Solution Overview

Problem

Existing driving lights face challenges such as difficulty in mounting on various vehicles, susceptibility to theft, exposure to dirt and grime, impact on air resistance and fuel consumption, visibility issues, and limited adjustability and efficiency due to external mounting, as well as delayed illumination in Xenon HID lamps.

Innovation Solution

A lighting device designed for temporary mounting on a vehicle's windshield using suction cups, equipped with a Xenon HID lamp, adjustable reflectors, wireless control signals, and a shutter for immediate full illumination, allowing easy relocation and minimizing theft and environmental impact.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If driving lights are mounted externally on the vehicle, then lighting efficiency is improved, but air resistance increases and fuel consumption increases

Engineering Contradiction:

Improvelighting efficiencyVSAvoidfuel consumption

Core Design Contradiction:

Illumination intensityVSLoss of energy

Solution Approach 1:

The patent inverts the conventional mounting approach by placing driving lights inside the vehicle cabin rather than externally on the vehicle body. This inversion eliminates the adverse aerodynamic effects of external mounting while maintaining effective illumination through strategic positioning near the windshield and use of reflective surfaces.

Inventive Principle:

Principle #13The other way round (Inversion)

2Illumination intensity

If driving lights are mounted externally on the vehicle, then lighting coverage is improved, but susceptibility to theft and dirt increases

Engineering Contradiction:

Improvelighting coverageVSAvoidtheft and dirt exposure

Core Design Contradiction:

Illumination intensityVSObject-affected harmful factors

Solution Approach 1:

The patent inverts the conventional mounting approach by placing driving lights inside the vehicle cabin rather than externally on the vehicle body. This inversion eliminates exposure to theft, dirt, and grime while maintaining effective illumination through strategic positioning near the windshield and use of reflective surfaces.

Inventive Principle:

Principle #13The other way round (Inversion)

3Object-affected harmful factors

If driving lights are mounted inside the windshield, then theft risk is reduced, but visibility and safety equipment function may be impaired

Engineering Contradiction:

Improvetheft riskVSAvoidvisibility and safety equipment function

Core Design Contradiction:

Object-affected harmful factorsVSReliability

Solution Approach 1:

The patent applies local quality by positioning driving lights in specific locations inside the windshield area where they provide effective illumination without blocking the driver's view or interfering with airbag deployment. The lighting units are strategically placed to achieve local optimization of both security and safety.

Inventive Principle:

Principle #3Local quality

4Illumination intensity

If Xenon HID lamps are used, then illumination quality is improved, but delayed full illumination occurs after switching on

Engineering Contradiction:

Improveillumination qualityVSAvoidstartup delay

Core Design Contradiction:

Illumination intensityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by incorporating a pre-heating circuit that activates before the Xenon HID lamp is fully switched on. This pre-heating process prepares the lamp for immediate full illumination, eliminating the dangerous delay that would otherwise occur when the driver activates the driving lights.

Inventive Principle:

Principle #10Preliminary action

AI summary

Lighting device for emission of light through a windshield of a vehicle consisting of at least one lighting unit intended to be temporarily mounted on the inside of a windshield with at least one fastening device. The lighting unit consists of at least one reflector, one lamp and at least one seal between the lighting unit and the windshield. The lighting unit is powered by electric energy and the lamp's on and off switch is controlled by at least one sensor designed to detect turned on high-beams which wirelessly sends control signals to the lighting unit. The lighting device consists of a function with which the light's illumination can be adjusted and with which the light can be completely or partially blocked.
