Solution Overview

Problem

Fixed light sources in storage enclosures, such as freezer chests, often fail to adequately illuminate all areas due to configuration or interference from objects, leading to inadequate lighting in certain regions.

Innovation Solution

A modular light source assembly with an adjustable position, using magnetic attachments and a flexible electrical conduit, allowing the light source to be removably attached to various surfaces within the enclosure, ensuring illumination of selected locations within the enclosure interior.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If fixed light sources are used in storage enclosures, then installation is simple, but illumination coverage is inadequate

Engineering Contradiction:
Improveillumination coverageVSAvoidlight source positioning system
Core Design Contradiction:
Illumination intensityVSDevice complexity

Solution Approach 1:

The patent applies the dynamics principle by making the light source movable rather than fixed. The light source can be repositioned along the interior surfaces of the storage enclosure using magnetic attachment mechanisms, allowing it to adapt to different illumination needs and enclosure configurations. This dynamic positioning capability resolves the contradiction by providing both flexible illumination coverage and relatively simple installation through magnetic attachment.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent implements universality by designing a light source system that can serve multiple positions and functions within the storage enclosure. The movable light source can be attached at various locations to illuminate different areas, making a single light source capable of performing the function of multiple fixed light sources. This multi-functionality improves illumination coverage without proportionally increasing the number of components.

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

2Adaptability or versatility

If light sources are repositionable to illuminate selected locations, then illumination flexibility is improved, but device complexity increases

Engineering Contradiction:
Improvelight source positioning flexibilityVSAvoidpositioning mechanism
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies mechanics substitution by replacing complex mechanical positioning systems with magnetic attachment mechanisms. Instead of using motors, gears, or other complex mechanical systems to move the light source, the invention uses magnetic fields to enable simple attachment and detachment at various positions. This substitution achieves high positioning flexibility while keeping the device complexity low.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent uses magnetic fields as an intermediary between the light source and the enclosure surfaces. The magnetic attachment mechanism acts as an intermediary that enables easy positioning without direct mechanical connection. This intermediary approach allows the light source to be repositioned flexibly while maintaining simplicity in the positioning mechanism.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Illumination intensity

If fixed light sources are installed, then installation is straightforward, but illumination adequacy deteriorates due to object interference

Engineering Contradiction:
Improvelighting adequacyVSAvoidinstallation simplicity
Core Design Contradiction:
Illumination intensityVSEase of operation

Solution Approach 1:

The patent applies dynamics by enabling the light source to be repositioned after installation. When objects are placed in the storage enclosure that block fixed light sources, the user can move the light source to alternative positions to maintain adequate illumination. This dynamic adaptability preserves lighting adequacy while the magnetic attachment system keeps installation and repositioning simple.

Inventive Principle:
Principle #15Dynamics

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The solution provides flexible and effective illumination of specific areas within storage enclosures, enhancing lighting coverage and accessibility by allowing the light source to be positioned optimally, regardless of the enclosure's configuration or object interference.

Implementation Method 1

The light source can include an attachment feature by means of which the light source can be both removably attachable at the one of the one or more enclosure interior surfaces at the base station and removably attachable at the one or more enclosure interior surfaces away from the base station
