Solution Overview

Problem

Conventional kettle lids are either bonded to the kettle body, making them difficult to clean, or have complex and costly detachable designs that complicate assembly.

Innovation Solution

A kettle lid design featuring an upper and lower lid, a button, push block assembly, push block spring, and sliding rod assemblies, allowing for easy snapping and locking mechanisms that simplify installation and use while maintaining a low cost.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the kettle lid is bonded to the kettle body, then the structure is simple, but it is inconvenient to clean inside of the kettle

Engineering Contradiction:
Improvestructure simplicityVSAvoidcleaning convenience
Core Design Contradiction:
Ease of manufactureVSEase of operation

Solution Approach 1:

The kettle lid is segmented into an upper lid and a lower lid that can be separated from each other. The upper lid can be removed from the lower lid, allowing users to clean inside the kettle body easily while maintaining a relatively simple overall structure. This segmentation resolves the contradiction by enabling disassembly for cleaning purposes.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If the kettle lid is made detachable with locking mechanism, then cleaning convenience is improved, but the structure becomes complicated and cost increases

Engineering Contradiction:
Improvecleaning convenienceVSAvoidstructure complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The kettle lid is divided into an upper lid and a lower lid that can be easily separated without complex locking mechanisms. The snap-fit connection allows simple assembly and disassembly for cleaning, avoiding the need for complicated locking structures while maintaining ease of operation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The upper lid is designed to be easily extractable from the lower lid. By simplifying the connection mechanism to a basic snap-fit structure, the design enables easy removal of the upper lid for cleaning purposes without requiring complex locking or unlocking operations.

Inventive Principle:
Principle #2Taking out (Extraction)

3Ease of operation

If the kettle lid is made detachable with locking mechanism, then cleaning convenience is improved, but the assembly becomes complicated

Engineering Contradiction:
Improvecleaning convenienceVSAvoidassembly simplicity
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

The kettle lid is segmented into upper and lower parts with a simple snap-fit connection. This segmentation allows easy separation for cleaning while keeping the assembly process simple, as the components can be easily joined and separated without complex locking mechanisms.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The upper lid is designed for easy extraction from the lower lid through a simplified connection mechanism. This design enables straightforward assembly and disassembly operations, improving both manufacturing ease and cleaning convenience without requiring complex locking structures.

Inventive Principle:
Principle #2Taking out (Extraction)
