Solution Overview

Problem

Conventional pots face issues with air leakage due to gaps between the container and lid, leading to food spoilage and increased manufacturing complexity, and require separate automatic air hole opening and closing mechanisms to manage steam pressure, which complicate the structure and increase costs.

Innovation Solution

A handle-interlocking airtight boiling pot design where the lid sealing mechanism is integrated with the container handle, allowing the handle to rotate between opening and closing positions to airtightly fix or release the lid and control the air hole, simplifying the configuration and reducing manufacturing steps.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If lid sealing means is provided separately from container handle, then airtight sealing is achieved, but structure becomes complicated and manufacturing costs increase

Engineering Contradiction:
Improveairtight sealingVSAvoidstructure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The lid sealing means is merged with the container handle by forming the sealing protrusion as an integral part of the handle structure. The lower end of the handle extends to form a sealing protrusion that directly contacts the lid, eliminating the need for separate sealing components while maintaining airtight functionality.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The container handle is designed to perform multiple functions: it serves as both the gripping handle and the sealing mechanism. The handle's lower end forms a sealing protrusion that engages with the lid, making the handle a multi-functional component that combines holding and sealing operations.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If automatic air hole opening and closing means is provided, then steam pressure control is improved, but lid structure becomes complicated and manufacturing costs increase

Engineering Contradiction:
Improvesteam pressure controlVSAvoidlid structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The air hole control function is merged with the handle sealing mechanism. The sealing protrusion of the handle not only seals the gap between lid and container but also covers and controls the air hole in the lid. This integration eliminates the need for separate automatic air hole opening and closing mechanisms.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The sealing protrusion of the handle performs dual functions: it seals the gap between the lid and container while simultaneously controlling the air hole. When the handle is in the closed position, the protrusion covers the air hole; when opened, the air hole is exposed, allowing steam pressure regulation without additional components.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Power

If air hole is formed in lid, then steam pressure release is achieved, but outside air enters pot causing food spoilage

Engineering Contradiction:
Improvesteam pressure releaseVSAvoidfood spoilage
Core Design Contradiction:
PowerVSObject-affected harmful factors

Solution Approach 1:

The air hole is designed to be dynamically controllable by the handle position. The sealing protrusion can cover or expose the air hole based on whether the pot is being cooked or stored. During cooking, the air hole remains covered to prevent air entry; during storage, the handle position can be adjusted to close the air hole completely, preventing both spoilage and smell leakage.

AI summary

A handle-interlocking airtight boiling pot includes: a rotational body which is rotatably supported at the side of the container and is mounted to rotate between a lid opening position and a lid closing position; a hand grip part formed at an upper end of the rotational body; and an airtightly fixing part which is formed integrally with a lower part of the hand grip part and protrudes toward the lid to airtightly fix the lid to the container by pressing an upper side of the lid when the rotational body is located at the lid closing position. The lid includes: a retaining protrusion formed at an upper side of an edge portion of the lid to catch and retain the airtightly fixing part of the rotational body at the lid closing position; and a contact groove part with which a contact surface of the airtightly fixing part gets in contact.
