Hinge Cup Partially Protruding Frame Profile
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in designing hinges for frame profiles that accommodate surface elements like glass panes is the difficulty in connecting the frame profile and the hinge stop part due to limited space and material thickness, leading to complex and costly special hinge shapes.
Innovation Solution
A hinge design where the hinge cup is partially received in a recess of the frame profile and partially protrudes laterally, allowing for tool-free assembly and disassembly using a traction strap and clamping element, enabling the use of narrower, less expensive frame profiles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the hinge cup is completely sunk into the frame profile, then the connection is stable and reliable, but the frame profile must be wide and expensive
Solution Approach 1:
The hinge cup is partially nested into the frame profile recess, with the remaining portion extending outward. This partial nesting approach provides sufficient connection stability while reducing the required frame profile width compared to complete nesting, thereby resolving the contradiction between connection reliability and frame width.
Solution Approach 2:
The solution moves from a two-dimensional planar connection (complete sinking into the profile face) to a three-dimensional partial protrusion connection. By allowing the hinge cup to extend in the lateral dimension beyond the profile face, the connection maintains reliability without requiring increased profile width in the transverse dimension.
2Reliability
If complex special shape hinges are used, then reliable attachment to narrow frame profiles is achieved, but production and purchase costs increase
Solution Approach 1:
The hinge system is segmented into standardized components: a conventional circular hinge cup, a simple cylindrical recess in the frame profile, and a separate traction strap assembly. This segmentation allows each component to be manufactured using standard processes without requiring complex special shapes, reducing production costs while maintaining attachment reliability.
Solution Approach 2:
The hinge cup is designed as a universal standard component that can be produced by conventional methods, replacing the need for custom-molded special shape hinges. This universal component works effectively with the simple recess geometry, enabling reliable attachment to narrow frame profiles through standardized, cost-effective manufacturing.
3Length of moving object
If narrow frame profiles are used, then visual appeal and cost are improved, but the hinge cup cannot be fully accommodated
Solution Approach 1:
The hinge cup is partially nested into the narrow frame profile recess, with the nesting depth optimized to provide sufficient structural support and connection reliability within the constrained width. The partial nesting approach allows the hinge cup to be adequately accommodated without requiring the full width that would be needed for complete nesting.
Solution Approach 2:
The solution compensates for the limited width in the transverse dimension by utilizing the lateral dimension, allowing the hinge cup to extend beyond the profile face. This dimensional transition ensures adequate accommodation and connection reliability even when the frame profile width is reduced for aesthetic and cost reasons.
4Ease of operation
If tool-free assembly is implemented, then ease of installation is improved, but assembly mechanism complexity increases
Solution Approach 1:
The traction strap assembly functions as a self-service mechanism where the installer directly manipulates the strap to tension and secure the hinge cup in the recess. The system uses the installer's own manual force applied through the strap, eliminating the need for external assembly tools while keeping the mechanism relatively simple through direct mechanical engagement.
Solution Approach 2:
The traction strap utilizes a flexible belt or film structure that can be tensioned and locked into place to secure the hinge cup. This flexible element provides a simple yet effective tool-free assembly mechanism, allowing the hinge cup to be firmly attached through the friction and tension of the strap without requiring complex locking devices or specialized tools.
