Solution Overview

Problem

The installation of lights in a building is labor-intensive and time-consuming due to the need for manual alignment and placement of downlight fixtures.

Innovation Solution

A downlight laser-jig system that includes a housing structure with a laser, handles for lifting, and magnets or spring clips to hold the jig in place, facilitating the alignment and installation of multiple downlight fixtures efficiently.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual alignment and placement methods are used for downlight fixtures, then installation flexibility is maintained, but installation time and labor intensity increase significantly

Engineering Contradiction:

Improveinstallation speedVSAvoidinstallation tool complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent combines the alignment tool (laser level) and the positioning jig into a single integrated device. The laser module is mounted within the jig housing, allowing simultaneous alignment and positioning functions to be performed by one tool rather than requiring separate manual operations with multiple tools.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The jig acts as an intermediary device between the installer and the downlight fixture. It provides a standardized interface with clamping mechanisms that automatically engage with the fixture mounting brackets, eliminating the need for manual alignment and placement while ensuring precise positioning.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Measurement precision

If traditional manual installation methods are used, then tool simplicity is maintained, but alignment precision deteriorates

Engineering Contradiction:

Improvealignment precisionVSAvoidtool structure complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent replaces manual visual alignment methods with an automated laser-based alignment system. The laser module projects reference lines that guide the positioning of downlight fixtures, providing precise alignment without requiring the installer to manually measure and calculate positions.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The jig is designed as a universal tool that can accommodate multiple types of downlight fixtures through adjustable clamping mechanisms. The same device performs both alignment (via laser) and positioning (via mechanical clamping), eliminating the need for different tools for different functions.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Loss of time

If installers frequently move between ceiling and ground levels, then tool portability is maintained, but installation time increases

Engineering Contradiction:

Improveinstallation timeVSAvoidinstaller mobility

Core Design Contradiction:

Loss of timeVSEase of operation

Solution Approach 1:

The patent enables installers to perform alignment and positioning operations at ceiling level without repeatedly moving to ground level. The laser module and jig can be positioned and operated from the ceiling, creating an equipotential working condition where all critical operations can be performed from a single location.

Inventive Principle:

Principle #12Equipotentiality

4Productivity

If multiple separate tools are used for alignment and positioning, then tool simplicity is maintained, but installation efficiency decreases

Engineering Contradiction:

Improveinstallation efficiencyVSAvoidintegrated tool complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A method, system, and apparatus for light fixture installation using a downlight laser jig. The downlight laser jig can have a housing structure to house a laser. The housing structure can have two or more walls, and a floor for a laser to sit in the housing structure. The housing structure can have one or more handles to assist in a lifting of the downlight laser jig. The housing structure can have at least one of 1) two or more magnets, 2) two or more spring clips, and 3) any combination of both to hold the downlight laser jig in place and support a weight of the downlight laser jig and the laser during an installation process for a series of downlight fixtures. The downlight laser jig and the laser combine to assist in aligning and installing the series of downlights fixtures in a ceiling.
