Adjustable lid for bakeware pan
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Kitchen storage is cluttered with multiple lids of different sizes, each designed for specific bakeware pans, making it cumbersome to find a matching lid for variously sized pans.
Innovation Solution
An adjustable lid system featuring a removable, reversible adaptor that fits multiple bakeware pans of different sizes by adjusting its position and incorporating flexible fingers for additional support, ensuring a secure fit without the need for multiple lids.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate lid is designed for each specific bakeware pan size, then each lid provides a precise fit for its corresponding pan, but the number of lids required increases, leading to cluttered storage and reduced convenience
Solution Approach 1:
The patent applies universality by designing a single lid that can fit multiple bakeware pan sizes through interchangeable adaptors. The lid body remains universal while adaptors are swapped to match different pan dimensions, eliminating the need for multiple dedicated lids and reducing storage clutter while maintaining precise fits.
Solution Approach 2:
The patent applies segmentation by dividing the lid system into separate components: a universal lid body and multiple size-specific adaptors. This segmentation allows the lid to be customized for different pan sizes by attaching the appropriate adaptor, resolving the contradiction between having a precise fit and avoiding multiple lids.
2Device complexity
If a universal lid without adaptors is used, then the structure remains simple, but the lid cannot securely fit pans with different external dimensions
Solution Approach 1:
The patent applies the intermediary principle by introducing adaptors as mediating components between the universal lid and various pan sizes. These adaptors act as intermediaries that translate the universal lid's dimensions to match specific pan external dimensions, enabling secure fits without complicating the lid's core structure.

AI summary
A lid and adaptor assembly capable of being used with at least two food containers such as baking pans having different external dimensions. A pair of clasps are rotatably disposed on opposite side of the lid, each clasp capable of being rotated from an open position to a closed position. A pair of adaptors are provided for connection to the clasps in a first orientation and a second orientation, and each adaptor has a first surface capable of engaging a first food container when the adaptor is in the first orientation, and a second surface capable of engaging a second food container when the adaptor is in the second orientation. A pair of flexible fingers may also be used on the clasp to act as the adaptors to enable use with food containers having different external dimensions.
