Solution Overview
Problem
Existing emergency lighting devices for confined spaces, such as recessed luminaires, face challenges in manufacturing and mounting complexity due to extensive cabling and cumbersome handling of multiple flexible parts, which complicates installation and access to small spaces.
Innovation Solution
A lighting device with a first housing containing electronic circuitry and a second housing with energy storage, connected via an interconnecting means that provides both elastic mechanical and electrical connections, featuring a hinge-like structure with pre-bended portions to facilitate insertion and mounting in tight spaces, allowing for thermal isolation and easy handling as a single unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If extensive cabling and multiple flexible parts are used to connect battery and electronic circuitry in confined spaces, then the lighting device can function in emergency mode, but manufacturing and mounting complexity increases
Solution Approach 1:
The patent combines the mechanical connection and electrical connection functions into a single integrated interconnecting means. The connector assembly includes both mechanical attachment features and electrical contacts within one component, eliminating the need for separate cabling and reducing the number of parts that need to be handled during installation.
Solution Approach 2:
The interconnecting means serves multiple functions simultaneously: it provides mechanical support, enables electrical connection, and allows for pivotal movement. This multi-functional design reduces the overall complexity of the system by consolidating multiple requirements into a single component.
2Volume of moving object
If multiple separately connected functional units are used to fit in confined spaces, then the lighting device can be installed in tight spaces, but handling and assembly becomes cumbersome
Solution Approach 1:
The electronic circuitry and energy storage means are connected through an integrated interconnecting means that acts as a single handling unit. This allows the installer to manipulate the connection as one piece rather than dealing with multiple separate cables and connectors, significantly improving ease of operation during installation.
3Volume of moving object
If electronic circuitry and energy storage are placed close together to reduce space, then the lighting device fits in confined spaces, but thermal isolation is compromised
Solution Approach 1:
The patent extracts the energy storage means into a separate housing from the electronic circuitry. This physical separation removes the heat-generating electronic components from proximity to the temperature-sensitive battery, providing thermal isolation while still allowing the device to fit in confined spaces due to the compact interconnecting means.
4Stability of the object's composition
If rigid connections are used between housings to ensure structural stability, then the lighting device maintains structural integrity, but installation in tight spaces becomes difficult
Solution Approach 1:
The interconnecting means incorporates pivotal capability that allows it to change its angular position during installation. This dynamic feature enables the connector to navigate tight spaces and awkward angles while still providing stable structural connection once installed, combining adaptability with structural integrity.
