Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light fixtures require additional installations for indirect lighting, which are costly and time-consuming, making them unfeasible for many applications.
Innovation Solution
A light fixture design featuring a removable door assembly with integrated LED lighting modules and an optical arrangement, allowing for easy maintenance and replacement, and capable of emitting light both downward and indirectly by incorporating a diffuser, light guide, and reflector.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If additional light fixtures are installed to provide indirect lighting, then the lighting coverage is improved, but the installation cost and time increase
Solution Approach 1:
The patent combines direct and indirect lighting functions into a single light fixture by integrating a downward-facing lighting assembly and a transverse-facing lighting assembly within one housing structure. This merging eliminates the need for separate additional fixtures, thereby maintaining improved lighting coverage while reducing installation time and cost.
Solution Approach 2:
The light fixture is designed with multi-functionality to provide both direct downward lighting and indirect transverse lighting through a single device. The housing contains multiple lighting assemblies with different orientations, allowing one fixture to perform multiple lighting functions that would traditionally require separate fixtures, thus reducing installation complexity and time.
2Illumination intensity
If additional light fixtures are installed to provide indirect lighting, then the lighting coverage is improved, but the installation cost increases
Solution Approach 1:
The patent merges multiple lighting functions into a single integrated fixture, combining direct and indirect lighting assemblies within one housing. This reduces the total number of fixtures needed, simplifying installation procedures and reducing overall installation cost while maintaining comprehensive lighting coverage.
Solution Approach 2:
By designing a universal light fixture that performs both direct and indirect lighting functions, the patent reduces device complexity in terms of installation quantity and coordination. A single multi-functional fixture replaces what would traditionally require multiple specialized fixtures, thereby reducing installation complexity and associated costs.
3Stability of the object's composition
If the lighting assembly is permanently installed in the housing, then the structural stability is improved, but the maintenance accessibility deteriorates
Solution Approach 1:
The patent segments the lighting assembly from the housing by providing a removable access panel or door on the housing. This allows the lighting assembly to be permanently installed within the housing for structural stability, while enabling easy removal and replacement through the access panel, thereby maintaining ease of repair without compromising structural integrity.
4Reliability
If the door assembly is permanently attached to the housing, then the seal integrity is improved, but the component replacement accessibility deteriorates
Solution Approach 1:
The door assembly is segmented from the main housing structure through a removable connection mechanism. This allows the door to be permanently attached when closed for seal integrity, while enabling easy removal when opened for maintenance access. The segmentation principle resolves the contradiction by allowing the door to switch between sealed and accessible states.
Solution Approach 2:
The door assembly incorporates dynamic characteristics by being designed for removable attachment rather than permanent fixation. This dynamic design allows the door to transition between attached (providing seal integrity) and detached (providing access) states, resolving the contradiction between reliability and ease of repair.

AI summary
A light fixture includes a housing, a door assembly, and a lighting assembly. The housing can have a top wall, sidewalls, and a bottom opening. The housing can further define a plenum chamber between the top wall, the sidewalls, and the bottom opening. The door assembly can be removably attached to the housing adjacent the bottom opening. The lighting assembly can include at least one lighting module carried by the door assembly inside of the plenum chamber such that when the door assembly is detached from the housing, the lighting assembly can be at least partially removed from the plenum chamber. The door assembly can include a door frame and an optical arrangement carried by the door frame. The optical arrangement can be configured to allow light generated by the lighting assembly to be emitted from the light fixture.
