Solution Overview

Problem

Existing portable illumination boxes for remote object display suffer from non-uniform illumination and dark zones, making it difficult to achieve high-quality remote viewing and manipulation of objects, especially those with reflecting surfaces.

Innovation Solution

A box design with a light-transmitting bottom and diffusing cover, where the entire envelope acts as a light guide, providing homogeneous illumination and allowing for manipulation through symmetrically positioned openings, ensuring light reaches the object from all directions and enabling faithful remote viewing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the box includes a large opening for object introduction and camera access, then ease of operation is improved, but illumination quality deteriorates due to dark zones

Engineering Contradiction:
Improveobject introduction and manipulationVSAvoidillumination uniformity
Core Design Contradiction:
Ease of operationVSIllumination intensity

Solution Approach 1:

The envelope is designed with differentiated optical properties: the cover and bottom use light-transmitting and diffusing materials to create uniform illumination, while the lateral sides use light-reflecting materials to redirect light onto the object. This local differentiation of material properties resolves the contradiction by providing both access openings and uniform illumination across different regions of the box.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The envelope acts as an intermediary light guide that distributes light uniformly throughout the housing. By using specific materials (light-transmitting cover, light-reflecting sides, light-diffusing bottom), the envelope mediates between the light sources and the object, ensuring uniform illumination even in the presence of access openings.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Illumination intensity

If light sources are arranged around the housing for uniform illumination, then illumination quality is improved, but device complexity increases

Engineering Contradiction:
Improveillumination uniformityVSAvoidlight source arrangement
Core Design Contradiction:
Illumination intensityVSDevice complexity

Solution Approach 1:

The envelope structure is merged with the illumination function. Instead of separate illumination devices, the envelope itself becomes the light guide through strategic material selection: light-transmitting cover, light-reflecting lateral sides, and light-diffusing bottom. This merging simplifies the overall device while achieving uniform illumination.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The envelope serves multiple functions simultaneously: it provides the housing structure, guides and distributes light uniformly, and the light-reflecting lateral sides actively contribute to illumination. This multi-functionality reduces device complexity by eliminating the need for separate illumination components.

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

3Strength

If the bottom is made opaque for structural integrity, then strength is improved, but illumination quality deteriorates due to dark zones

Engineering Contradiction:
Improvestructural integrityVSAvoidillumination uniformity
Core Design Contradiction:
StrengthVSIllumination intensity

Solution Approach 1:

The bottom is designed with a specific local quality: light-diffusing material that maintains structural integrity while transmitting and diffusing light uniformly. This resolves the contradiction by providing both structural strength and illumination quality through the bottom surface.

Inventive Principle:
Principle #3Local quality
