Cable Drive Unit Lateral Displacement for Reduced Wear
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cable drive units for free stall cleaning systems suffer from premature cable wear due to friction with the chain guide, and they are limited by fixed support frames that restrict their use in areas with restricted space.
Innovation Solution
A cable drive unit with a design that allows the support frame and drum to move laterally with respect to the base frame, eliminating friction by keeping the cable aligned and reducing wear, while also enabling operation in confined spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a chain guide is used to align the cable during winding, then cable alignment is improved, but cable wear increases due to friction
Solution Approach 1:
The patent removes the chain guide component entirely from the system. Instead of using a chain guide to align the cable, the invention uses a cable guide pulley that redirects the cable without applying pressure or friction, thereby eliminating the harmful friction-induced wear while maintaining proper cable alignment during winding operations
Solution Approach 2:
The patent introduces a cable guide pulley as an intermediary component between the cable and the drum. This pulley serves as a mediator that guides the cable along the correct path without direct contact or friction with the cable, unlike the chain guide that pressed against the cable. The pulley's rotating surface allows the cable to pass through with minimal friction while maintaining alignment
2Stability of the object's composition
If a fixed support frame is used, then structural stability is improved, but adaptability to restricted spaces deteriorates
Solution Approach 1:
The patent transforms the fixed support frame into a movable support frame that can reciprocate along the base frame. This dynamic adjustment capability allows the drum and associated components to be repositioned as needed, enabling the system to adapt to various alley lengths and restricted spaces while maintaining structural stability during operation through the guidance of rails
3Ease of operation
If the drum is fixed in position, then ease of operation is improved, but cable alignment during winding deteriorates
Solution Approach 1:
The patent inverts the traditional approach by making the drum movable rather than fixed. Instead of using a fixed drum with a chain guide to force cable alignment, the movable drum reciprocates in synchronization with cable winding, allowing the cable to naturally align with the drum's movement. This inversion eliminates the need for friction-based alignment mechanisms while maintaining proper cable positioning
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 significantly reduces cable wear, extends the cable's lifespan, and allows for more flexible installation in various free-stall-cleaning layouts, including those with restricted space, thereby reducing downtime and maintenance costs.
Implementation Method 1
a worm gear being pivotally mountable about the support frame within a given span, said worm gear being threadedly engageable within a fixed component of the base frame so that a rotation of the worm gear in turn drives a lateral displacement of the support frame with respect to the base frame
