Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing winches face issues with synchronous operation of the reciprocating screw and winding drum, leading to unordered winding of the traction rope, and lack of protection against debris entering the winding drum, which can cause damage.
Innovation Solution
A winch design that integrates a reciprocating screw rod with a driven wheel, a transmission component, and a retractable baffle component, ensuring synchronized movement between the winding drum and reciprocating screw, and incorporating O-rings and a guide sleeve to prevent debris entry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the reciprocating screw and winding drum are driven by two separate driving components, then each component can operate independently, but it becomes difficult to ensure synchronous operation, resulting in unordered winding of the traction rope
Solution Approach 1:
The patent combines the driving functions for the reciprocating screw and winding drum into a single driving component. The driving component includes a driving screw that directly drives the reciprocating screw, and a transmission mechanism that transfers power to the winding drum, ensuring both components operate synchronously from a single power source.
Solution Approach 2:
The patent introduces a transmission mechanism as an intermediary between the driving component and the winding drum. This transmission mechanism includes transmission wheels and belts that transfer rotational motion from the driving screw to the winding drum, coordinating their speeds and ensuring synchronous operation.
2Device complexity
If no mudguard is provided at the front end of the winding drum, then the structure remains simple, but matter such as sludge can easily enter the winding drum and cause damage during operation
Solution Approach 1:
The patent uses a flexible mudguard made of elastomeric material that can be molded into a three-dimensional shape. This mudguard is elastically deformable to adapt to the front end of the winding drum, creating an effective barrier against debris while maintaining a relatively simple overall structure.
Solution Approach 2:
The patent employs composite material construction for the mudguard, combining elastomeric materials with reinforcement structures. This allows the mudguard to provide effective protection against debris while maintaining flexibility and adapting to the winding drum's geometry without excessive complexity.
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
Ensures orderly winding of the traction rope and prevents damage from debris by synchronizing the movement of the winding drum and reciprocating screw, while also eliminating the need for a separate driving motor and protecting the winding drum from external matter.
Implementation Method 1
The reciprocating component includes a reciprocating screw rod rotatably connected to the support. One end of the reciprocating screw rod is fixedly connected with a driven wheel. Teeth fixed on the rope guide block to engage the reciprocating screw rod.
Implementation Method 2
The inner side walls of both ends of the guide sleeve connected with O-rings, each O-ring attached to the outer surface of the polished rod
