Hinge Covering Element with Positioning Projections for Extended Adjustment Range
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hinge arrangements in door and window joinery have a limited range of adjustment due to a narrow gap between the hinge member and the frame, which restricts the positioning of the hinge member relative to the frame assembly, and this is aesthetically and operationally suboptimal.
Innovation Solution
A covering element with a specific design featuring L-shaped or C-shaped cross-sections, including central and side arms, and positioning projections that extend from the central arm, allowing for increased adjustment range without enlarging the gap, and providing protection against damage and unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the gap width between the hinge member and the frame is kept narrow for aesthetic and security reasons, then the aesthetic appeal and security are improved, but the adjustment range of the hinge member is limited
Solution Approach 1:
The covering element extends in the longitudinal direction of the frame element, utilizing the third dimension (length along the frame) to provide adjustment capability without increasing the transverse gap width. This allows the hinge member to be positioned at multiple locations along the longitudinal axis while maintaining a narrow gap for aesthetic purposes.
Solution Approach 2:
The covering element acts as an intermediary structure that bridges the gap between the hinge member and the frame. It provides positioning projections that engage with corresponding features on the hinge member, enabling adjustment while maintaining the narrow gap appearance from the exterior.
2Reliability
If the gap width between the hinge member and the frame is kept narrow for security reasons to prevent unauthorized access, then security is improved, but the adjustment range of the hinge member is limited
Solution Approach 1:
The covering element utilizes the longitudinal dimension of the frame element to provide multiple positioning options for the hinge member. By extending along the length of the frame element with positioning projections, it enables adjustment range in the longitudinal direction while maintaining a narrow transverse gap width for security purposes.
Solution Approach 2:
The covering element is divided into multiple sections along its longitudinal axis, with positioning projections at different locations. This segmentation allows the hinge member to be positioned at multiple discrete locations along the frame element, providing adjustment capability without requiring a wider gap.
3Adaptability or versatility
If the covering element is designed with multiple positioning projections to increase adjustment range, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The covering element serves multiple functions simultaneously: it provides aesthetic coverage, ensures security by maintaining a narrow gap, enables adjustment through positioning projections, and protects the hinge adjusting notch. This multi-functionality reduces the need for separate components, thereby managing complexity while providing comprehensive adjustment capability.
Solution Approach 2:
The covering element combines several functions into a single integrated component: aesthetic coverage, security maintenance, adjustment positioning, and notch protection. By merging these functions into one element rather than using separate components, the overall device complexity is reduced while achieving the desired adjustment range.
