Telescopic Linear Operator for Adjustable Sliding Door Movement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The burden of acquiring a correctly sized linear operator for sliding doors, such as elevator doors, can be significant, as existing operators are not adjustable and must be specifically sized for each application.
Innovation Solution
A telescopic linear operator that can be selectively sized by translating an arm along a body, allowing the operator to be adjusted to fit various door movement requirements, thereby reducing the need for multiple operators of different sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If non-telescopic linear operators are used, then the operator can be installed, but multiple operators of different sizes must be stocked to cover various door movement requirements
Solution Approach 1:
The operator incorporates a telescopic arm that can be extended or retracted to different lengths, allowing a single operator to adapt to various door movement requirements. The arm includes multiple positioning holes that enable adjustment to different extension positions, providing dynamic adaptability without requiring multiple fixed-size operators.
Solution Approach 2:
The telescopic linear operator is designed as a universal device that can serve multiple applications with different door movement requirements. By combining the fixed body, telescopic arm, and adjustable positioning mechanism, a single operator type can replace multiple specialized operators, reducing inventory complexity.
2Adaptability or versatility
If a telescopic linear operator is used, then a single operator can serve multiple applications, but the device structure becomes more complex
Solution Approach 1:
The operator is segmented into distinct functional components: a fixed body, a telescopic arm with multiple sections, and a positioning mechanism. This segmentation allows the telescopic arm to be adjusted to different lengths while keeping the overall structure modular and manageable, reducing the complexity burden of the adjustable feature.
Solution Approach 2:
The operator's effective length parameter can be changed by adjusting the telescopic arm extension. The arm includes multiple positioning holes at different distances from the body, allowing the operator to change its effective length parameter to match different door movement requirements without requiring completely different operator designs.

AI summary
A linear operator for a sliding door includes a body; a first wheel rotatably attached to the body at a first position on the body; an arm movably attached to the body, translatable in a direction parallel or substantially parallel to a longitudinal axis of the body, and fixable to the body at a desired translation position; a second wheel rotatably attached to the arm at a second position on the arm; and a conveyor extending between the first wheel and the second wheel, movable about the first wheel and the second wheel, and operable for attachment to a door, wherein when the arm is at a desired translation position, a distance between the first position and the second position corresponds to a desired movement distance of the door when the door is attached to the conveyor.
