Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional beating method is used to disassemble iron sleeve from bushing, then disassembly can be achieved, but lots of manpower is consumed and components are prone to deformation and damage
Solution Approach 1:
The patent introduces a disassembling device as an intermediary tool between the operator and the iron sleeve-bushing assembly. This device includes a pushing component with a pushing head that contacts the iron sleeve, a clamping component with clamping jaws that grip the bushing, and a rotating component that converts rotational motion into axial separation force. The intermediary device distributes forces evenly and prevents direct impact on components, thereby reducing manpower consumption while maintaining component integrity.
Solution Approach 2:
The patent replaces the traditional direct beating method with a controlled mechanical separation system. Instead of applying uncontrolled impact forces, the device uses a rotating component with cam surfaces or threaded mechanisms to convert rotational input into gradual axial separation. This substitution transforms a high-impact, low-control process into a low-impact, high-control process, reducing both manpower requirements and risk of component damage.
2Productivity
If pounding force is applied to disassemble iron sleeve, then detachment can be achieved, but force deviation causes deformation and damage making disassembly difficult
Solution Approach 1:
The disassembling device acts as a precision intermediary that ensures force application at the exact center of the iron sleeve. The pushing head is designed with a geometry that matches the iron sleeve's inner surface, ensuring concentric contact. The rotating component provides guided motion that maintains alignment throughout the separation process, preventing any lateral deviation that could cause deformation.
Solution Approach 2:
The clamping component performs preliminary action by securely gripping the bushing before separation begins. This preliminary clamping stabilizes the assembly, preventing movement or misalignment during the separation process. The device is positioned and aligned with the iron sleeve-bushing assembly before applying separation force, ensuring that all subsequent actions occur with precise centering.
3Adaptability or versatility
If adjustable clamping is used to accommodate various sizes, then versatility is improved, but device complexity increases
Solution Approach 1:
The patent implements adjustability through parameters such as the opening width of the clamping jaws and the diameter of the pushing head. These parameters can be modified to accommodate different sizes of iron sleeves and bushes. The clamping jaws can be adjusted to different positions along the axial direction, and the pushing head can be selected or adjusted to match different inner diameters, providing versatility without requiring completely different devices for each size.
Solution Approach 2:
The disassembling device is designed with universal features that allow it to handle multiple sizes and types of iron sleeve-bushing assemblies. The clamping component can accommodate various outer diameters through adjustable jaw positions, while the pushing component can adapt to different inner diameters. This multi-functionality is achieved through standardized adjustment mechanisms rather than multiple specialized tools, balancing versatility with structural simplicity.
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
The solution enables efficient, effort-saving, and damage-free disassembly of iron sleeves from drag arm bushings, accommodating various sizes through adjustable clamping surfaces and an arc gasket, ensuring smooth detachment without damaging the components.
Implementation Method 1
The first screw has a first end for screwing into the first threaded hole and a second end opposite to the first end. The bolt nut is screwed on the second end of the first screw inserted into an iron sleeve of a drag arm for positioning the iron sleeve between the top push casing and the bolt nut and making the iron sleeve be clamped by the top push casing and the bolt nut.
Implementation Method 2
The second screw is inserted into the second threaded hole of the casing for screwing on the casing and is provided with a push piece for contacting an outer surface of the closed end of the top push casing. When the second screw is rotated, the push piece of the second screw pushes forwards the top push casing to detach the iron sleeve inserted by the first screw and clamped by top push casing and the bolt nut from the bushing of the drag arm.
Implementation Method 3
an inner surface of the arc wall of the casing is provided with an arc gasket for reducing an inner diameter of the arc wall of the casing
