Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current keyboard structures are inconvenient to clean due to the need for disassembly of top and bottom covers, which results in scattered components and difficulty in accessing dust and dirt accumulation between key caps.

Innovation Solution

A keyboard structure with a dirt-proof structure between the circuit board and the covers, allowing for easy disassembly of the first cover while keeping the circuit board, dirt-proof structure, and second cover as an intact assembly, featuring a partition or thin film and drain holes for effective dust and water prevention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If the top cover and bottom cover are fixed together with multiple components, then the structural integrity is improved, but the ease of cleaning deteriorates because tools are required for disassembly

Engineering Contradiction:

Improvestructural integrityVSAvoidease of cleaning

Core Design Contradiction:

Stability of the object's compositionVSEase of operation

Solution Approach 1:

The keyboard structure is segmented into three main parts: top cover, bottom cover, and an intermediate assembly (circuit board + dirt-proof structure) that remains connected. This allows the top cover to be removed independently for cleaning while the rest remains intact.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The dirt-proof structure is extracted as a separate component that is integrated with the circuit board and bottom cover, allowing it to be removed as a unit from the top cover assembly, facilitating easier cleaning access.

Inventive Principle:

Principle #2Taking out (Extraction)

2Ease of operation

If the top cover and bottom cover are disassembled for cleaning, then access to dust and dirt is improved, but the device complexity increases due to scattered components

Engineering Contradiction:

Improveaccess to dust and dirtVSAvoiddevice complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The circuit board and dirt-proof structure are merged into a single integrated assembly that remains connected during disassembly. This reduces the number of scattered components when the top cover is removed, simplifying the cleaning process.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The dirt-proof structure is pre-installed between the circuit board and top cover, creating a ready-to-remove intermediate assembly that maintains structural connections before cleaning is needed.

Inventive Principle:

Principle #10Preliminary action

3Ease of operation

If the dirt-proof structure is integrated with the circuit board and second cover, then the ease of cleaning is improved, but the manufacturing precision requirements increase

Engineering Contradiction:

Improveease of cleaningVSAvoidmanufacturing precision

Core Design Contradiction:

Ease of operationVSManufacturing precision

Solution Approach 1:

The dirt-proof structure uses a thin film or partition that can be easily manufactured and integrated with the circuit board and bottom cover, reducing the precision requirements compared to rigid structural connections.

Inventive Principle:

Principle #30Flexible shells and thin films
