones separated by partition walls, allowing each zone to function independently while sharing the common oil pan structure. This enables separate temperature control and frying processes for different baskets without requiring completely separate oil pans, thus reducing device complexity while maintaining adaptability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The common oil pan serves multiple functions: it provides a shared heating source for all zones, maintains overall oil temperature stability through large oil volume, and allows simultaneous frying of multiple different food items in separate zones. This multi-functionality reduces the need for multiple separate systems.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Productivity

If multiple baskets are fried simultaneously in separate oil pans, then frying capacity increases, but the waiting time for users increases due to long transport paths

Engineering Contradiction:
Improvefrying capacityVSAvoidwaiting time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

Multiple frying zones are merged into a single common oil pan with a shared heating system and centralized transport mechanism. This allows baskets to be moved directly between loading and unloading positions through the oil pan without long external transport paths, significantly reducing waiting time while maintaining high frying capacity.

Inventive Principle:
Principle #5Merging (Combining)

3Temperature

If a single large oil pan is used for multiple baskets, then oil temperature consistency improves, but the ability to control frying conditions for each basket independently decreases

Engineering Contradiction:
Improveoil temperature consistencyVSAvoidindependent condition control
Core Design Contradiction:
TemperatureVSAdaptability or versatility

Solution Approach 1:

The single large oil pan is segmented into multiple zones by partition walls, creating separate frying environments. Each zone can have independent temperature control while benefiting from the thermal mass of the entire oil pan, thus achieving both temperature consistency and independent condition control.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different zones within the oil pan can have different temperature settings, heating powers, or frying conditions tailored to specific food items being fried in each zone, while the overall system maintains stable oil temperature through the large oil volume.

Inventive Principle:
Principle #3Local quality

4Ease of operation

If separate transport units are used for each basket, then independent basket movement is achieved, but the device complexity and maintenance requirements increase

Engineering Contradiction:
Improveindependent basket movementVSAvoidtransport system complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

Multiple basket transport functions are merged into a single centralized transport unit that can move multiple baskets simultaneously or sequentially. This shared transport system reduces the number of independent mechanisms required, simplifying the overall device structure and reducing maintenance needs while still enabling independent basket movement.

Inventive Principle:
Principle #5Merging (Combining)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

This solution enables efficient, simultaneous frying of multiple items with uniform oil quality, reducing waiting times and preventing overcooking by allowing for independent control of each basket's frying conditions and maintaining oil quality through continuous filtration and recycling.

Implementation Method 1

A heating coil is provided inside the oil pan, spaced apart from the base and side walls, for heating the oil contained within the pan

Methodology Applied
Scientific EffectJoule heating: Joule Heating

Implementation Method 2

Due to the distance between the heating coil and the base, a zone of cooler oil can form below the coil

Methodology Applied
Scientific EffectConvection: Convection
