Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional adapter accessories are used to adapt to different screw hole patterns, then the light fixture can be mounted to various electrical junction boxes, but the installation complexity and time increase

Engineering Contradiction:

Improveadaptability to different junction box configurationsVSAvoidnumber of adapter hardware pieces

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The mounting bracket is designed with multiple mounting members that can accommodate different screw hole patterns and junction box configurations through a single universal design, eliminating the need for separate adapter accessories for each configuration type

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent combines the functions of multiple adapter accessories (adapter rings, mounting bars, swivel bars) into a single integrated mounting bracket assembly that performs all adaptation functions simultaneously

Inventive Principle:

Principle #5Merging (Combining)

2Manufacturing precision

If multiple adapter accessories are used to align the light fixture, then proper vertical alignment can be achieved, but the installation time and cost increase

Engineering Contradiction:

Improvevertical alignment precisionVSAvoidinstallation time

Core Design Contradiction:

Manufacturing precisionVSLoss of time

Solution Approach 1:

The mounting bracket is pre-configured with multiple mounting members positioned to accommodate different screw hole patterns, so that proper alignment is achieved automatically during installation without requiring time-consuming adjustments or multiple separate adapters

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The mounting bracket self-adapts to different junction box configurations through its multiple mounting members, automatically achieving proper vertical alignment without requiring the installer to manually adjust or select from multiple separate adapter components

Inventive Principle:

Principle #25Self-service

3Adaptability or versatility

If various adapter hardware pieces are supplied with the light fixture, then the fixture can be adapted to different electrical junction boxes, but the device complexity and number of parts increase

Engineering Contradiction:

Improvecompatibility with different junction box typesVSAvoidnumber of hardware pieces

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The single mounting bracket assembly performs the functions of multiple separate adapter hardware pieces by incorporating multiple mounting members that can interface with different screw hole patterns and junction box types

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

An alignable single-step mechanical/electrical mounting assembly includes an interior mounting bracket that is operable to be rotationally selectively securable to the interior of the mounting cover so that an electrical device coupled to the mounting cover will be aligned with a wall or ceiling after the second half of the mechanical couple mates with the first half of the mechanical couple and the second half of the electrical couple electrically couples with the first half of the electrical couple.
