Solution Overview

Problem

Existing blind cleaner devices are cumbersome, inefficient, and prone to fluid leakage due to complex designs and lack of sealing arrangements, making them difficult to use for cleaning large numbers of window blinds.

Innovation Solution

A blind cleaner device with a simplified design featuring a body with integrated sealing plugs on a cover, which waterproof the openings and prevent fluid leakage, reducing the number of parts and enhancing usability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional modular design with multiple openings is used, then cleaning function is provided, but fluid leakage occurs and device complexity increases

Engineering Contradiction:

Improvefluid sealingVSAvoidnumber of parts

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The sealing plug is merged with the cover to form an integrated component. The cover is designed with a plug receiving cavity that receives the sealing plug, and the protrusion on the cover engages with the recess in the sealing plug, creating a unified structure that eliminates separate sealing components while maintaining effective sealing function.

Inventive Principle:

Principle #5Merging (Combining)

2Reliability

If multiple separate sealing plugs are used, then openings are sealed, but risk of loss or misplacement increases

Engineering Contradiction:

Improvesealing functionVSAvoidhandling convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

Multiple sealing plugs are merged into a single integrated cover assembly. The cover includes multiple plug receiving cavities, each containing a sealing plug, all held together as one unit. This integration ensures that sealing plugs cannot be lost or misplaced during cleaning operations, as they remain permanently attached to the cover structure.

Inventive Principle:

Principle #5Merging (Combining)

3Reliability

If complex assembly structure is used, then sealing is achieved, but assembly and disassembly difficulty increases

Engineering Contradiction:

Improvefluid proofingVSAvoidassembly ease

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The cover is segmented into functional zones: the cover body, plug receiving cavities, protrusions, and recesses. Each component has a specific function and fits together through simple geometric interlocking features. This segmentation allows for easy manufacturing and assembly while maintaining effective sealing, as each part can be produced independently and assembled through straightforward engagement of the protrusion-recess interfaces.

Inventive Principle:

Principle #1Segmentation
