Solution Overview

Problem

Conventional in-ground linear lighting systems are difficult to install and susceptible to water damage due to their outdoor exposure, requiring special tools and hardware.

Innovation Solution

A lighting system featuring a flexible clip and hinge structure for easy assembly and disassembly, along with a drainage system to prevent water accumulation, allowing the linear light fixture to be securely mounted within a blockout structure and ensuring protection against water damage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional in-ground linear lighting systems are used, then the lighting function is provided, but the installation process becomes difficult and time-consuming due to requiring special tools and hardware

Engineering Contradiction:
ImproveInstallation easeVSAvoidInstallation time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The lighting system is divided into separate modular components: a linear lighting fixture and a linear blockout structure. These segments can be independently manufactured and then easily assembled together through the hinge structure and fastening components, eliminating the need for complex on-site assembly procedures and special installation tools.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The hinge structure enables dynamic movement during installation, allowing the linear lighting fixture to be rotated from a first position to a second position to engage with the blockout structure. This dynamic assembly mechanism simplifies the installation process compared to rigid, fixed-configuration systems that would require precise alignment and special tools.

Inventive Principle:
Principle #15Dynamics

2Reliability

If conventional in-ground linear lighting systems are used, then the lighting function is provided, but the system becomes susceptible to water damage due to outdoor exposure

Engineering Contradiction:
ImproveWater damage resistanceVSAvoidWater exposure
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The potential water damage problem is extracted and addressed by implementing a dedicated drainage system within the linear blockout structure. Drainage channels and/or holes are integrated into the blockout structure to actively remove water that may enter the installation cavity, preventing water accumulation and protecting the lighting fixture from water damage.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The linear blockout structure serves as an intermediary protective element between the outdoor environment and the lighting fixture. It provides a physical barrier and incorporates drainage mechanisms that mediate water exposure, allowing the fixture to remain protected while still functioning in outdoor environments.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Stability of the object's composition

If the linear light fixture is securely mounted in the blockout structure, then installation stability is improved, but the ability to perform maintenance or replacements becomes difficult

Engineering Contradiction:
ImproveAssembly stabilityVSAvoidMaintenance accessibility
Core Design Contradiction:
Stability of the object's compositionVSEase of repair

Solution Approach 1:

The hinge structure provides a dynamic connection that secures the lighting fixture during normal operation while enabling controlled movement for maintenance. The fastening components can be engaged to provide stable mounting, then disengaged using a disassembly tool to allow the fixture to be rotated and removed for maintenance or replacement, and re-engaged afterward.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system incorporates a disassembly tool that can be inserted through openings in the blockout structure to engage and disengage the fastening components. This self-service mechanism allows maintenance personnel to access and service the lighting fixture without requiring complete disassembly of the blockout structure or specialized equipment, balancing security with maintainability.

Inventive Principle:
Principle #25Self-service

AI summary

A lighting system includes a linear light fixture and a linear blockout structure. The linear blockout structure includes a chamber in which the linear light fixture is mountabie and side walls on opposite sides of the chamber engageable by flange portions of the linear light fixture when the linear light fixture and linear blockout structure are assembled together. A hinge structure includes first and second hinge components engaging each other such that when the linear blockout structure and linear lighting fixture are being assembled, they are rotatable with respect to each other at the hinge structure. First and second fastening components engage each other to hold the linear blockout structure and linear lighting fixture assembled together with the linear light fixture being disposed within the chamber of the linear blockout structure.
