Solution Overview

Problem

In paint repair work on motor vehicles, visual inspections of painted surfaces under natural daylight conditions are challenging due to variations in outdoor light conditions, and existing inspection tools may cause scratches or damage to surfaces during use.

Innovation Solution

A daylight portable lamp with an elastic sleeve surrounding the light-exit opening, made from rubber-elastic material, which reduces the risk of scratches and damage, and includes a rigid-plastic housing with a detachable cover plate and adjustable light intensity for optimal inspection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If a rigid housing is used for the light-exit opening, then structural stability is improved, but the risk of scratches or dents being introduced into the surface increases

Engineering Contradiction:

Improvestructural stabilityVSAvoidrisk of scratches or dents

Core Design Contradiction:

Stability of the object's compositionVSObject-affected harmful factors

Solution Approach 1:

The patent applies a flexible sleeve made of rubber-elastic material that surrounds the light-exit opening. This flexible shell replaces the rigid housing in direct contact with the painted surface, allowing the structure to be stable while the flexible material prevents scratches and dents during inspection operations.

Inventive Principle:

Principle #30Flexible shells and thin films

2Stability of the object's composition

If a rigid housing is used for the light-exit opening, then structural stability is improved, but the portable lamp is more susceptible to damage from impacts or drops

Engineering Contradiction:

Improvestructural stabilityVSAvoidprotection from impact damage

Core Design Contradiction:

Stability of the object's compositionVSReliability

Solution Approach 1:

The flexible rubber-elastic sleeve serves as a protective cushion that is already in place before any impact occurs. It absorbs the energy of accidental drops or strikes against objects, protecting both the painted surface and the portable lamp structure from damage.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

3Stability of the object's composition

If a rigid housing is used for the light-exit opening, then structural stability is improved, but the portable lamp slides more easily on sloping surfaces

Engineering Contradiction:

Improvestructural stabilityVSAvoidstability on sloping surfaces

Core Design Contradiction:

Stability of the object's compositionVSEase of operation

Solution Approach 1:

The flexible rubber-elastic sleeve increases the coefficient of friction between the portable lamp and sloping surfaces. This flexible material provides better grip and prevents sliding during operation, while the rigid housing maintains structural integrity.

Inventive Principle:

Principle #30Flexible shells and thin films

4Stability of the object's composition

If artificial light is used for inspection in enclosed areas, then constant and reproducible light conditions are achieved, but the light spectrum may not accurately represent natural daylight

Engineering Contradiction:

Improvelight condition consistencyVSAvoidcolor accuracy

Core Design Contradiction:

Stability of the object's compositionVSMeasurement precision

Solution Approach 1:

The patent uses a LED lighting element with specifically engineered spectral characteristics that replicate natural daylight. By adjusting the LED parameters to match daylight spectrum, the system achieves both consistency and accuracy in color representation for inspection purposes.

Inventive Principle:

Principle #35Parameter changes

Implementation Method 2

the portable lamp itself is also protected from damage by the damping effect of the elastic sleeve if the head part is inadvertently struck against an object or if the portable lamp is accidentally dropped

Methodology Applied

Scientific EffectDamping: Damping

Implementation Method 3

the elastic material increases the static friction, for example in comparison with a rigid plastic

Methodology Applied

Scientific EffectFriction: Friction
