Synchronized Parallel Electromagnetic Push Rods for Compact Storage Doors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door opening devices for storage equipment require large electromagnetic push rod structures to provide sufficient force, which increases the height of the equipment and complicates transportation and installation, especially for larger volumes.
Innovation Solution
A door opening device utilizing multiple electromagnetic push rod structures arranged in parallel, connected through an output joint, with adjustable stroke and synchronized operation to reduce thickness while maintaining pushing force, and allocating driving force to the initial stage for enhanced practicality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a single electromagnetic push rod structure is used to open the door, then the structure is simple, but the pushing force is insufficient and the thickness must be increased to provide adequate force
Solution Approach 1:
The patent divides the single electromagnetic push rod structure into multiple parallel push rods (at least two). Each push rod provides a portion of the total pushing force, allowing the system to achieve sufficient force output while keeping each individual push rod compact with reduced thickness.
2Force
If multiple electromagnetic push rod structures are arranged in parallel to increase pushing force, then the pushing force is sufficient, but the thickness of the door opening device increases
Solution Approach 1:
Instead of arranging multiple push rods in the thickness direction (which would increase the 3rd dimension), the patent arranges them in parallel along the width or length direction. This dimensional reconfiguration allows multiple push rods to work together for increased force while maintaining a compact thickness profile.
3Force
If the electromagnetic push rod structure is enlarged to provide sufficient pushing force, then the door can be opened stably, but the height of the entire storage equipment increases
Solution Approach 1:
The patent segments the force generation function across multiple parallel push rods rather than using one large push rod. This segmentation allows the system to achieve the required total pushing force through multiple smaller units, preventing an increase in the overall height of the storage equipment.
4Reliability
If a single push rod is used, then the device is compact, but wear or looseness directly impacts door opening performance
Solution Approach 1:
The patent connects the multiple push rods to a common output joint through position-adjustable connections. This allows each push rod to be independently positioned and adjusted, ensuring that wear or looseness in one push rod does not compromise the overall system. The local adjustability maintains reliability while managing the complexity of having multiple push rods.
