Double-Folding Cooking Utensil With Locking Rotating Handle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cooking utensils with single-handed handles face storage and packing inefficiencies due to their elongated design, and foldable utensils with single rotating parts are inconvenient during cooking. Additionally, the high cost of developing a double rotating structure has hindered market adoption.
Innovation Solution
A cooking utensil with a double folding structure featuring a rotatable body and handle part connected via a rotating part with multiple holes, and a sliding part that prevents the body and handle from being folded during cooking while allowing the rotating part to be freely folded when not in use, reducing storage volume and improving usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single-handed handle is used to protect the user's hand from heat, then safety is improved, but the handle length increases causing storage and packing inefficiency
Solution Approach 1:
The handle is designed with a rotating part that allows it to change from an extended straight configuration during use to a folded compact configuration for storage. The rotating mechanism enables the handle to dynamically adapt its shape, providing both safety during cooking and compactness for storage.
2Reliability
If the handle is made elongated to protect the user's hand, then safety is improved, but the handle interferes with the user's arm during movement
Solution Approach 1:
The rotating part enables the handle to transition between extended and folded states, allowing the user to have a long handle for safety during cooking, but the ability to fold it back to avoid interference with the arm during movement or when not in use.
3Ease of operation
If a single rotating part is used to enable folding, then storage convenience is improved, but the coupling is released by cooking acts such as mixing or overturning
Solution Approach 1:
The rotating part is divided into multiple holes that can engage with corresponding protrusions on the handle segments. This segmentation creates multiple potential coupling points, providing both rotational freedom for folding and secure engagement during cooking operations.
Solution Approach 2:
Different regions of the rotating part serve different functions: some holes are positioned to allow rotation and folding for storage convenience, while other holes provide secure coupling during cooking acts. The local structure varies to meet different functional requirements.
4Ease of operation
If a double rotating structure is implemented to solve folding issues, then storage convenience and reliability are improved, but the manufacturing cost increases excessively
Solution Approach 1:
The rotating part combines multiple functions into a single component: it enables folding for storage, provides secure coupling during use, and allows rotational movement. By merging these functions into one integrated part rather than using separate rotating mechanisms, the manufacturing cost is reduced while maintaining reliability and convenience.

AI summary
Disclosed is a cooking utensil with double folding which includes a body part of which one of cooking utensils such as scoops, forks, spoons, flip, spatulas and cooking spoons is selectively formed from an end, a handle part, and a rotating part which includes at least two or more holes formed in one side and the other side thereof so that one end is connected to the first rack portion and the other end is connected to the second rack portion to be doubly foldable.
