Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If the shock wave generator is made small in size, then it becomes more portable and easier to operate, but heat dissipation capability deteriorates

Engineering Contradiction:

Improvesize of shock wave generatorVSAvoidheat dissipation capability

Core Design Contradiction:

Volume of moving objectVSTemperature

Solution Approach 1:

The generator is divided into modular components including a pump unit, treatment head, and control unit. The pump unit is separated from the treatment head, allowing the treatment head to remain small while the pump unit handles fluid circulation for heat dissipation.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A shock wave transmission medium (fluid) is introduced as an intermediary to transfer heat away from the disk. The fluid circulates through channels in the pump unit, absorbing heat from the metal membrane and transmitting it to the housing for dissipation.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Power

If a metal membrane is used for shock wave generation, then shock wave efficiency is improved, but heat generation increases

Engineering Contradiction:

Improveshock wave generation efficiencyVSAvoidheat generation

Core Design Contradiction:

PowerVSTemperature

Solution Approach 1:

The heat generated by the metal membrane during shock wave generation is converted from a harmful effect into a manageable parameter. The circulating fluid absorbs this heat, and the housing structure with its thermal mass and external surfaces dissipates the heat, transforming the problem of heat generation into a controlled thermal management process.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

Solution Approach 2:

A hydraulic system using shock wave transmission medium is implemented to manage heat. The pump unit circulates the fluid through channels that contact the metal membrane, using fluid dynamics to continuously remove heat during operation.

Inventive Principle:

Principle #29Pneumatics and hydraulics

3Temperature

If the metal plate is fully exposed to the shock wave transmission medium, then heat dissipation is maximized, but structural integrity and insulation may be compromised

Engineering Contradiction:

Improveheat dissipation efficiencyVSAvoidstructural integrity and insulation

Core Design Contradiction:

TemperatureVSStrength

Solution Approach 1:

The insulating thin elastic plate is designed with non-uniform properties: it provides full insulation in most areas while creating localized exposure zones where the metal membrane contacts the fluid. This local differentiation allows simultaneous achievement of insulation and heat dissipation.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

A thin elastic insulating plate is used instead of rigid insulation. This flexible film can be precisely configured to provide insulation where needed while creating controlled openings for heat dissipation, maintaining both structural integrity and thermal management.

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 solution effectively increases heat dissipation efficiency, preventing damage to the shock wave generating unit by rapidly removing heat generated during operation, particularly in smaller units.

Implementation Method 1

When an electric current is supplied to the high-voltage coil, a magnetic field is generated and drives the metal membrane in the shallow groove of the rubber membrane into vibration. Consequently, shock waves are produced in the water

Methodology Applied

Scientific EffectElectromagnetic induction: Electromagnetic Induction

Implementation Method 2

The accommodating cavity is filled with a shock wave transmission medium, which can circulate via the channel and is in contact with the exposed portion of the thin metal plate to facilitate dissipation of the heat generated by the disk during operation

AI summary

A shock wave generating unit includes a housing and a disk in the housing. The disk includes a vibration plate, which corresponds to a shock wave transmission member covering a first opening of the housing and includes an insulating thin elastic plate and a thin metal plate. The insulating thin elastic plate, with one side corresponding to the shock wave transmission member and the opposite side provided with the thin metal plate, has a hollow portion for partially exposing the thin metal plate and forms an accommodating cavity together with the exposed portion of the thin metal plate and the shock wave transmission member. A shock wave transmission medium can circulate through the accommodating cavity via a channel in the housing and is in contact with the exposed portion of the thin metal plate to facilitate dissipation of the heat generated by the disk during operation.
