Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If LEDs are used to replace conventional light sources, then energy efficiency is improved, but light direction and focus become difficult to control

Engineering Contradiction:

Solution Approach 1:

The LED array is divided into multiple independently adjustable LED modules, each with its own optic. This segmentation allows individual control of light direction for each module, solving the problem of difficult light direction control while maintaining the energy efficiency of LED technology.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The LED modules are made dynamically adjustable through rotational mechanisms that allow each module to be independently oriented. This dynamic adjustability enables precise control over light direction and distribution patterns, transforming the static LED array into a flexible lighting system.

Inventive Principle:

Principle #15Dynamics

2Illumination intensity

If large numbers of LEDs are used to provide sufficient illumination, then light output is improved, but device complexity and heat management become problematic

Engineering Contradiction:

Improvelight outputVSAvoidsystem complexity

Core Design Contradiction:

Illumination intensityVSDevice complexity

Solution Approach 1:

Instead of using a single large LED array, the system segments the illumination task across multiple smaller LED modules. Each module produces sufficient light for its designated area, and the modular approach simplifies heat management and system maintenance while achieving the required total illumination output.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Heat sinks are introduced as intermediary components between the LED modules and the mounting structure. These heat sinks efficiently transfer and dissipate heat from the LEDs, enabling the use of multiple high-power LEDs without overwhelming thermal management challenges.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 1:

The mounting system incorporates rotational joints and adjustable positioning mechanisms that allow LED modules to be oriented in different directions after installation. This dynamic capability provides adaptability for various lighting scenarios while maintaining relatively simple manufacturing processes.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The LED modules are designed with universal mounting features that accommodate multiple mounting orientations and configurations. The standardized interfaces and adjustable mechanisms allow the same module design to serve multiple functions and adapt to different application requirements.

AI summary

An LED module includes a circular body member for mounting in a lighting assembly or luminaire that can be oriented in an opening in the luminaire by rotating the module about a center axis to a predetermined position to direct the light in a selected pattern. A mounting assembly captures the LED modules between top and bottom mounting members. The LED modules include a heat conducting body coupled to the mounting assembly to conduct heat away from the LED and PCB. A top side of the LED body cooperates with the mounting assembly. A bottom side of the LED body has a cavity supporting a PCB with a plurality of LEDs. A lens body is coupled to the bottom side of the body of the LED module to direct the light to the target area.
