Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for energy-efficient light fixtures that utilize LED lights, particularly in sensitive environments like MRI rooms, where traditional light sources are not suitable.
Innovation Solution
A light fixture design featuring a frame with vertically oriented LED strips, a glass light guide plate, a diffused lens panel, a reflective sheet, and a metal backing, which allows the LED strips to be hidden from view and minimizes ferromagnetic interference, while using a foam layer and T-Bar hangers for installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If traditional light sources are used, then illumination is provided, but energy efficiency is poor and they are not suitable for MRI rooms
Solution Approach 1:
The patent changes the light source parameter from traditional bulbs to LED strips, which fundamentally alters energy consumption characteristics. LEDs consume significantly less energy and produce minimal heat, making them suitable for MRI room environments where heat generation and energy efficiency are critical concerns.
Solution Approach 2:
The patent employs LED strips that are modular and replaceable. These LED components have long operational lifespans compared to traditional sources, reducing maintenance frequency and cost, while their modular design allows for easy replacement if failure occurs, ensuring continuous operation in critical MRI environments.
2Use of energy by moving object
If LED strips are placed horizontally, then energy efficiency is improved, but the light sources become visible from outside
Solution Approach 1:
The patent transitions the LED strip orientation from horizontal to vertical placement. This dimensional change in arrangement allows the light-emitting components to be positioned within recessed vertical portions of the frame structure, hiding them from external view while maintaining their energy-efficient lighting function.
Solution Approach 2:
The LED strips are nested within recessed vertical portions of the frame. This nesting arrangement conceals the light sources inside the frame structure, making them invisible from outside the fixture, while still allowing the light to diffuse evenly through the transparent panel.
3Strength
If metal backing is used, then structural support is provided, but ferromagnetic interference occurs in MRI rooms
Solution Approach 1:
The patent changes the material parameter of the backing from ferromagnetic metal to non-ferromagnetic materials such as aluminum or plastic. This material substitution maintains the structural support function while eliminating ferromagnetic interference, making the fixture safe for use in MRI room environments where magnetic field sensitivity is critical.
4Object-generated harmful factors
If LED strips are placed in vertical portions further inside the frame, then light sources are hidden, but installation complexity increases
Solution Approach 1:
The patent segments the frame into distinct portions, including recessed vertical areas specifically designed to house the LED strips. This segmentation creates pre-defined installation zones that simplify the manufacturing process and make it easier to install LED strips in concealed positions without requiring complex custom fabrication.
