Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional track lighting systems suffer from complex installation procedures and the creation of invalid dark areas due to electrical wire arrangements and opaque end caps, leading to uneven brightness and reduced illumination when multiple fixtures are connected in a line.
Innovation Solution
The introduction of a track light system featuring a hollow track shell with power supply components and a mating connection rail, along with light guide end caps on each lighting fixture to eliminate dark areas and facilitate direct electrical connection, allowing for seamless installation and enhanced brightness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If multiple lighting fixtures are connected by electrical wires and sockets, then the lighting fixtures can be mounted on ceiling or wall surface, but the arrangement of electrical wires and opaque end caps causes invalid dark areas between fixtures, resulting in uneven brightness and reduced illumination
Solution Approach 1:
The patent merges the electrical connection function into the track structure itself. The track contains embedded power supply components and mating connection rails that directly provide electrical connection to multiple lighting fixtures, eliminating the need for separate electrical wires and sockets between fixtures. This integration resolves the contradiction by simplifying the device structure while maintaining illumination uniformity through the elimination of dark areas caused by wire arrangements.
Solution Approach 2:
The patent extracts the electrical connection components (wires and sockets) from the space between lighting fixtures. By removing these obstructive elements and replacing them with a track-based power supply system, the invalid dark areas are eliminated, achieving uniform brightness across all fixtures without the complexity of wire management.
2Area of stationary object
If multiple lighting fixtures are connected in a string, then a long bright illumination area can be produced, but the mounting procedure becomes complicated and inconvenient
Solution Approach 1:
The patent combines the mounting and electrical connection functions into a single track-based system. The track shell with embedded power supply components and mating connection rails allows lighting fixtures to be mounted and electrically connected simultaneously through a plug-and-play interface, greatly simplifying installation while enabling the creation of long illumination areas by arranging multiple fixtures along the track.
Solution Approach 2:
The patent segments the lighting system into modular components: a track structure with power supply components and multiple detachable lighting fixtures. Each fixture can be independently installed or removed by plugging into the track, making the installation process simple and convenient while allowing flexible configuration to achieve desired illumination areas.
3Reliability
If opaque end caps are used on lighting fixtures, then the fixtures can be sealed, but dark areas are generated between adjacent fixtures, reducing overall illumination
Solution Approach 1:
The patent applies local quality by making the end caps transparent or translucent rather than opaque. This allows light to pass through the end caps of adjacent fixtures, eliminating the dark areas that would otherwise be created between fixtures. The sealing function is maintained while the optical property is changed to improve overall illumination and brightness uniformity.
