A lid for a food processor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing blender lids are difficult to remove, do not adequately seal under negative pressure, and are not easily adaptable for use with multiple appliances, leading to inefficiencies in food processing and storage.
Innovation Solution
A lid design featuring latch members with flexible projections and a pivotally connected cover that includes sealing projections to securely engage the rim and spout openings, allowing for easy operation and vacuum sealing, enabling seamless integration with both blender and juicer functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the lid is designed to withstand forces from circulating contents to securely seal the vessel, then sealing reliability is improved, but ease of operation deteriorates (difficult to remove)
Solution Approach 1:
The lid is divided into a main body and a separate cover portion that can be independently removed. The cover can be detached from the main lid body, allowing users to easily access or remove parts of the lid without having to overcome the full sealing force of the entire lid assembly.
Solution Approach 2:
The latch members are designed to be movable between engaged and disengaged states. The latches can be easily activated by pressing or sliding motions, dynamically changing from a locked sealing state to an unlocked removable state, facilitating easy opening while maintaining secure sealing during operation.
2Adaptability or versatility
If existing lids are used for storage purposes with other appliances, then adaptability is improved, but sealing effectiveness deteriorates (insufficient vacuum sealing)
Solution Approach 1:
The lid is designed with universal compatibility features that allow it to be used with different appliances for both processing and storage functions. The standardized interface and sealing mechanisms enable the same lid to effectively seal during blending operations and provide adequate vacuum sealing for storage purposes.
