Solution Overview

Problem

Conventional scissors with a garlic mincing function are inefficient and cumbersome, requiring multiple operations to mince garlic, and lack a convenient method to discharge minced garlic, while also not addressing the need for a fish scaling function in a multipurpose kitchen utensil.

Innovation Solution

Design of multipurpose scissors with a garlic mincing unit featuring a crushing part with engaging depressions and protrusions on the handles, and a discharge guiding part to collect and discharge minced garlic, along with a fish scaling unit having sawtoothed contact surfaces on the back side of the blades for easy scale removal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conventional scissors with a garlic mincing function are used, then garlic can be minced, but the operation is cumbersome and inefficient requiring multiple steps

Engineering Contradiction:

Improvegarlic mincing efficiencyVSAvoidoperational convenience

Core Design Contradiction:

ProductivityVSEase of operation

Solution Approach 1:

The patent combines the garlic mincing function and discharge function into a single integrated unit on the scissor blade. The crushing part with depressions and protrusions merges the mincing action with the discharge groove, allowing continuous operation without separate tools or multiple steps, thereby improving both productivity and ease of operation

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The discharge groove is designed to allow minced garlic to be continuously discharged during the scissor closing action. This eliminates the need to open the scissors to remove garlic, enabling continuous mincing operation and improving efficiency while maintaining simple operation

Inventive Principle:

Principle #20Continuity of useful action

2Ease of operation

If conventional scissors without discharge guidance are used, then garlic can be minced, but the minced garlic cannot be conveniently discharged

Engineering Contradiction:

Improvegarlic discharge convenienceVSAvoidmincing operation efficiency

Core Design Contradiction:

Ease of operationVSProductivity

Solution Approach 1:

The discharge groove acts as an intermediary structure between the crushing part and the external environment. It receives minced garlic from the crushing part and guides it outward, facilitating convenient discharge while maintaining continuous operation and improving overall efficiency

Inventive Principle:

Principle #24Intermediary (Mediator)

3Adaptability or versatility

If scissors with additional functions are added, then more kitchen tasks can be performed, but the device complexity increases

Engineering Contradiction:

Improvekitchen task functionalityVSAvoidscissors structure complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The scissor blade is designed with multiple functions integrated into a single structure: cutting function (original), garlic mincing function (crushing part with depressions and protrusions), and garlic discharge function (discharge groove). This multi-functionality approach increases adaptability while avoiding the complexity of separate tools

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent merges multiple kitchen functions (cutting, garlic mincing, garlic discharge) into a single scissor device. The crushing part and discharge groove are integrated on the blade, combining what would traditionally require separate tools into one unified device, thereby increasing versatility without proportionally increasing complexity

Inventive Principle:

Principle #5Merging (Combining)

AI summary

Disclosed herein are multipurpose scissors. In the multipurpose scissors, an upper blade and a lower blade are connected by a pivot pin, opposite cutting edges are formed on the upper and lower blades in front of the pivot pin, and upper and lower handles configured to grip the upper and lower blades and to perform cutting work are provided in back of the pivot pin. The multipurpose scissors include a garlic mincing unit, including: a crushing part configured such that pluralities of depressions and protrusions are formed to engage with each other on the friction surfaces of the upper and lower handles; and a discharge guiding part formed on the inner side of the crushing part, and configured such that an inclined guide surface and a discharge groove configured to discharge garlic, minced via the crushing part, in one direction are formed therein.
