Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing luminaire assemblies, particularly those with extrusion profiles, face challenges in assembly due to the risk of damaging sensitive components like light sources and require significant workspace, making them difficult to handle and install.
Innovation Solution
A luminaire arrangement with a housing, printed circuit board, light source, supporting elements, biasing elements, and fastening elements, where the biasing elements are inserted perpendicularly between the supporting elements and the housing, and fastening elements are inserted between the biasing elements and the housing, allowing for compact assembly without large forces, thus protecting the light sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If clicking or forging components together for assembly, then assembly strength is improved, but the risk of damaging sensitive components increases
Solution Approach 1:
The patent introduces a damping element positioned between the first component and the second component to absorb assembly forces. This cushioning element prevents direct transmission of high impact forces that would occur during clicking or forging operations, thereby protecting sensitive components like light sources while still enabling secure assembly. The damping element deforms elastically to accommodate assembly tolerances and reduce peak forces.
2Object-affected harmful factors
If sliding components for assembly, then damage risk to components is reduced, but required workspace increases
Solution Approach 1:
The patent employs a nested arrangement where the damping element is positioned within the housing structure, and components are arranged in a compact sequence along the longitudinal axis. The first component, damping element, and second component are nested within each other's spatial envelope, allowing assembly operations to be performed in a confined space without requiring the extended workspace needed for traditional sliding operations.
3Volume of moving object
If making the light fixture compact, then aesthetics and handling are improved, but assembly force requirements increase
Solution Approach 1:
The patent introduces a rotatable component that can rotate about an axis transverse to the longitudinal axis. This dynamic element allows the assembly process to proceed in stages, where the rotatable component first engages in a controlled manner and then locks into position. The rotation mechanism distributes assembly forces over multiple engagement points and time steps, reducing peak force requirements compared to rigid compact designs.
4Reliability
If using extrusion profiles for protective housing, then handling safety is improved, but assembly complexity increases
Solution Approach 1:
The patent designs the housing with integrated features that serve multiple functions: the housing provides protective enclosure, contains mounting surfaces for components, incorporates the damping element positioning, and enables the rotatable assembly mechanism. This multi-functional design eliminates the need for separate protective housings and simplifies the overall assembly process, as a single housing structure performs what would otherwise require multiple separate components.
