Ball-Joint Stirring Disc for Lump-Free Thick Mixture Cooking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional stirring tools are inadequate for handling thick cooking mixtures, as they fail to prevent lump formation, ensure even heat distribution, and prevent sticking or burning, making it difficult to achieve a smooth texture in gravies, sauces, and soups.
Innovation Solution
A stirring utensil with a concave-convex stirring disc and a ball and socket joint, allowing for rotational and tilting movement, along with apertures for mixing and removing lumps, and a heat-resistant handle for ergonomic comfort, designed to detach for easy cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional spoons are used to stir thick mixtures, then the utensil structure is simple, but the stirring effectiveness is insufficient and lumps form
Solution Approach 1:
The stirring disc is segmented with multiple apertures (holes) throughout its surface, dividing the stirring action into multiple flow paths. This segmentation allows the thick mixture to be broken up and circulated through the apertures, preventing lump formation while maintaining a relatively simple overall disc structure.
Solution Approach 2:
The stirring disc features a concave-convex three-dimensional surface profile rather than a flat traditional spoon. The concave bottom surface and convex top surface create depth and variation in the stirring action, allowing the disc to effectively reach and disrupt lumps at different depths in the thick mixture while adding dimensional complexity to an otherwise simple disc shape.
2Reliability
If vigorous stirring is applied to prevent lumps, then the mixture texture improves, but the cook becomes tired and it becomes impractical
Solution Approach 1:
The ball and socket joint introduces dynamic movement capability to the stirring disc, allowing it to tilt and rotate freely in multiple directions. This dynamic design enables the disc to adapt to the viscous resistance of thick mixtures, maintaining effective stirring contact without requiring the cook to exert excessive force, thus reducing fatigue while achieving smooth texture.
Solution Approach 2:
The apertures in the stirring disc create a porous structure that facilitates fluid flow through the disc. As the disc moves through the thick mixture, the apertures allow the mixture to pass through and be agitated from multiple directions, achieving thorough mixing and lump prevention with reduced manual effort compared to solid traditional spoons.
3Reliability
If traditional spoons are used, then the utensil is simple, but the corners and sides of the pot are not reached and burning occurs
Solution Approach 1:
The apertures are distributed across the stirring disc surface, creating multiple contact points and flow channels. This segmentation allows the mixture to be circulated and scraped from corners and sides of the pot through multiple pathways, ensuring even heat distribution and preventing burning in areas that traditional single-point spoons miss.
Solution Approach 2:
The concave-convex curved surfaces of the stirring disc enable it to conform to and scrape the curved interior surfaces of the pot more effectively than flat traditional spoons. The curved geometry allows the disc to reach corners and sides, distributing heat evenly and preventing localized burning while adding geometric complexity to the disc design.
4Ease of operation
If the handle is long to maintain hand position, then ergonomic comfort improves, but the device becomes less maneuverable
Solution Approach 1:
The ball and socket joint at the handle connection creates a dynamic pivot point that allows the stirring disc to tilt and rotate independently. This dynamic joint enables the long handle to remain stable in the user's hand while the disc end moves freely to navigate the pot interior, maintaining ergonomic comfort without sacrificing maneuverability.
Solution Approach 2:
The ball and socket joint acts as an intermediary mechanism between the handle and stirring disc. It mediates the transmission of force and motion, allowing the long handle to provide ergonomic leverage while the joint absorbs and adapts to the complex movement requirements of stirring thick mixtures, preventing the handle itself from becoming a constraint on maneuverability.

AI summary
The stirring utensil may comprise a stirring disc, a handle, and a ball and socket joint. The stirring disc may detachably couple to the handle via the ball and socket joint. The stirring utensil may be adapted for a user to stir non-solid food to mix the non-solid food and to separate lumps from the bottom of a pot. As non-limiting examples, the non-solid food may be soup, sauce, or gravy. The stirring disc may make contact with the bottom of the pot to separate the non-solid food from the pot in order to prevent the non-solid food from scorching. The stirring disc may be elevated above the bottom of the pot to mix the non-solid food at all depths. The ball and socket joint may enable the stirring disc to rotate and tilt while stirring.
