Solution Overview

Problem

Existing light fixture mounting systems lack the ability to provide multiple tilt angles and orientations, limiting the flexibility and precision in adjusting the direction of illumination.

Innovation Solution

A mounting arm system comprising a first and second arm portion, each capable of rotational orientation, allowing the light fixture to be positioned in multiple tilt positions by changing the relative angles of these arms, thereby adjusting the illumination pattern.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single fixed mounting arm is used, then the structure is simple and stable, but the ability to adjust illumination direction is limited

Engineering Contradiction:

Improveadjustment of illumination directionVSAvoidmounting arm structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The mounting arm is divided into multiple segments (first arm portion, second arm portion, intermediate arm portion) that can be independently rotated relative to each other. Each segment can assume multiple rotational positions, allowing the light fixture to be adjusted to different tilt angles and orientations while maintaining a relatively simple overall structure.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The mounting arm incorporates rotational joints and coupling mechanisms that allow dynamic adjustment of the arm segments between multiple fixed rotational positions. This enables the system to transition between different illumination directions while maintaining structural stability at each positioned state.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If multiple arm portions with rotational capability are used, then multiple tilt angles are achieved, but the device complexity increases

Engineering Contradiction:

Improvenumber of tilt positionsVSAvoidmounting arm configuration

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The mounting arm is segmented into multiple portions (first arm portion, second arm portion, intermediate arm portion) connected by rotational joints. Each segment can be independently rotated to different positions, multiplying the number of possible tilt angles. For example, with two rotational positions per segment, up to eight different tilt positions are achieved (2^3 = 8).

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The mounting arm design allows a single structure to perform multiple functions: it provides mechanical support, enables multi-position angular adjustment, and maintains stable mounting to the support structure. The same arm portions serve both structural and adjustment functions.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

An illustrative mounting arm for a light fixture provides multiple tilt angles based on the selected orientation of components of the mounting arm. The mounting arm includes a first and second arm portion, each having opposite ends oriented at different relative angles to provide the multiple tilt angles for the light. A support end arm or second arm portion connects directly or indirectly to a wall or other support structure. An intermediate or first arm portion couples between the second arm portion and a mounting pad portion of the light fixture. Each of the first and second arm portions are rotatable in orientation, thus changing the orientation of the angle ends, each combination of possible arm portion orientations displacing the light fixture and therefore the illumination pattern at a different elevation angle relative to the support structure.
