Clutchable Winch Detachable Head for Continuous Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional clutchable winches require repeated removal and reinsertion of a bar to rotate the belt, leading to time and force consumption due to the integral welding of the head portion with the shaft member, which interferes with vehicle carriers when rotated.
Innovation Solution
A clutchable winch design featuring a tube, a circular fitting piece with a central hole, a column, a sleeve with a groove and apertures, a positioning disc with inclined teeth, an actuating plate with hexagonal pores, and a compression spring, allowing the bar to be pressed downward and pulled upward without removal for continuous belt operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the head portion is integrally welded with the shaft member, then the structure is simple and strong, but the bar interferes with vehicle carriers when rotated requiring repeated removal and reinsertion
Solution Approach 1:
The head portion is separated from the shaft member through a detachable connection mechanism featuring a positioning disc with first inclined teeth and an actuating plate with second inclined teeth. This segmentation allows the bar to be removed from one aperture and inserted into another without complete disassembly, resolving the interference issue while maintaining structural integrity during operation.
2Ease of operation
If the bar is removed and reinserted repeatedly to rotate the belt, then the interference problem is solved, but time and force are consumed
Solution Approach 1:
The connection between the head portion and shaft member is made dynamic and adjustable through the detachable toothed mechanism. The bar can be quickly released from one position and repositioned to another by actuating the plate, which engages the inclined teeth to facilitate smooth transitions. This dynamic system eliminates the need for complete removal and reinsertion, significantly improving operating efficiency while maintaining operational flexibility.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables continuous operation by allowing the bar to be pressed downward and pulled upward directly, reducing operating time and force consumption by eliminating the need for repeated bar insertion and removal.
Implementation Method 1
a compression spring defined between the actuating plate and the fitting piece of the tube
Implementation Method 2
a positioning disc fixed on a bottom end of the groove of the sleeve, including a number of first inclined teeth arranged around an outer wall thereof... an annular actuating plate fitted on the column, including a plurality of second inclined teeth disposed on one end surface thereof to correspond to the first inclined teeth
