Solution Overview

Problem

Service vehicles often face inadequate lighting in cargo or back spaces due to shadows from the body obstructing ceiling lamps, and existing solutions are either costly or difficult to install efficiently.

Innovation Solution

A modular service vehicle illumination system with multiple LED light sources connected via electric current means, allowing flexible arrangement and easy installation, featuring a switch for remote control and energy-saving features.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If a ceiling lamp is used to illuminate the cargo or back space, then the overall illumination is improved, but shadows are created by the person's body and module units making it hard to see work areas

Engineering Contradiction:
Improveoverall illuminationVSAvoidshadows
Core Design Contradiction:
Illumination intensityVSObject-affected harmful factors

Solution Approach 1:

The illumination system is divided into multiple separate light sources distributed throughout the cargo space rather than a single ceiling lamp. Each light source independently illuminates specific areas, creating a segmented lighting approach that reduces shadowing effects while maintaining overall illumination.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If an extra light source is placed within the cargo or back space near a door for easy control, then the switchability is improved, but the light is shadowed once a person enters the cargo space

Engineering Contradiction:
Improveswitch controlVSAvoidlight coverage
Core Design Contradiction:
Ease of operationVSIllumination intensity

Solution Approach 1:

The switch is relocated from inside the cargo space to the driver's cab, representing a spatial transition from one dimension (cargo space interior) to another (driver's cab). This allows the switch to be positioned where it can be easily accessed without being in the path of light or shadowed by the person's body.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Adaptability or versatility

If conventional light systems with separated switches are implemented, then the flexibility of light placement is improved, but the installation becomes time-consuming and costly

Engineering Contradiction:
Improvelight placement flexibilityVSAvoidinstallation time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The switch function is merged with the door assembly rather than being a separate component. The door assembly already exists as a structural element, and integrating the switch into it eliminates the need for separate switch mounting, reducing installation time and cost while maintaining placement flexibility.

Inventive Principle:
Principle #5Merging (Combining)

4Object-affected harmful factors

If multiple light sources are distributed throughout the cargo space for improved illumination, then the shadow reduction is improved, but the system complexity increases

Engineering Contradiction:
Improveshadow reductionVSAvoidsystem complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

Multiple light sources are integrated into existing module units that serve dual purposes: they provide structural/storage functions and simultaneously house the illumination components. This multi-functionality approach increases shadow reduction capability while minimizing the increase in system complexity by reusing existing structures.

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