Portable Distribution Transformer Hoisting Rack with Segmented Hold Hoop
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing portable distribution transformer hoisting racks have a strenuous mounting process due to the loose-leaf hold hoop, which results in poor safety performance and increased operational complexity.
Innovation Solution
An improved portable distribution transformer hoisting rack design featuring a loose-leaf hold hoop with a third hold hoop between two symmetric hold hoops, a rotatable supporting rod, and a length-adjustable adjusting rod, allowing for simplified mounting and enhanced stability through adjustable gaps and connections, along with a hoisting assembly for efficient equipment handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a loose-leaf hold hoop with two fastening portions is used to mount the supporting rod to the mast, then the hoisting rack can be assembled, but the mounting process becomes strenuous and the hoop easily slides when one fastening portion is loosened
Solution Approach 1:
The hold hoop is divided into three separate hoop bodies (first, second, and third hold hoop bodies) instead of two. Each hoop body has its own fastening portions that can be independently mounted to the mast, eliminating the sliding problem of the two-part design while simplifying the mounting process through modular assembly.
Solution Approach 2:
The third hold hoop body acts as an intermediary element between the first and second hold hoop bodies. It provides an additional mounting point on the mast that stabilizes the entire assembly, preventing the sliding issue that occurred when loosening fastening portions in the two-part design.
2Stability of the object's composition
If a loose-leaf hold hoop with multiple fastening portions is used, then the supporting rod can be fixed to the mast, but the mounting process becomes complex and time-consuming
Solution Approach 1:
By segmenting the hold hoop into three independent hoop bodies, each with its own fastening portions, the mounting process becomes more systematic and less complex. The segmented design allows for sequential mounting without requiring complex coordination of multiple fastening operations simultaneously.
Solution Approach 2:
Each hold hoop body is pre-configured with its own fastening portions, allowing them to be mounted to the mast in a straightforward sequence. This preliminary preparation of each segment reduces the overall mounting time compared to assembling a complex multi-fastening structure.
3Device complexity
If a fixed hold hoop design is used, then the structure is simple, but it lacks adaptability to different mounting positions and environments
Solution Approach 1:
The hold hoop is segmented into three independent hoop bodies that can be mounted at different positions on the mast. This segmentation provides adaptability to various mounting environments and positions while keeping each individual hoop body structurally simple.
Solution Approach 2:
The design transitions from a fixed hold hoop to a dynamic, multi-segment configuration where each hoop body can be independently positioned and adjusted. This dynamic arrangement enhances adaptability to different mounting scenarios while maintaining structural simplicity through modular design.
