Adjustable Locking Lid for Controlled Steam and Liquid Draining
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cookware lacks the ability to adjust vapor escape and liquid drainage, requiring multiple utensils and posing safety risks when strainers are unavailable, with prior art devices having fixed drainage capabilities and potential for uncontrolled steam release.
Innovation Solution
A single utensil combining a cooking vessel with a strainer, featuring a lid with adjustable draining and solid regions that can lock into various positions to control vapor escape and liquid drainage, allowing for safe and convenient use without additional utensils.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed locking position is used in prior art devices, then the structure is simple, but the drainage capability is limited and cannot be adjusted
Solution Approach 1:
The locking mechanism is designed to be dynamic rather than fixed, allowing the lid to lock at multiple positions around the vessel rim. The spring-loaded latch can engage with protrusions at different angular positions, enabling adjustable drainage openings while maintaining a relatively simple overall structure.
Solution Approach 2:
The locking mechanism is segmented into discrete engagement positions with multiple protrusions around the vessel rim. Each protrusion represents a discrete locking position that can be selected, allowing the user to segment the drainage control into manageable discrete steps rather than requiring continuous adjustment.
2Ease of operation
If the lid is used as a barrier for straining, then no additional utensils are needed, but there is a risk of being burned from uncontrollable escape of hot liquid and steam
Solution Approach 1:
The locking mechanism provides automatic engagement and disengagement based on the lid position. When the lid is rotated to align drainage openings with the vessel rim, the spring-loaded latch automatically engages to lock the position, preventing accidental opening and uncontrolled escape of hot liquid and steam during the straining process.
Solution Approach 2:
The spring-loaded latch acts as an intermediary safety mechanism between the lid and vessel rim. It mediates the connection by providing secure locking when properly positioned, preventing direct contact between hot contents and the user while allowing controlled drainage through the designated openings.
3Adaptability or versatility
If multiple separate utensils are used for cooking, steam release, and straining, then each function can be optimized, but more space is required for storage and dishwasher
Solution Approach 1:
The vessel with the adjustable lid integrates multiple functions into a single device. The lid can be positioned to provide sealing for cooking, controlled drainage for straining, and adjustable vapor escape for steam release. This multi-functional design eliminates the need for separate utensils for each operation, reducing storage space requirements.
4Adaptability or versatility
If the drainage position is fixed, then the locking mechanism is simple, but the amount of drainage is limited to the size of the draining region
Solution Approach 1:
The locking mechanism transitions from a fixed single-position design to a dynamic multi-position system. The spring-loaded latch can engage with multiple protrusions positioned at different angles around the vessel rim, allowing the user to dynamically adjust the drainage opening size and position while maintaining mechanical simplicity through the reuse of the same locking components.

AI summary
An apparatus which serves as a single utensil allowing to gradually adjust vapor escape, liquid drainage speed, and particle drainage and filtering. A few of the apparatus applications are cooking utensils, pitchers, drinking cups, gardening watering and fertilizing cans, etc. The apparatus comprises a vessel having pouring regions and a lid having draining and solid regions. In use, the solid regions of the lid must be aligned with the vessel pouring regions, which is the non-straining or opened position with no vapor release. If the lid is rotated in either direction, it slides into a locking engagement with the vessel until the desired draining regions of the lid are aligned with the vessel pouring regions. This is the straining or locked position where a desirable degree of steam or liquid and particles can be released.
