Solution Overview

Problem

Conventional luminaires are difficult to manufacture, install, and adjust, and they lack versatility in providing desired lighting outputs.

Innovation Solution

A luminaire base with a fixing plate and mounting collar system that includes an internal thread and external thread interaction for secure attachment, along with a grub screw to prevent rotation, and a head attachment that allows for adjustable light direction using an O-ring and rotatable components, enabling easy installation and adjustment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional luminaire mounting methods are used, then the luminaire can be attached to the panel, but the installation and adjustment process becomes complex and difficult

Engineering Contradiction:
Improveease of installationVSAvoidmounting complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The mounting system is divided into separate functional components: a fixing plate with internal threads for panel attachment, a mounting collar with external threads for securing the luminaire, and a grub screw for rotation prevention. This segmentation allows each component to perform its specific function independently, simplifying the overall installation process while reducing mounting complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The fixing plate serves multiple functions: it provides attachment points to the panel, contains internal threads for the mounting collar, and includes a hole for the grub screw. This multi-functionality reduces the number of separate components needed, thereby simplifying installation while maintaining system integrity.

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

2Reliability

If a secure mounting system is implemented with threads and screws, then the luminaire is firmly attached, but the manufacturing process becomes more complex

Engineering Contradiction:
Improvemounting securityVSAvoidmanufacturing simplicity
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The internal threads are integrated directly into the fixing plate structure, and the grub screw hole is incorporated into the same component. This merging of functions into a single fixing plate reduces the number of separate parts that need to be manufactured and assembled, thereby simplifying the manufacturing process while ensuring reliable mounting security.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The threaded features and grub screw hole are built into the fixing plate itself, allowing the component to provide its own mounting and securing mechanisms without requiring additional separate parts. This self-service approach reduces manufacturing complexity while maintaining secure attachment.

Inventive Principle:
Principle #25Self-service
