Pivot Window Hinge Electrical Connection Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pivot window hinge systems with electrical connections between the sash and frame face challenges in maintaining flexibility during operation, assembly, and installation, particularly in ensuring secure and hidden electrical contacts that do not interfere with the window's rotation for cleaning purposes.
Innovation Solution
The integration of electrical socket parts within the hinge mechanism, where one socket part is guided in a circular track following the curvature of the guide member, providing a secure and automatic electrical connection between the sash and frame, with socket parts positioned on the hinge parts for protection and ease of assembly, allowing for a wider range of sash movement while minimizing wire exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If visible electrical contacts are provided on the surfaces of the sash and frame members (as in prior art), then electrical power can be supplied to screening arrangements, but the electrical connection becomes visible and affects the aesthetic appearance and flexibility of the window
Solution Approach 1:
The electrical contact function is extracted from the visible surface area of the sash and frame members and relocated to the hinge mechanism. The socket parts are integrated into the hinge parts, specifically positioned on the guide member and slide member, so that the electrical connection is established through the hinge connection rather than through visible contacts on the window surfaces. This extraction resolves the contradiction by maintaining electrical reliability while eliminating visual impact and preserving window flexibility.
Solution Approach 2:
The electrical socket parts are nested within the hinge mechanism structure. The first socket part is integrated into the guide member of the first hinge part, and the second socket part is integrated into the slide member of the second hinge part. This nesting allows the electrical connection to be housed within the existing hinge components, maintaining reliability while keeping the connection hidden and non-intrusive to the window's operational flexibility and aesthetics.
2Reliability
If wires are led from the frame into protective chain elements to provide electrical connection (as in prior art), then electrical power can be supplied, but the wires are exposed to pinching risks and complicate the assembly process
Solution Approach 1:
The wire protection function is extracted from the chain element and integrated directly into the hinge mechanism. The electrical socket parts are positioned on the guide member and slide member of the hinge, eliminating the need for separate protective chain elements and exposed wires. This extraction simplifies the device by combining the electrical connection function with the existing hinge structure, reducing assembly complexity while maintaining reliable power supply.
Solution Approach 2:
The electrical connection function is merged with the hinge mechanism. The socket parts are integrated into the hinge parts, and the electrical connection is established through the interaction between the guide member and slide member during the pivoting motion. This merging eliminates the need for separate wire protection systems and simplifies the overall device structure, reducing assembly complexity while ensuring reliable electrical contact throughout the window's range of motion.
3Ease of operation
If electrical socket parts are integrated into the hinge mechanism with one socket guided in a circular track, then the electrical connection becomes hidden and automatic, but the hinge structure becomes more complex
Solution Approach 1:
The hinge mechanism is given multi-functionality by integrating the electrical connection function into its structure. The guide member and slide member of the hinge not only provide the mechanical pivoting function but also house the electrical socket parts that establish electrical contact. This multi-functionality allows the hinge to simultaneously perform mechanical support and electrical connection, achieving automatic hidden electrical connection while minimizing additional complexity by utilizing existing hinge components.
Solution Approach 2:
The first socket part is guided in a circular track on the guide member, matching the curvature of the pivoting motion. This curved guidance path ensures that the electrical contact between the socket parts is maintained throughout the window's range of motion. The circular track design naturally follows the arc of the hinge rotation, providing automatic electrical connection while integrating smoothly into the hinge structure without requiring complex additional components.
