Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If conventional LED lighting fixtures use a single linear array of LEDs in a hollow tube, then the structure is simple and easy to manufacture, but the light distribution is uneven and produces hot spots
Solution Approach 1:
The patent transitions from a single linear array of LEDs in one dimension to multiple LED arrays arranged in three-dimensional space, with LEDs positioned at different heights and angles to achieve uniform light distribution across the display case interior
Solution Approach 2:
The fixture is divided into multiple independent LED arrays mounted on separate support members, allowing each array to be positioned and angled independently to optimize light distribution and eliminate hot spots
2Ease of operation
If conventional LED fixtures use cumbersome housing configurations, then the structural integrity is maintained, but installation becomes difficult and custom applications are hindered
Solution Approach 1:
The fixture is segmented into modular components including separate support members, LED arrays, and mounting brackets, allowing easy assembly and adaptation to different display case configurations and custom applications
Solution Approach 2:
The mounting system incorporates adjustable and removable elements that allow the fixture to be dynamically configured for different installation scenarios, enhancing both ease of installation and adaptability to custom applications
3Use of energy by moving object
If conventional LED fixtures do not integrate thermal management, then the design is simpler, but energy consumption increases and component life is reduced
Solution Approach 1:
The thermal management function is merged with the structural support members, which are made of thermally conductive materials that simultaneously provide mechanical support and heat dissipation pathways for the LED arrays
Solution Approach 2:
The support members serve multiple functions: providing structural support for the LED arrays, conducting heat away from the LEDs, and acting as mounting surfaces for the optical components, thereby reducing overall system complexity while improving thermal management

AI summary
An LED light fixture assembly includes an elongated first support member, an elongated second support member spaced from and substantially parallel to the first support member, and a plurality of elongated LED lighting fixtures coupled to and extending between the first support member and the second support member. Each LED lighting fixture includes an elongated structural frame member having a substantially channel shaped support portion, and a mounting portion opposite the support portion. Each LED lighting fixture also includes a plurality of LED light modules secured to and positioned along the mounting portion, and a cover extending along and supported by the mounting portion. The cover is positioned so light emitted from the plurality of LED light modules passes through the cover and away from the mounting portion.
