Solution Overview

Problem

Conventional linear lighting systems lack adjustability in length, limiting their flexibility to customize lighting solutions according to specific needs and dimensions, necessitating the use of multiple prefabricated boards or boards of different lengths.

Innovation Solution

A lighting system with a telescoping reflector mechanism that allows for adjustable length by connecting first and second housing portions via a mounting bracket, enabling extension and retraction through a guide rail system and housing trims, allowing seamless length adjustment without compromising efficiency or performance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If fixed configurations of LED boards are used, then manufacturing simplicity is improved, but length adjustability deteriorates

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidlength adjustability
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The lighting system is divided into multiple modular housing portions (first housing portion, second housing portion) that can be independently manufactured and then assembled in different configurations. Each housing portion contains its own LED board and reflector assembly, allowing the system to be segmented into standardized units that maintain manufacturing simplicity while enabling length customization through varying the number of modules.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system transitions from a static fixed-length design to a dynamic adjustable-length configuration through the telescoping reflector mechanism. The telescoping reflector can extend and retract relative to the housing portions, allowing the effective lighting length to be adjusted after manufacturing without requiring different fixed configurations for each application.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If multiple prefabricated boards are combined to achieve varying lengths, then length flexibility is improved, but device complexity increases

Engineering Contradiction:
Improvelength flexibilityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Multiple housing portions are merged into a single integrated assembly through the telescoping reflector mechanism that spans across them. The mounting bracket unifies the reflector assemblies from different housing portions, creating a cohesive lighting system that functions as one unit rather than separate boards, thereby reducing overall system complexity while maintaining length flexibility.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The standardized housing portion design serves multiple functions: it provides structural support, houses LED components, contains a reflector, and interfaces with adjacent modules through universal mounting features. This multi-functionality reduces the need for additional specialized components when combining multiple boards, thereby limiting the increase in device complexity despite achieving length flexibility.

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

3Adaptability or versatility

If telescoping reflector mechanism is added for length adjustment, then length adjustability is improved, but structural complexity increases

Engineering Contradiction:
Improvelength adjustabilityVSAvoidstructural complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The telescoping reflector is nested within the housing portions, with the reflector assembly fitting inside the structural envelope of the housing. This nesting arrangement allows the adjustable mechanism to be contained within the existing structural boundaries without requiring external support structures, thereby minimizing the increase in structural complexity while achieving length adjustability.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The mounting bracket acts as an intermediary component that connects the telescoping reflector to the housing portions. Rather than directly modifying the housing structure to accommodate the telescoping mechanism, the mounting bracket serves as a mediator that simplifies the structural integration, reducing the overall structural complexity increase.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A lighting system including a first and second housing portion, each defining two sidewalls and an intersecting crossbar connecting the two sidewalls. The lighting system has housing trims affixed to an exterior of the sidewalls of the first and second housing portions. Further, there is a first direct extrusion reflector positioned within and connected to the interior of the sidewalls of the first housing portion, and a second direct extrusion reflector positioned within and connected to the interior of the sidewalls of the second housing portion. A telescoping reflector is connected to the first direct extrusion reflector and laterally offset therefrom. A light shield is connected to the first housing portion and configured to guide along the housing trim of the second housing portion, enabling the lighting system to extend and retract in length.
