Food blender and scraper assembly for a food blender
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing food processing devices with top-mounted scraper assemblies can be cumbersome to operate and require complex manual steps for coupling and decoupling the scraper motor from the blades, making them difficult to use effectively.
Innovation Solution
A food processing system with a motor-driven scraper assembly that includes a rotatable drive coupling movable between raised and lowered positions, allowing easy engagement and disengagement with the scraper blades, facilitated by a lifter handle and linkage mechanism for seamless operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a top-mounted scraper assembly is used to scrape foodstuffs from container walls during processing, then the processing effectiveness is improved, but the device complexity and ease of operation deteriorate due to cumbersome coupling and decoupling steps
Solution Approach 1:
The scraper motor is made movable relative to the processing container, transitioning between a raised position (disengaged) and a lowered position (engaged). This dynamic configuration allows the motor to be selectively positioned for engagement with or disengagement from the scraper blades, resolving the contradiction between maintaining processing effectiveness and improving ease of operation.
2Productivity
If a top-mounted scraper assembly with integrated motor is used, then the scraping function is improved, but the device complexity increases due to additional coupling mechanisms
Solution Approach 1:
The motor's movable mounting allows it to transition between raised and lowered positions, enabling selective engagement with the scraper blades. This dynamic approach provides the scraping function while avoiding permanent integration, thereby reducing overall device complexity.

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, a motor-driven scraper assembly connected to the lid and being configured to scrape interior sidewalls of the processing container, the motor-driven scraper assembly having a hub, and a motor having a rotatable drive coupling, at least the drive coupling being moveable between a raised position where the drive coupling is vertically spaced from the hub of the motor-driven scraper assembly, and a lowered position where the drive coupling is engaged with the hub.
