Hinge Electrical Line Routing and Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional door hinges with integrated electrical connections face issues with varying line lengths due to the distance between the hinge axis and the routing point, leading to unnecessary length changes during opening and closing, which complicates the provision of a stable and tamper-proof electrical connection.
Innovation Solution
The routing point is positioned closer to the hinge axis, with a ratio of distance to line section length less than 1:3, allowing the electrical line to be routed efficiently without significant length changes, and incorporating a groove within the hinge bracket for concealed and protected line placement, along with a detachable connection for ease of installation and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the routing point is positioned far from the hinge axis, then the electrical line can be routed to the wall section of the second fastening device, but the line length changes significantly during opening and closing movements
Solution Approach 1:
The patent pre-calculates and optimizes the routing point position before the hinge is assembled and installed. By determining the optimal routing point location in advance (during the design phase rather than during operation), the electrical line length is minimized and stabilized, reducing the need for excessive line reserves while ensuring proper routing to the wall section of the second fastening device
2Ease of manufacture
If the electrical line is routed externally on the hinge bracket, then installation and maintenance are simplified, but the connection becomes vulnerable to tampering and damage
Solution Approach 1:
The patent implements a nested structure where the electrical line is concealed within a housing or cover that forms part of the hinge bracket assembly. The electrical line is routed through internal channels or grooves within the hinge bracket, and the housing protects it from external access. This nested arrangement maintains ease of installation during manufacturing while providing security against tampering and damage during use
3Reliability
If the electrical line is routed within the hinge bracket, then the connection is protected and concealed, but the line length must be longer to accommodate the internal routing path
Solution Approach 1:
The patent utilizes three-dimensional internal channels and grooves within the hinge bracket to route the electrical line. By exploiting the vertical and depth dimensions of the hinge bracket structure rather than simple linear paths, the electrical line can be concealed and protected while minimizing the actual length of cable required. The routing follows the contours of internal cavities and passages designed into the hinge bracket
