Rotatable Security Camera Cable Management via Slip Ring and Wire Guide
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Movable type security cameras require an improved coupling structure for cables connecting fixed and movable circuit boards to ensure secure and uninterrupted connectivity during camera rotation, as existing solutions are prone to entanglement and interference.
Innovation Solution
A coupling cable system featuring a slip ring and wire guide with a fixing section and ferrite core to support the cable, preventing entanglement and maintaining connectivity during camera rotation, while a slip ring supports the cable rotation and a wire guide fixes it to the top plate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a coupling cable connects fixed and movable circuit boards in a rotatable camera system, then electrical connectivity is maintained during rotation, but the cable becomes entangled and interfered with by the rotating motion
Solution Approach 1:
A wire guide is introduced as an intermediary component between the coupling cable and the rotating camera body. The wire guide includes a fixing section that secures the cable to the top plate, preventing the cable from becoming entangled during rotation while maintaining electrical connectivity between the fixed and movable circuit boards.
2Ease of operation
If the coupling cable is allowed to move freely during rotation, then rotation smoothness is improved, but cable entanglement and interference occur
Solution Approach 1:
The cable management system is segmented into distinct functional sections: a wire drawing section that guides the cable through the top plate, a fixing section that secures the cable to prevent entanglement, and a connector section that maintains electrical connectivity. This segmentation allows the cable to be properly routed and secured without interfering with rotation.
3Strength
If the wire guide fixing section is formed perpendicular to the wire guide, then cable fixation strength is improved, but device complexity increases
Solution Approach 1:
The fixing section is merged with the wire guide structure, forming an integrated component rather than a separate attachment. The fixing section is formed substantially perpendicularly to the wire guide body, creating a unified structure that provides strong cable fixation without requiring additional separate components or complex assembly steps.

AI summary
The disclosed security camera includes a case body mounted on a fixed wall. A top plate is rotatably installed at one side of the case body. A movable circuit board is installed at one side of the top plate. A fixed circuit board is fixed in the case body. A camera unit is installed at the other side of the top plate. A coupling cable connects the movable circuit board and the fixed circuit board. A slip ring supports the coupling cable without being influenced by rotation of the top plate. A wire guide substantially prevents movement of the coupling cable drawn from an upper side of the top plate. A wire guide includes a wire drawing section through which the coupling cable passes. Fixing ribs are provided at one side of the wire guide to fix the coupling cable drawn through the wire drawing section to the upper surface of the top plate. The fixing ribs are installed at a certain interval to fix a core inserted around the coupling cable.
