Dual Swing Door Operator System for Heavy Doors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Standard swing door operators often lack sufficient momentum to operate heavier or larger swing doors, necessitating custom-made operators that are expensive and time-consuming to manufacture.
Innovation Solution
A swing door operator system comprising two standard operators, one on each side of the door leaf, interacting to move the door between open and closed positions, with a control unit regulating their operation and a drive unit comprising a motor and spring to exert a combined force, allowing for the use of smaller operators on larger or heavier doors without significant rebuilding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a standard swing door operator is used, then the device complexity is low and cost is reduced, but the momentum and force are insufficient for heavy or large swing doors
Solution Approach 1:
The door operator system is segmented into two separate standard door operators instead of using one large custom operator. Each operator is mounted on opposite sides of the door and works cooperatively to provide the necessary combined force and momentum to move heavy or large doors, while maintaining the simplicity and standardization of individual operator units.
2Force
If a custom-made swing door operator is manufactured, then the force and momentum are sufficient for heavy doors, but the manufacturing time and cost increase significantly
Solution Approach 1:
Instead of manufacturing one custom operator, the system uses two off-the-shelf standard operators that can be purchased and installed immediately. This segmentation approach eliminates custom manufacturing wait times while achieving the required force through cooperative operation of the two standard units.
Solution Approach 2:
Two standard door operators are merged into a cooperative system where both operators work simultaneously on the same door. The combined output of both operators provides the necessary force and momentum for heavy doors, achieving custom-operator performance through standard-component combination.
3Force
If a single large swing door operator is used, then the force capacity is sufficient, but the device becomes more expensive and complex
Solution Approach 1:
The single large operator is segmented into two smaller standard operators. Each operator handles a portion of the workload, and their combined effect provides the total force capacity needed. This segmentation reduces device complexity by using standard components rather than a single large custom unit.
Solution Approach 2:
The system changes the operational parameters by having two operators work in coordination rather than one operator working alone. The control system regulates the operation of both operators to optimize their combined force output, achieving the performance of a large operator through parameter-controlled cooperation of smaller units.
