Food Processor Hinge-Latched Lid and Rotatable Blade for Safe Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Food processors face challenges with inconvenient access to the food processing chamber, insecure attachment to the base, and the need to remove the blade assembly for storage, which can be hazardous.
Innovation Solution
A food processor design featuring a removably secured jar with a hinge-latched lid, a rotatable shaft for the blade assembly, and an adaptor for easy engagement and disengagement, allowing the blade assembly to be safely stored in a non-use position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the lid is twisted onto the bowl/jar to create the food processing chamber, then the food processing chamber is sealed, but it takes additional time to untwist the lid to access the food processing chamber
Solution Approach 1:
The lid is changed from a static twisted-on design to a dynamic hinged design that can swing open and closed. The hinge mechanism allows the lid to move between a closed position (sealing the chamber) and an open position (allowing access), eliminating the need to completely remove or untwist the lid while maintaining the sealing function when closed.
2Reliability
If the bowl/jar is twisted onto the base of the food processor, then the bowl/jar is secured to the base, but it takes additional time to untwist the bowl/jar from the base in order to remove the bowl/jar from the base
Solution Approach 1:
The attachment mechanism is changed from a static twisted-on design to a dynamic bayonet-style engagement that allows quick insertion and removal. The bowl/jar can be quickly attached to and detached from the base by a simple rotational motion, eliminating the need for extensive twisting while maintaining secure attachment during operation.
3Ease of operation
If the blade assembly is left in a use position, then the blade assembly is ready for operation, but it is dangerous for safety reasons
Solution Approach 1:
The blade assembly is made rotatable to enable it to assume different positions. It can be rotated to a vertical retracted position during storage to eliminate safety hazards, and to a horizontal operational position when food processing is needed. This dynamic positioning allows the system to switch between safety and operational readiness states.
Solution Approach 2:
The blade assembly is automatically positioned in a safe vertical retracted position when the bowl/jar is removed from the base, before any potential hazard can occur. This preliminary positioning action ensures safety is maintained during storage and transport, while the blade can be quickly brought to the operational position when needed.
4Object-affected harmful factors
If the blade assembly needs to be removed from the food processor during storage, then safety is improved, but the device complexity increases and convenience decreases
Solution Approach 1:
The blade assembly is made rotatable on its shaft, allowing it to be positioned vertically in a retracted state during storage without requiring removal from the food processor. This dynamic positioning capability maintains safety while eliminating the complexity and inconvenience of blade removal and reinstallation.

AI summary
A food processor for processing food stuffs having a base assembly, a jar assembly, and a blade assembly that can be rotated from a use position to a stored position is disclosed. The food processor includes a lid that is connected to the jar assembly by a hinge and closed by use of a latch. The jar assembly is connected to the base assembly by the use of push pins on the base assembly which engage corresponding holes on the jar assembly.
