Hinge System with Corner and Lockable Hinges
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hinge systems for openings relative to frames lack adaptability to various configurations and do not provide easy locking and unlocking mechanisms, often requiring complex single control systems that are unreliable and difficult to implement across different structures.
Innovation Solution
A hinge system comprising a corner hinge and two lockable/unlockable hinges with separate control members, allowing the opening to pivot around two perpendicular axes, with each hinge having a pivot axis and knuckle configuration that can be locked and unlocked independently using quarter turns or similar control members, facilitating easy adjustment and adaptation to different dimensions and structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single control system is used for multiple hinges, then the device complexity is reduced, but the reliability and ease of operation deteriorate due to insufficient discrimination and control precision
Solution Approach 1:
The control system is segmented into independent control members for each hinge, allowing individual control of each hinge's locking state. This segmentation enables precise and reliable control of each hinge independently, resolving the contradiction between system complexity and control reliability.
Solution Approach 2:
Each hinge is equipped with its own control member with distinct local characteristics, enabling differentiated control for each hinge position. This local quality approach ensures that each hinge can be controlled independently with appropriate discrimination, improving reliability without requiring excessive overall system complexity.
2Reliability
If a hinge system with multiple locking points is used, then the reliability of locking is improved, but the device complexity increases due to additional components
Solution Approach 1:
The hinge system is divided into modular hinge units, each with its own locking mechanism and control member. This segmentation allows multiple locking points to be distributed along the hinge system, improving overall locking reliability while keeping each modular unit relatively simple and manageable.
Solution Approach 2:
The hinge system is pre-configured with multiple locking points at predetermined positions along the hinge axis. This preliminary arrangement of locking points ensures reliable locking capability is built into the system structure itself, reducing the need for additional complex control components during operation.
3Manufacturing precision
If a hinge system designed for specific dimensions is used, then the manufacturing precision is improved, but the adaptability to different configurations deteriorates
Solution Approach 1:
The hinge system incorporates universal mounting features and standardized interface elements that allow the same hinge design to be adapted to various opening dimensions and configurations. This multi-functionality enables the hinge system to maintain manufacturing precision for specific dimensions while being versatile enough for different applications.
Solution Approach 2:
The hinge system includes adjustable and reconfigurable elements that allow dynamic adaptation to different dimensional requirements. These dynamic features enable the hinge system to be configured for specific precision requirements in different applications without sacrificing overall adaptability to various opening sizes and types.

AI summary
Assembly comprising a hinge system mounted on a sash (O) and on a frame (D) and comprising: a) a corner hinge comprising two axes perpendicular to each other, configured to permit the sash to pivot about each of the two axes in turn, b) two lockable/unlockable hinges each comprising a pivot axis and a hinge partially open along its circumference and fully open along its length, the pivot axis being mounted in the hinge parallel to the two corresponding edges of the sash and the frame when the sash is in the closed position relative to the frame, each lockable/unlockable hinge comprising a control member (70, 80) movable between a first position in which the control member is able to lock the pivot axis in the hinge, and a second position in which the control member is able to permit the pivot axis to exit the hinge.
