Hinge Bracket With Orthogonal Bearing Bore For Frame Profile Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door hinges cannot be used when no side element of the cabinet body is formed next to the door, and they require significant effort to attach to a frame profile, limiting their usability and installation efficiency.
Innovation Solution
The design allows for easy attachment of bearing blocks to a frame profile with an engagement section that aligns orthogonally to the groove channel, enabling the door to be pivoted above a frame profile without side elements, using a hinge bracket with a bearing bore parallel to the groove channel's longitudinal direction and another transverse to it, ensuring stable alignment and guidance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional hinge is used requiring side elements of the cabinet body, then the door can be pivoted about a vertical axis, but the hinge cannot be used when no side element is formed next to the door
Solution Approach 1:
The invention changes the orientation of the bearing bore from the conventional horizontal alignment to a vertical orientation. The bearing block is designed with a bearing bore that extends in the longitudinal direction of the frame profile, allowing the door to pivot about a horizontal axis rather than a vertical axis. This dimensional change enables the hinge to function in cabinet configurations where no side elements are present, as the rotation occurs along the length of the frame profile rather than requiring lateral support.
2Ease of manufacture
If hinge brackets are attached to a frame profile, then the door can be mounted on the cabinet body, but the attachment requires great effort
Solution Approach 1:
The hinge bracket is segmented into distinct functional areas: a fastening area with a fastening bore for attachment to the frame profile, and a bearing area with the bearing bore for receiving the hinge pin. This segmentation allows the fastening area to be independently optimized for easy attachment using standard fastening methods, while the bearing area handles the rotational function. The clear separation of functions simplifies the attachment process and reduces installation time.
Solution Approach 2:
The bearing block acts as an intermediary element that connects the door to the frame profile. It provides a standardized interface with a bearing bore that receives the hinge pin, and a fastening area that interfaces with the frame profile. This intermediary component simplifies the overall attachment process by providing pre-configured mounting features that require minimal additional effort during installation.
3Adaptability or versatility
If the bearing bore is aligned orthogonally to the groove channel, then the door can be mounted in an area with only top and bottom frame profiles, but the hinge bracket requires specific orientation
Solution Approach 1:
The hinge bracket exhibits local quality through its asymmetric design: the bearing bore is oriented perpendicular to the frame profile's longitudinal axis, while the fastening area is positioned to engage with the frame profile in a specific orientation. This localized differentiation in orientation and function allows the hinge to be mounted in unique locations (such as top and bottom frame profiles only) while maintaining proper alignment through the designed geometric relationship between the bearing bore and fastening area.
