Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Elevator door engagement devices face challenges in accommodating varying distances between landing and car doors, leading to inefficiencies in installation and increased workload due to the need for custom measurements, which affects shipping schedules and work efficiency.
Innovation Solution
A door engagement device with a changeable engaging part position relative to a base, allowing for adjustable alignment to match different door distances, featuring elongated holes and jack members for precise positioning, enabling a single device to fit various elevator configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the engagement device is designed to be suitable for elevators with small depth distance, then the device can be adopted in elevators with small depth distance, but the engaging part needs to be raised using sim or spacer in elevators with given depth distance, decreasing work efficiency
Solution Approach 1:
The engaging part is made adjustable in position through elongated holes that allow movement along the depth direction. The jack member enables dynamic adjustment of the engaging part's position to match different depth distances between car door and landing door, eliminating the need for fixed-position designs or additional spacers.
Solution Approach 2:
The position parameter of the engaging part is made changeable through the combination of elongated holes and jack member. This allows the engagement device to adapt to different depth distance parameters in various elevator models without requiring custom designs or additional components.
2Manufacturing precision
If actual measurement of depth distance is performed for each elevator, then the engagement device can be precisely fitted, but the workload increases and may influence shipping schedule
Solution Approach 1:
The engagement device is designed with universal adaptability through the adjustable engaging part mechanism. A single standard design can be applied to multiple elevator models with different depth distances, eliminating the need for custom measurements and production for each unit.
Solution Approach 2:
The elongated holes and jack member are pre-configured in the engagement device to enable easy adjustment during installation. This preliminary design preparation allows installers to quickly adapt the device to different depth distances without requiring complex measurement and customization processes.

AI summary
Provided is a door engagement device including an engaging body including an engaging part, the engaging part being configured to engage with an engaged part provided on a driven door that is either one of the landing door and the car door of an elevator, and transmit a driving force that moves a driving door in an opening and closing direction to the driven door, the driving door being the remaining one of the landing door and the car door; and a base that is connected to the driving door and the engaging body. The position of the engaging part is changeable relative to the base in an aligning direction, in which the landing door and the car door align with each other when the landing and car doors are opened and closed.
