Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional overhead lighting systems are inflexible and costly to install, service, and reconfigure due to their rigid infrastructure, which requires specific positions and types of light fixtures, making modifications such as replacing a linear light with a spotlight or repositioning lights expensive and time-consuming.
Innovation Solution
A modular overhead lighting system featuring a raceway element with exposed conductors allowing variable positioning of interchangeable lighting modules, which can be mechanically and electrically coupled at any position, using an electrical connector with ridges and terminals for secure and adjustable connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional lighting systems use rigid infrastructure with fixed positions, then structural stability is maintained, but adaptability and ease of reconfiguration deteriorate
Solution Approach 1:
The lighting system is segmented into modular components: a raceway infrastructure and interchangeable lighting modules. Each module can be independently installed, removed, and repositioned along the raceway without affecting other modules, enabling flexible reconfiguration while maintaining a simple underlying structure.
Solution Approach 2:
The raceway infrastructure serves as a universal mounting and electrical connection system that can accommodate multiple types of lighting modules (e.g., linear lights, spotlights, pendant lights) at various positions. This multi-functional design allows the same infrastructure to support different lighting configurations without modification.
2Reliability
If each light fixture is independently wired and mounted, then reliability is improved, but installation and servicing time increase
Solution Approach 1:
The system merges mechanical mounting and electrical connection functions into a single integrated interface. The electrical connector simultaneously establishes mechanical attachment to the raceway and electrical connections through its contacts, eliminating separate wiring steps for each fixture while maintaining independent electrical circuits for reliability.
Solution Approach 2:
The modular lighting modules are designed to be self-contained units with pre-integrated electrical connectors. During installation, each module simply needs to be coupled to the raceway, and the electrical connections are automatically established through the connector's contacts, reducing installation complexity and time without compromising circuit integrity.
3Adaptability or versatility
If lighting modules are repositioned or replaced, then adaptability is improved, but electrical connection complexity increases
Solution Approach 1:
The electrical connector acts as an intermediary component between the raceway and lighting modules. It features exposed conductors that interface with corresponding contacts on the module, providing a standardized mediation mechanism that simplifies electrical connections regardless of the specific module type or position, thereby reducing connection complexity while enabling flexible repositioning.

AI summary
A modular overhead lighting system includes a raceway element and one or more interchangeable lighting modules capable of variable positioning relative to the raceway element. Multiple raceway conductors are mounted in the raceway element, with a portion of each raceway conductor being exposed along a lower surface thereof to facilitate continuously variable positioning of lighting modules. An electrical connector for establishing electrical connections between a raceway element and a lighting module includes multiple ridges incorporating electrical contacts configured to contact raceway conductors, and includes terminals to removably receive electrical wires permitting electrical communication between a lighting module and the raceway element.
