Motor-Driven Dasher Assembly for Continuous Blender Jar Scraping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing food processing devices generate excessive noise and require manual scraping of ingredients from the blender jar, which is time-consuming and inefficient, especially when processing thicker products.
Innovation Solution
A food processing system with a motor-driven dasher assembly integrated into the lid that scrapes the interior sidewalls of the blender jar during operation, combined with a sound enclosure that reduces noise levels and automatically initiates processing when closed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a traditional food processing device is used, then the device structure is simple, but the noise level is excessive
Solution Approach 1:
The patent extracts the noise-generating components (motor and processing jar) from the general environment by enclosing them in a sound enclosure. The sound enclosure acts as a separate compartment that isolates the harmful noise, allowing the rest of the device to remain simple while effectively reducing noise levels.
Solution Approach 2:
The patent implements a nested structure where the processing jar is placed inside the sound enclosure, which itself is part of the base structure. This nested arrangement allows the noise-containing components to be housed within a protective shell without significantly increasing the overall device footprint or complexity.
2Productivity
If manual scraping is required for thicker products, then the device structure is simple, but the processing time increases
Solution Approach 1:
The dasher assembly performs preliminary scraping action during the blending process itself, preventing foodstuff from adhering to the jar walls in the first place. By continuously scraping during operation rather than requiring separate manual intervention, the system maintains simple device structure while significantly improving processing efficiency.
Solution Approach 2:
The motor-driven dasher enables the blending system to scrape its own container walls automatically during operation. The dasher is driven by the same motor that drives the blending blades, allowing the system to serve itself by removing adhered foodstuff without requiring external manual intervention or additional complex mechanisms.
3Ease of operation
If manual scraping is required, then the device structure is simple, but the operational complexity increases
Solution Approach 1:
The patent merges the scraping function with the blending operation by integrating the dasher assembly into the processing jar. The dasher and blending blades operate simultaneously within the same container, allowing both functions to be performed through a single integrated structure rather than requiring separate manual operations.
Solution Approach 2:
The processing jar is designed with dual functionality: it serves as both the container for blending and the surface for scraping. The dasher assembly performs multiple functions by scraping different sections of the jar walls during operation, allowing a single component to handle what would otherwise require multiple separate operations.
4Duration of action of moving object
If the lid must be removed for scraping, then the device structure is simple, but the processing continuity is interrupted
Solution Approach 1:
The motor-driven dasher operates continuously during the entire blending process, maintaining uninterrupted scraping action. The dasher rotates along with the blending blades, ensuring that foodstuff is continuously removed from the jar walls without requiring pauses or lid removal, thereby maintaining continuous useful action throughout the processing cycle.

AI summary
A food processing system includes a processing container having a motor-driven processing blade positioned at a bottom of the processing container, a lid receivable atop the processing container, and a motor-driven dasher assembly connected to the lid and being configured to scrape interior sidewalls of the processing container.
