Solution Overview

Problem

Existing systems for creating a liquid jet on the outer region of a motor vehicle lack the ability to efficiently convey and control the liquid jet to a container, failing to provide a dynamic and adjustable water fountain effect with integrated lighting and remote control capabilities.

Innovation Solution

A liquid device comprising a pump-driven liquid outlet and inlet system with adjustable trajectories, illuminated by a light source, and controlled by actuators and automated switch units, allowing for remote operation and energy-efficient operation based on sensors or timers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If a liquid jet is discharged from the front of the motor vehicle to create a water fountain effect, then visual appeal is enhanced, but liquid is lost and requires frequent refilling

Engineering Contradiction:
Improvevisual appealVSAvoidliquid loss
Core Design Contradiction:
Illumination intensityVSLoss of substance

Solution Approach 1:

The liquid container positioned at the rear of the vehicle receives the discharged liquid jet and feeds it back into the tank via a conduit, creating a closed-loop system that recycles liquid and eliminates frequent refilling while maintaining the water fountain effect

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

Instead of allowing the liquid jet to be wasted after discharge, the system recovers the liquid by capturing it in the rear container and returning it to the tank, transforming a lossful process into a sustainable cycle

Inventive Principle:
Principle #34Discarding and recovering

2Illumination intensity

If multiple liquid jets are discharged sequentially to enhance the water fountain effect, then visual appeal is improved, but liquid consumption increases

Engineering Contradiction:
Improvevisual appealVSAvoidliquid consumption
Core Design Contradiction:
Illumination intensityVSQuantity of substance

Solution Approach 1:

The feedback system ensures continuous liquid circulation, allowing multiple sequential jets to be discharged without proportionally increasing liquid consumption, as the same liquid is repeatedly circulated through the system

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

The system can discharge multiple liquid jets in sequential periods while the feedback mechanism continuously recycles the liquid, enabling periodic visual effects without continuous liquid consumption

Inventive Principle:
Principle #19Periodic action

3Stability of the object's composition

If the liquid container is positioned at the rear of the vehicle to receive the liquid jet, then the liquid circulation system is completed, but the trajectory control becomes more complex

Engineering Contradiction:
Improveliquid circulationVSAvoidtrajectory control
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The liquid outlet is designed with adjustable trajectory capabilities, allowing dynamic adaptation of the liquid jet path to reliably reach the rear container while maintaining system simplicity through mechanical adjustment rather than complex control mechanisms

Inventive Principle:
Principle #15Dynamics

AI summary

A liquid device generates a liquid jet on an outer region of a motor vehicle. The liquid device includes a liquid outlet via which the liquid jet, generated by a pump and fed from a tank, emerges in the outer region of the motor vehicle. The liquid device also includes a liquid container having a liquid inlet in which the liquid jet emerging from the liquid outlet can be received in the outer region of the motor vehicle and which is connected via a conduit to the tank.
