Blender Jar Scraper Lid for Thick Mixture Wall Buildup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional blending devices face challenges in efficiently blending thicker products like nut butters or hummus, as these products tend to stick to the jar walls, requiring manual scraping and multiple interruptions of the blending process, increasing time and effort.
Innovation Solution
A blending apparatus featuring a scraper lid with elongated, contoured scrapers that extend into the jar, allowing for continuous blending by disrupting the rotational flow of food particles and scraping them off the jar walls, reducing the need for manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional blending containers are used for thicker products, then the blending process can be simple in structure, but the product will stick to the walls of the blending jar requiring manual scraping and multiple interruptions
Solution Approach 1:
The patent combines the lid and the scraper into a single integrated assembly, where the scraper is mounted on the lid and rotates together with it. This merging of components allows the scraping function to be automatically performed during the blending process without requiring separate manual intervention, thus resolving the contradiction between ease of operation and blending time
Solution Approach 2:
The scraper is pre-positioned on the lid assembly before blending begins. As the lid rotates, the scraper proactively prevents product buildup on the jar walls by continuously scraping the surface, rather than waiting for manual intervention after the problem occurs. This preliminary action eliminates the need for process interruptions
2Device complexity
If traditional blending containers are used for thicker products, then the device structure can be simple, but the user must stop the blending machine, remove the lid, manually scrape the internal walls, and repeat steps
Solution Approach 1:
The patent merges the lid and scraper into a single rotating assembly, adding minimal structural complexity while enabling continuous automated scraping. This integrated design maintains simplicity compared to having separate scraping mechanisms, yet dramatically improves productivity by eliminating manual intervention steps
Solution Approach 2:
The scraper assembly serves itself by being attached to the lid, which rotates during normal operation. The rotational motion of the lid automatically drives the scraper along the jar walls without requiring separate motors or complex mechanisms, achieving self-service functionality with minimal added complexity
3Productivity
If a scraper is added to the lid to continuously scrape the jar walls, then blending efficiency improves, but the device structure becomes more complex
Solution Approach 1:
The lid serves multiple functions: it seals the jar, provides a mounting structure for the scraper, and acts as the driving mechanism for the scraper through its rotation. This multi-functionality allows the scraper system to operate without adding separate drive mechanisms or complex structures, maintaining simplicity while improving productivity
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
The scraper lid design reduces the time and effort required to achieve a desired blend by continuously reintroducing food particles into the blending path, enhancing the efficiency and consistency of blending thicker products.
Implementation Method 1
The at least one scraper is arranged and configured to disrupt rotational flow of food particles within the internal volume

AI summary
A blending apparatus includes a blending jar and a lid. The blending jar has an internal surface defining an internal volume, and a mixing blade positioned within the internal volume. The lid is releasably mounted to the blending jar and includes at least one scraper extending into the internal volume. The at least one scraper is adjacent to the internal surface of the blending jar and is arranged and configured to disrupt rotational flow of food particles within the internal volume and/or scrape food particles from an inner surface of the blending jar.
