Food Processor Lid Snap-Lock Clamp Without Twist Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing countertop food processor designs require a twist-lock mechanism for securing the lid, which can be inconvenient and may not be suitable for all sizes and configurations, necessitating a safer and more convenient locking solution.
Innovation Solution
A snap-lock mechanism is introduced, where the lid features a downwardly extending tongue with an internal hook that flexes to engage with a radially extending lip on the bowl, combined with a spring-loaded latch assembly for secure attachment without rotational movement, allowing for easy installation and removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a twist-lock mechanism is used to secure the lid to the bowl, then the lid can be locked securely, but the operation becomes inconvenient and less adaptable to various sizes and configurations
Solution Approach 1:
Instead of rotating the lid relative to the bowl as in conventional twist-lock mechanisms, this invention inverts the approach by keeping the lid and bowl stationary relative to each other during locking. The spring-loaded latch assembly automatically engages with the lid-retention lip through vertical movement only, eliminating the need for rotational operation while maintaining secure locking.
Solution Approach 2:
The spring-loaded latch assembly automatically engages with the lid-retention lip when the lid is placed on the bowl, providing self-locking functionality. The user simply needs to press the release button to unlock, and the spring mechanism handles the locking action automatically, improving ease of operation while maintaining reliability.
2Reliability
If a twist-lock mechanism is used, then the lid can be locked, but the design is not suitable for all sizes and configurations of food processors
Solution Approach 1:
The lid-retention lip and spring-loaded latch assembly create a universal locking mechanism that can be adapted to various bowl sizes and configurations. The vertical engagement approach rather than rotational engagement allows the same basic mechanism to work across different food processor models, enhancing versatility while maintaining reliable locking.
3Ease of operation
If a spring-loaded latch assembly is used instead of twist-lock, then ease of operation is improved, but the mechanism complexity increases
Solution Approach 1:
The invention merges the lid-retention lip integrated into the bowl with the spring-loaded latch assembly to create a unified locking system. By combining these elements into a single coordinated mechanism rather than separate components, the design improves ease of operation while minimizing the increase in overall system complexity.

Function Achieved in This Case
This solution provides a secure, convenient, and safe locking system that eliminates the need for twist-locking, enhancing user experience and compatibility with various food processor sizes and configurations.
Implementation Method 1
a spring-loaded latch assembly 9, of a conventional type, releasably attaches to the bowl 1
Implementation Method 2
The tongue 7, which is integrally formed with the lid 6, flexes so that as the lid 6 is installed onto the bowl, the hook 8 contacts and slides over the lid-retention lip 5

AI summary
A food processor bowl 1 has a floor 2, a sidewall 3 and a top opening 4. The exterior of the bowl 1 has a lid-retention lip 5 extending radially from the sidewall 3 and downwardly at its distal end to form, in side profile, a hook-like mechanism. The food processor lid 6 has a downwardly extending tongue 7 with an internal hook 8. The tongue 7, which is integrally formed with the lid 6, flexes so that as the lid 6 is installed onto the bowl, the hook 8 contacts and slides over the lid-retention lip 5. This flexes the tongue 7 radially outwardly until the hook 8 is slid past the lip 5, at which time the tongue moves the hook 8 underneath the lip 5. At the same time, a spring-loaded latch assembly 9 releasably attaches to the bowl 1.
