Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current emergency lighting devices are complex to install and require external junction boxes for electrical connections, which complicates the installation process and can lead to unnecessary complexity and potential errors in series connections.
Innovation Solution
A tubular emergency lighting device with semi-cylindrical shells containing light-emitting diodes and a transparent casing, featuring end pieces with cable orifices for direct electrical connection and 'L'-shaped flanges to secure visual signaling elements, simplifying installation and eliminating the need for external junction boxes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If external junction boxes are used for electrical connections, then connection reliability is improved, but device complexity increases and installation becomes more difficult
Solution Approach 1:
The patent integrates the electrical connection function directly into the end caps of the housing. The first end cap contains a first electrical connection for the first lighting means, and the second end cap contains a second electrical connection for the second lighting means. This merging of connection functions into existing structural components eliminates the need for separate external junction boxes, thereby reducing device complexity while maintaining connection reliability.
2Adaptability or versatility
If multiple lighting means are installed in opposite directions, then versatility is improved, but device complexity increases
Solution Approach 1:
The patent designs the housing with universal end caps that can each accommodate lighting means oriented in different directions. The first end cap houses first lighting means oriented in a first direction, while the second end cap houses second lighting means oriented in a second direction opposite to the first direction. This universal design allows the same housing structure to support multiple lighting configurations without increasing complexity, as each end cap is independently designed to handle its own lighting means.
3Ease of operation
If end caps are designed with integrated electrical connections, then ease of installation is improved, but manufacturing precision requirements increase
Solution Approach 1:
The electrical connections are merged into the end cap structures themselves. The first end cap includes a first electrical connection configured to connect to the first lighting means, and the second end cap includes a second electrical connection configured to connect to the second lighting means. This integration simplifies installation by eliminating separate connection components, while the manufacturing precision is managed through standardized end cap designs that can be produced with consistent tolerances.
