Adjustable Elevator Door Coupler for Multiple Landing Door Types
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing elevator systems require multiple different elevator door coupler systems to accommodate various landing door types, leading to increased production costs and time due to the need for custom designs.
Innovation Solution
An elevator door coupler system with a door hanger featuring adjustable mounting positions for a coupling assembly through elongate openings, allowing compatibility with diverse landing door systems without requiring larger components or reducing strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple different elevator door coupler systems are manufactured to accommodate various landing door types, then compatibility with diverse landing door systems is improved, but production cost and time increase
Solution Approach 1:
The door hanger is designed with an elongate opening that allows a single coupler system to accommodate multiple landing door types by adjusting the mounting position of the coupling assembly. This universal design eliminates the need to manufacture multiple different coupler systems for different landing door configurations, directly resolving the contradiction between versatility and production efficiency
Solution Approach 2:
The coupling assembly can be dynamically repositioned along the elongate opening of the door hanger to adapt to different landing door roller placements. This adjustability feature allows the same hardware to function with various landing door types without requiring custom-designed coupler systems, thereby maintaining compatibility while reducing production complexity
2Adaptability or versatility
If the door hanger size is increased to accommodate adjustable mounting positions, then adaptability to different landing door dimensions is improved, but the size and complexity of components increase
Solution Approach 1:
Instead of increasing the overall size of the door hanger components, the invention introduces an elongate opening that provides adjustment capability along the length of the opening. This dimensional approach allows position variation without requiring larger mounting surfaces or more complex multi-component structures, thus achieving adaptability while maintaining component simplicity
3Ease of manufacture
If material is removed from coupling assembly components to create mounting openings, then ease of installation is improved, but structural strength is reduced
Solution Approach 1:
The elongate opening is strategically positioned and dimensioned to provide sufficient adjustment range while removing the minimum necessary material. The opening's location and size are optimized to maintain structural integrity of the coupling assembly components while still allowing easy installation and positioning adjustments, thus balancing ease of manufacture with structural strength

AI summary
An elevator door coupler system (1) includes a door hanger (12), for connection to an elevator car door (2) and at least one roller (14a, 14b), mounted to the door hanger (12). The door hanger (12) comprises a first elongate opening (54a, 54b, 60a, 60b, 62a, 62b, 64a, 64b, 66a, 66b, 68a, 68b, 70a, 70b) for fixedly mounting a coupling assembly (16) arranged to engage a landing door so as to actuate movement of the landing door together with movement of the elevator car door (2), such that a position of the coupling assembly (16) relative to the door hanger (12) is adjustable by mounting the coupling assembly (16) at a different position within the first elongate opening (54a, 54b, 60a, 60b, 62a, 62b, 64a, 64b, 66a, 66b, 68a, 68b, 70a, 70b).
