Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the cleaning pump rotates at high speed to provide high pressure and large flow rate for cleaning, then the cleaning effect is improved, but the vibration and noise generated by the cleaning pump increase, affecting driver and passenger comfort

Engineering Contradiction:
Improvecleaning effectVSAvoidvibration and noise
Core Design Contradiction:
ProductivityVSObject-generated harmful factors

Solution Approach 1:

The patent introduces an elastic positioning sleeve as an intermediary component between the cleaning pump and the cleaning liquid tank. This elastic positioning sleeve acts as a vibration isolation element that absorbs and dampens the vibrations generated by the high-speed rotating cleaning pump, preventing them from being transmitted to the cleaning liquid tank and amplified. The elastic material of the positioning sleeve provides vibration damping while maintaining the structural connection needed for the pump to function effectively.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Stability of the object's composition

If the cleaning pump is rigidly fixed to the cleaning liquid tank for stable positioning, then the positioning stability is improved, but the vibration transmission to the cleaning liquid tank increases, causing greater vibration and noise

Engineering Contradiction:
Improvepositioning stabilityVSAvoidvibration transmission
Core Design Contradiction:
Stability of the object's compositionVSObject-generated harmful factors

Solution Approach 1:

The patent employs an elastic positioning sleeve made of flexible elastic material to replace rigid fixation between the cleaning pump and the cleaning liquid tank. This flexible elastic component provides positioning stability through its elastic properties while simultaneously absorbing vibrations. The elastic positioning sleeve can deform elastically under vibration loads, isolating the cleaning liquid tank from the high-frequency vibrations generated by the pump motor, thus reducing noise and vibration transmission.

Inventive Principle:
Principle #30Flexible shells and thin films

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The system effectively suppresses vibrations and reduces noise by damping the high-speed rotation-induced vibrations, enhancing comfort and reducing noise interference.

Implementation Method 1

an elastic positioning member is arranged on a top cover of the cleaning pump; a positioning hole, which corresponds to the elastic positioning member, is provided in the center of the elastic positioning sleeve, so that the elastic positioning sleeve is fixed to the elastic positioning member
