Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional buried lighting apparatuses have a separate junction box that increases their size and complexity, making them cumbersome to handle and install, and require multiple trim sizes for varying design specifications and construction situations, leading to inefficiencies in construction work.
Innovation Solution
An integrated slim-type LED lighting apparatus with a junction box that serves as a heat sink, allowing for size reduction and easy installation, and interchangeable trims of different diameters coupled using spring clips, facilitating field adjustments based on design or construction needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a separate junction box is installed outside the lighting apparatus, then wiring and cable management are facilitated, but the overall size and complexity of the lighting apparatus increase
Solution Approach 1:
The patent integrates the junction box directly into the lighting apparatus housing, combining two previously separate components (junction box and lighting apparatus) into a single unified structure. This eliminates the need for a separate external junction box while maintaining all necessary wiring and cable management functions within the apparatus itself.
Solution Approach 2:
The lighting apparatus housing is designed to serve multiple functions simultaneously: it provides structural support, housing for electrical components, and an integrated junction box for cable management. This multi-functionality reduces the need for additional separate components and simplifies the overall system.
2Adaptability or versatility
If multiple trim sizes are provided for different design specifications, then adaptability to various construction situations is improved, but device complexity and inventory requirements increase
Solution Approach 1:
The trim is designed as a separate, interchangeable component that can be detached and replaced independently from the main lighting apparatus. This segmentation allows different trim sizes to be used with the same apparatus body, reducing the need for multiple complete apparatus variants.
Solution Approach 2:
The trim is designed to be dynamically interchangeable through a simple attachment mechanism, allowing the configuration to be changed based on installation requirements. This dynamic adaptability replaces the need for multiple static apparatus variants.
3Volume of stationary object
If the junction box is integrated with the LED module, then size reduction and slimming are achieved, but heat dissipation requirements become more critical
Solution Approach 1:
The junction box is merged with the LED module assembly, creating an integrated unit that reduces overall size. This integration allows the housing to serve as a unified structure that accommodates both electrical connections and LED components in close proximity.
Solution Approach 2:
The housing structure is designed to perform multiple functions: it provides mechanical support, electrical connectivity through the integrated junction box, and thermal management for the LED module. This multi-functionality allows compact design while addressing heat dissipation requirements.
