Hinge Hydraulic Damping Partial Pivot Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hinges with hydraulic damping devices do not effectively limit damping to a partial pivoting angle, allowing excessive movement and energy dissipation during the entire pivoting range.
Innovation Solution
Incorporating a guide slot section normal to the pivot axis and utilizing two guide links oriented oppositely, along with a second damping device in the first leg, to interact with the guide link of the second guide part, thereby limiting damping to a specific partial pivot angle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hydraulic damping device acts during entire pivoting movement, then damping is continuous, but energy dissipation is excessive and damping cannot be limited to partial pivot angle
Solution Approach 1:
The guide slot is divided into multiple sections with different orientations: a first section oriented at an angle to the pivot axis that enables damping action, and a second section arranged normal to the pivot axis that limits damping to a partial pivot angle. This segmentation allows the damping device to operate only in specific angular ranges, preventing excessive energy dissipation while maintaining reliable damping control where needed.
Solution Approach 2:
Instead of providing damping throughout the entire pivoting range, the invention applies damping partially - only in specific angular sections defined by the guide slot orientation. The guide slot's angled section provides damping during controlled portions of the pivoting movement, while the normal section restricts further damping action, achieving energy efficiency without sacrificing necessary damping control.
2Loss of energy
If guide slot is arranged normal to pivot axis to limit damping, then energy dissipation is reduced, but damping control during full pivoting range is lost
Solution Approach 1:
The guide slot is segmented into functional sections: an angled section that provides damping control during specific pivoting phases, and a normal section that limits damping to partial angles. This segmentation ensures energy efficiency is achieved without completely sacrificing damping control, as the angled section maintains precise damping where required.
Solution Approach 2:
Different sections of the guide slot have different functional qualities - the angled section provides active damping control with precise force regulation, while the normal section provides passive geometric limitation. This local differentiation of quality allows the system to be energy-efficient overall while maintaining high damping control precision in critical local regions.
3Device complexity
If single damping device is used, then device complexity is low, but damping cannot be precisely controlled over different pivoting angles
Solution Approach 1:
While maintaining a relatively simple overall structure with essential damping components, the guide slot is segmented into multiple oriented sections that work together with the single damping device. This geometric segmentation compensates for the simplicity of having one damping device, enabling precise damping control over different pivoting angles through the clever design of the guide slot's angular sections.

AI summary
The invention relates to a hinge, comprising two legs, which can be swiveled relative to each other about a swivel axis between an initial position and an end position, and a hydraulic damping device, which is arranged on one of the legs and which comprises an actuation part that can be slid parallel to the swivel axis. For this purpose, the actuation part can be loaded by means of a guide part of a linear guiding system. The other leg comprises a second guide part of the linear guiding system. At least one of said guide parts has a slotted guide for guiding the other guide part. In addition, the slotted guide has at least one section that is arranged perpendicularly to the swivel axis of the hinge. According to the present invention, a hinge is developed, the damping of which is limited to a partial swivel angle.
