Two-Way Hinge Integrating Panel and Wicket Door Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing overhead doors require precise positioning and separate mounting of panel and door hinges, which is time-consuming and critical, affecting dimensional stability and assembly efficiency.
Innovation Solution
A two-way hinge integrating both panel and door hinges at a fixed 90-degree angle, allowing for simplified assembly and reduced dimensional requirements, with U-shaped mouldings providing play for panel edges and eliminating the need for separate finger protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate panel hinge and door hinge are mounted at 90 degrees to each other, then the wicket door and overhead door can function properly, but the assembly is time-consuming and positioning is critical
Solution Approach 1:
The patent combines the panel hinge and door hinge into a single integrated two-way hinge assembly. The two-way hinge incorporates both the panel hinge (for connecting overhead panels) and the door hinge (for supporting the wicket door) as unified components, eliminating the need for separate mounting operations and critical 90-degree positioning between separate hinges.
Solution Approach 2:
The two-way hinge serves multiple functions simultaneously: it acts as both the panel hinge for connecting overhead door panels and the door hinge for supporting the wicket door. This multi-functional design replaces what would traditionally require two separate hinge components mounted at specific angles to each other.
2Stability of the object's composition
If separate panel hinge and door hinge are mounted precisely at 90 degrees, then dimensional stability is achieved, but assembly complexity increases
Solution Approach 1:
By merging the panel hinge and door hinge into a single two-way hinge component, the patent eliminates the complexity of mounting two separate hinges at precise 90-degree angles. The integrated design inherently maintains the correct geometric relationship without requiring complex positioning procedures.
3Reliability
If U-shaped mouldings are fixed to panels, then secure retention is achieved, but assembly time increases
Solution Approach 1:
The two-way hinge is designed to automatically retain the U-shaped mouldings and panels through its own structure without requiring separate fastening operations. The hinge body itself provides the retention mechanism, eliminating the need for additional fixing steps while maintaining secure retention.
4Object-affected harmful factors
If finger protection is separately provided, then safety is ensured, but assembly time and cost increase
Solution Approach 1:
The finger protection feature is integrated directly into the two-way hinge structure rather than being provided as a separate component. The hinge body incorporates protective elements that prevent finger pinching during door operation, eliminating the need for separate finger protection components and their associated assembly steps.

AI summary
There is disclosed an overhead door comprising panels interconnected by means of panel hinges, and a wicket door provided in the overhead door, which is connected to the panels by means of door hinges. The panel hinges and the door hinges are integrated in one two-way hinge. The advantage is that it is no longer necessary to precisely position and mount the panel hinge and the door hinge, which must normally be mounted separately from each other, at an angle of 90 degree relative to each other, at the hinge side of the wicket door. Simple correct mounting of the two-way hinge at the location of the previous panel hinge will suffice, after which the door hinge integrated in the two-way hinge is automatically correctly mounted in a dimensionally stable manner as regards mounting orientation and position.
