Solution Overview

Problem

Current curing lamps for windshield repairs are limited in their ability to effectively cure repair materials through glass or plastic surfaces, particularly when UV-blocking materials are present, and lack flexibility in positioning, which restricts access and efficiency during the repair process.

Innovation Solution

A curing lamp apparatus with a suction cup base and a flexible neck, featuring a lamp element that emits UV light at multiple wavelengths, including 365 and 395 nanometers, allowing for flexible positioning and the ability to cure resin from the opposite side of the windshield, and incorporating a heat sink for cooling and a rechargeable battery with control circuitry for timed operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single wavelength UV light source is used, then the device complexity is reduced, but the ability to cure resin through UV-blocking windshield materials is insufficient

Engineering Contradiction:
Improveability to cure resin through different windshield materialsVSAvoidlamp element structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines multiple UV light sources with different wavelengths (365nm and 395nm) into a single lamp element assembly. This merging allows the device to emit multiple wavelengths simultaneously, enabling it to cure resin through various windshield materials including UV-blocking materials, while maintaining a unified structural design that manages complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The lamp element is designed with multi-functionality by incorporating both 365nm and 395nm UV LEDs. The 365nm wavelength cures resin directly, while the 395nm wavelength penetrates UV-blocking windshield materials to cure resin from the exterior. This universal design allows a single device to handle multiple curing scenarios and different windshield types.

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

2Productivity

If the lamp is positioned close to the crack for effective curing, then the curing efficiency is improved, but the accessibility to hard-to-reach areas is reduced

Engineering Contradiction:
Improvecuring efficiencyVSAvoidaccessibility to crack locations
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The patent incorporates a flexible neck mechanism that allows the lamp head to be dynamically positioned and angled. This dynamic positioning capability enables the operator to reach difficult-to-access crack locations while maintaining the lamp head in optimal proximity to the resin for effective curing. The flexibility resolves the contradiction between needing close positioning for efficiency and needing accessibility for operation.

Inventive Principle:
Principle #15Dynamics

3Reliability

If UV light at 365nm is used for curing, then the curing effectiveness is improved, but sunlight damage to vehicle interior occurs

Engineering Contradiction:
Improvecuring effectivenessVSAvoidsunlight damage to vehicle interior
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent applies local quality by using different wavelengths for different purposes: 365nm UV light is directed through the flexible neck to the crack location for effective resin curing, while 395nm UV light is emitted toward the windshield interior to prevent UV-blocking material degradation. This localized application of different wavelengths ensures both curing effectiveness and protection of the vehicle interior from harmful UV exposure.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The flexible neck acts as an intermediary that directs and controls the path of UV light. It enables the 365nm curing light to reach the resin through precise positioning while allowing the 395nm protective light to be directed toward the windshield interior, thus mediating between the curing function and the protective function to prevent sunlight damage.

Inventive Principle:
Principle #24Intermediary (Mediator)
