Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door hinges with concealed electrical connections are complex to assemble and prone to cable damage during door operation, posing a risk to connected devices like electric locks and alarm systems.
Innovation Solution
A door hinge design featuring pre-assembled flexible electrical connection elements with plugs or sockets at both ends, secured to receiving bodies via a multi-core ribbon cable and holding elements, simplifying assembly and reducing cable damage risk through secure fixation and protected routing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a ribbon cable is passed through between the hinge brackets and emerges from the receiving bodies, then the electrical connection is established, but the cable can be damaged by uncontrolled movements during door actuation
Solution Approach 1:
The electrical connection element is nested within the hinge structure, specifically integrated into the receiving bodies. The contact elements are fixed to the receiving bodies, and the multi-core cable is routed through the hinge arrangement in a protected manner, shielding it from external damage during door actuation.
Solution Approach 2:
The electrical connection element is pre-assembled with contact elements at both ends connected by a multi-core cable before installation. This pre-assembly allows the connection element to be ready for immediate use, eliminating the need for on-site cable routing and connection, and ensures proper positioning that protects the cable from damage.
2Reliability
If individual wires of the cable are connected during assembly and installation, then the electrical connection is established, but the assembly process becomes complex
Solution Approach 1:
Multiple individual wire connections are merged into a single pre-assembled electrical connection element. The contact elements at both ends of the multi-core cable are pre-connected and fixed to the receiving bodies, transforming a complex multi-step wiring process into a single integration step during assembly.
Solution Approach 2:
The electrical connection element is pre-assembled with all necessary wire connections established before the final installation. This preliminary preparation of the electrical connections eliminates the need for complex on-site wiring work, simplifying the assembly process while ensuring reliable electrical connectivity.
3Ease of operation
If the cable is routed through the hinge arrangement, then electrical connection is achieved, but the cable is exposed to mechanical stress and uncontrolled movements
Solution Approach 1:
The multi-core cable is nested within the protected space of the hinge arrangement, specifically routed through the receiving bodies in a manner that shields it from external mechanical stress and uncontrolled movements during door actuation.
Solution Approach 2:
The cable routing path is predetermined and prepared in advance during the design and pre-assembly phase. The electrical connection element is pre-positioned within the hinge structure, ensuring the cable follows a protected path that minimizes exposure to mechanical stress during operation.
