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 within the processing container, 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 that moves the motor housing vertically to connect or disconnect the drive coupling with the hub, ensuring smooth and reliable operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If a top-mounted scraper assembly is used to scrape foodstuffs from the sides of the processing container, then the scraping function is improved, but the device complexity and ease of operation deteriorate due to cumbersome coupling and decoupling steps
Solution Approach 1:
The scraper motor housing is made movable between an engaged position (where the drive coupling connects to the hub) and a disengaged position. This dynamic configuration allows the motor to be easily coupled to and decoupled from the scraper blades, resolving the contradiction between providing effective scraping and maintaining ease of operation.
2Object-generated harmful factors
If manual steps are required to couple and decouple the scraper motor, then the scraping function is achieved, but the ease of operation and productivity worsen due to complex manual assembly steps
Solution Approach 1:
The motor housing is designed to be dynamically movable between engaged and disengaged positions, eliminating the need for complex manual assembly steps. This dynamic design allows users to quickly couple and decouple the scraper motor, significantly improving operational efficiency and productivity.
3Stability of the object's composition
If the drive coupling is fixed in position, then the structural stability is improved, but the ease of operation worsens due to inability to easily engage or disengage the scraper motor
Solution Approach 1:
The drive coupling is integrated with the movable motor housing, allowing it to transition between fixed (engaged) and movable (disengaged) states. This dynamic design maintains structural stability during operation while enabling easy engagement and disengagement when needed.
Solution Approach 2:
The movable motor housing acts as an intermediary between the fixed hub and the external environment, facilitating easy coupling and decoupling of the drive coupling without compromising the structural stability of the overall scraper assembly.

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.
