Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric lights for building installations often require complex cable connections for coupling to electrical systems, which can be cumbersome and limit ease of alignment and installation.
Innovation Solution
The electric light design features a hat-shaped coupling part that fits into a cylindrical pot-shaped recess on an attachment device, allowing for mechanical, electrical, and data-technical coupling without cables, with sliding contacts for secure and adjustable alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cable connections are used for coupling electric lights to electrical systems, then reliable electrical connection is achieved, but installation complexity and ease of alignment are worsened
Solution Approach 1:
The patent combines mechanical coupling, electrical connection, and alignment functions into a single integrated hat-shaped coupling part. The coupling part incorporates sliding contacts for electrical connection and geometric features for alignment, eliminating the need for separate cable connections and simplifying installation while maintaining reliable electrical contact.
Solution Approach 2:
The hat-shaped coupling part serves multiple functions simultaneously: it provides mechanical attachment to the pot-shaped recess, establishes electrical connections through integrated sliding contacts, and enables precise alignment through its geometric configuration. This multi-functional design replaces traditional separate components for each function.
2Reliability
If complex cable connections are used, then reliable electrical connection is achieved, but ease of operation during installation is worsened
Solution Approach 1:
The coupling part merges electrical contacts with mechanical coupling features, so that a single insertion action simultaneously establishes both mechanical attachment and electrical connection. This eliminates the need for separate cable handling and connection steps, greatly improving ease of operation.
Solution Approach 2:
The sliding contacts are pre-positioned within the hat-shaped coupling part, and the geometric features are pre-configured to guide alignment. When the coupling part is inserted into the pot-shaped recess, the preliminary positioning features automatically guide the components into proper alignment before final engagement, reducing manual adjustment during installation.
3Reliability
If traditional coupling methods are used, then secure connection is achieved, but device complexity is increased
Solution Approach 1:
The hat-shaped coupling part is designed as a universal interface that simultaneously handles mechanical attachment, electrical connection, and alignment functions. This single component replaces what would traditionally require multiple separate components (mechanical fasteners, cable connectors, alignment features), reducing overall device complexity while maintaining secure connection.
