Solution Overview

Problem

Existing household cutting appliances, such as mandolins, are difficult to clean due to the accumulation of food juices and particles on the walls of the working chamber.

Innovation Solution

Incorporating a removable intermediate receptacle within the working chamber that allows the cutting tool to move in translation, along with a lockable cover and control mechanism to prevent accidental operation, and a peripheral skirt to channel juices away from the chamber walls, enhancing cleaning efficiency and safety.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If a fixed working chamber is used to house the cutting tool, then the structural stability is improved, but the ease of cleaning deteriorates due to accumulation of food juices and particles on the walls

Engineering Contradiction:
Improvestructural stabilityVSAvoidease of cleaning
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The working chamber is segmented into a fixed outer chamber and a removable inner receptacle. The inner receptacle can be detached and cleaned separately, while the fixed outer chamber remains stable. This segmentation allows the cleaning function to be performed on the removable part without compromising the structural stability of the overall device.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The removable inner receptacle is extracted as a separate component from the fixed working chamber. By taking out this inner receptacle, the cleaning process can focus on this removable element, preventing food residues from soiling the fixed chamber walls, thus maintaining structural stability while improving ease of cleaning.

Inventive Principle:
Principle #2Taking out (Extraction)

2Ease of operation

If the working chamber is open downwards at the cutting area to allow food passage, then the ease of operation is improved, but the safety deteriorates due to risk of accidental contact with the mobile cutting tool

Engineering Contradiction:
Improveease of food passageVSAvoidsafety risk
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The opening at the bottom of the working chamber is segmented into two levels: an upper window for food passage and a lower opening with restricted access. This segmentation allows food to pass through the upper window while the lower opening's restricted access prevents accidental contact with the cutting tool, thus maintaining ease of operation while improving safety.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The peripheral skirt acts as an intermediary element between the cutting zone and the external environment. It channels food residues and juices away from the chamber walls while the restricted lower opening serves as a mediator that allows food passage but blocks direct access to the cutting tool, thereby maintaining operational ease while enhancing safety.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If a peripheral skirt is added to channel juices away from the chamber walls, then the ease of cleaning is improved, but the device complexity increases

Engineering Contradiction:
Improveease of cleaningVSAvoidstructural complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The peripheral skirt is merged with the removable inner receptacle, forming an integrated component. This merging allows the peripheral skirt to perform its function of channeling juices away from the chamber walls without being a separate complex structure, thus improving ease of cleaning while minimizing the increase in device complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The peripheral skirt serves multiple functions: it channels juices away from the chamber walls, defines the opening for food passage, and contributes to the structural integrity of the removable inner receptacle. This multi-functionality reduces the need for additional separate components, thereby improving ease of cleaning without significantly increasing device complexity.

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

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
