Food processor having detachable spring-loaded lid
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing food processing devices lack ease of use, functionality, and ergonomics, particularly in terms of lid design which often results in drippings and requires complex locking mechanisms.
Innovation Solution
A food processor with a detachable, spring-loaded lid that is pivotally connected to the work bowl via a spring-loaded hinge, featuring a latch for securing the lid and a circumferential lip to contain drippings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed lid design is used, then the lid remains securely in place during operation, but the lid cannot be easily detached for cleaning and maintenance
Solution Approach 1:
The lid assembly is segmented into detachable components including the lid body, feed tube, and spout assembly that can be separated for cleaning while maintaining secure attachment during operation through the hinge and latch mechanisms
Solution Approach 2:
The lid transitions from a static fixed design to a dynamic system with a spring-loaded hinge allowing movement between open and closed positions, and a latch mechanism that provides secure attachment when closed but allows easy release when needed
2Reliability
If a complex locking mechanism is used, then the lid is securely locked during operation, but the device complexity increases
Solution Approach 1:
The spring-loaded hinge provides automatic return to open position and maintains pressure on the latch mechanism, while the latch itself automatically engages when the lid is closed, eliminating the need for complex manual locking procedures or additional actuators
3Device complexity
If a traditional lid design is used, then the structure is simple, but drippings occur from the lid during operation
Solution Approach 1:
The circumferential lip extends downward from the lid body to create a drip containment channel that redirects liquid back into the bowl, adding a vertical dimension to the lid structure that prevents drippings without complicating the overall design
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 solution enhances ease of use and ergonomics by allowing easy detachment and locking of the lid, while the spring-loaded design and circumferential lip effectively prevent drippings, improving overall user experience and cleanliness.
Implementation Method 1
The lid is pivotally connected to a work bowl via a spring-loaded hinge that biases the lid to an open position

AI summary
A food processor includes a base, a motor disposed within the base, an output shaft operatively connected to the motor and extending outwardly from the base, the output shaft being rotatable about a shaft axis upon actuation of the motor, a work bowl received on the base, the work bowl having a receiving channel on an upper portion thereof, and lid removably connected to the work bowl and having a coupling member received in the receiving channel. The lid is pivotable between a first position, in which the lid rests atop the work bowl and substantially encloses an interior of the work bowl, and a second position, in which the lid is pivoted out of alignment with the work bowl to provide access to the interior of the work bowl.
