Sliding Pivot Hinge in Door Panel for Adjustable Axis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door constructions with pivot hinges are limited in flexibility as the pivot hinges are fixed in a predetermined position within the door panel, restricting the ability to adjust the pivot axis according to the door's usage conditions.
Innovation Solution
A door construction with slideable pivot hinges integrated into the door panel's sides, featuring a guide profile and attachment means that allow the pivot hinges to be positioned and adjusted along the panel's length, enabling flexible selection of the pivot axis and facilitating easier maintenance and installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the pivot hinge is fixed in a predetermined position within the door panel, then the door construction is simple and easy to manufacture, but the flexibility to adjust the pivot axis according to usage conditions is restricted
Solution Approach 1:
The pivot hinge is designed to be movable along the side of the door panel through a guide profile, transforming the fixed position into an adjustable one. The attachment means allow the pivot hinge to be secured at different positions, enabling dynamic adaptation of the pivot axis location while maintaining a relatively simple overall structure.
2Productivity
If the pivot hinge is built into the door panel at a predetermined position, then the manufacturing process is straightforward, but the ability to optimize door rotation performance for different door widths is limited
Solution Approach 1:
The guide profile enables the pivot hinge to be positioned at optimal locations depending on door width and usage requirements. This dynamic positioning capability allows optimization of rotation performance without requiring custom manufacturing for each door size, as the same door panel with guide profile can accommodate different pivot hinge positions.
3Reliability
If the pivot hinge is fixed in position, then the structure is stable and simple, but wear cannot be reduced through repositioning and the lifespan is limited
Solution Approach 1:
The movable pivot hinge design allows repositioning to optimize wear distribution. The guide profile provides a controlled path for movement, and the attachment means enable secure positioning at different locations, extending the pivot hinge lifespan through strategic repositioning while maintaining structural integrity.
4Ease of repair
If the pivot hinge is fixed in the door panel, then installation is simple, but maintenance requires disassembling the entire door construction
Solution Approach 1:
The door construction is segmented into modular components: the door panel with guide profile, the movable pivot hinge, and the attachment means. This segmentation allows the pivot hinge to be independently accessed, removed, and maintained without disassembling the entire door construction, significantly improving maintenance accessibility.
