Solution Overview

Problem

Existing lighting systems face challenges such as difficult armature mounting, especially from below, and the need for frequent replacements due to obsolete light sources, which can be costly and environmentally undesirable, particularly in large installations like hotels.

Innovation Solution

A modular lighting device with a main body featuring a threaded outer surface for easy insertion into building structures, allowing for secure mounting without pre-cut threads and enabling the use of new light sources with existing armatures, along with a reflector and attachment means to prevent entanglement of wires and facilitate installation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional mounting systems are used, then armatures can be mounted in building structures, but the mounting process becomes very challenging and time-consuming

Engineering Contradiction:
Improvemounting easeVSAvoidmounting time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The patent inverts the traditional mounting approach by providing threading on the outer surface of the armature body instead of requiring pre-cut threads in the building structure. This allows the armature to be screwed directly into the building structure from below, reversing the conventional top-down mounting method and significantly simplifying the installation process

Inventive Principle:
Principle #13The other way round (Inversion)

Solution Approach 2:

The armature body includes an integrated threaded outer surface that enables self-contained mounting without requiring separate mounting components or complex assembly steps. The armature serves its own mounting function through the built-in threading, eliminating the need for additional mounting hardware and reducing installation complexity

Inventive Principle:
Principle #25Self-service

2Use of energy by moving object

If old lighting systems are replaced with new energy optimized light sources, then energy efficiency improves, but the cost increases significantly

Engineering Contradiction:
Improveenergy efficiencyVSAvoidreplacement cost
Core Design Contradiction:
Use of energy by moving objectVSLoss of substance

Solution Approach 1:

The patent separates the light source from the armature body, allowing the energy-efficient LED module to be replaced independently while retaining the existing armature housing and mounting infrastructure. This modular segmentation enables upgrading only the energy-consuming component rather than replacing the entire lighting assembly

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The design enables discarding only the obsolete light source while recovering and reusing the armature body, mounting threads, and structural components. This selective replacement approach reduces waste and lowers the overall cost of upgrading to energy-efficient lighting

Inventive Principle:
Principle #34Discarding and recovering

3Ease of operation

If armatures are mounted from above the sealing, then mounting can be performed, but the method becomes very challenging

Engineering Contradiction:
Improvemounting easeVSAvoidmounting complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent enables mounting from below by providing threading on the outer surface of the armature body, allowing installation workers to approach from the accessible below side rather than requiring work from above the sealing. This inverted mounting direction simplifies the process by working from the more accessible location

Inventive Principle:
Principle #13The other way round (Inversion)

Solution Approach 2:

The threaded outer surface acts as an intermediary mechanism that facilitates mounting from below by providing a screw-threaded interface between the armature and the building structure. This intermediary threading system enables simple rotational insertion from the below side without requiring complex clamping or sealing mechanisms

Inventive Principle:
Principle #24Intermediary (Mediator)
