Solution Overview

Problem

Existing high-pressure cleaners require a large amount of space and numerous components, making them cumbersome for transportation and use.

Innovation Solution

A compact high-pressure cleaning unit with a motor and pump unit integrated into a motor housing, supported by rotatable support wheels, allowing for efficient space utilization and easy movement, with a design that includes a separate motor housing for protection and a support unit for stability, and a delivery system capable of providing 140 to 200 bar pressure and 8 to 15 l/min fluid flow.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the cleaning unit is equipped with wheels for moving or transporting, then the ease of operation is improved, but the device complexity and installation space increase

Engineering Contradiction:
Improveease of transportVSAvoidnumber of components
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The support wheel is integrated directly onto the motor housing, combining the support function with the motor assembly. This eliminates the need for separate support frames or additional mounting structures, reducing component count while maintaining mobility functionality

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The motor housing serves multiple functions: it encloses the motor, provides structural support, and acts as a mounting base for the support wheel. This multi-functionality reduces the need for separate components and minimizes installation space

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

If the motor housing is designed as a separate component from the support unit, then the ease of repair is improved, but the device complexity increases

Engineering Contradiction:
ImprovemaintainabilityVSAvoidstructural complexity
Core Design Contradiction:
Ease of repairVSDevice complexity

Solution Approach 1:

The motor housing is designed as a separable component from the support unit, allowing independent removal and replacement. This segmentation enables easy maintenance and repair of the motor assembly without disassembling the entire support structure, while the modular design actually simplifies the overall system architecture

Inventive Principle:
Principle #1Segmentation
