Spooling Arbor Projections for Uniform Cord Winding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for spooling cord-like materials fail to achieve uniform spooling, often resulting in tangles, knots, and weak spots, which shorten the lifespan of the material and prolong the spooling process.
Innovation Solution
A spooling system that incorporates a standard variable speed drill bit and arbor with projections, allowing for one-handed operation to guide and coil the line without tangles or knots, using a hexagonal driver bit to connect to a power source for efficient and uniform spooling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional manual spooling methods are used, then the spooling process can be performed without specialized equipment, but the resulting spool has tangles, knots, and weak spots that reduce material lifespan
Solution Approach 1:
The patent replaces manual mechanical spooling operations with a powered drill system. The drill motor provides consistent rotational force to the arbor, eliminating the variability and inconsistency of manual hand-cranking, thereby producing uniform spooling without tangles or knots while maintaining efficient spooling speed.
Solution Approach 2:
The patent introduces variable speed control to the drill system, allowing the operator to adjust rotational speed parameters based on the specific cord material and spooling requirements. This parameter control enables optimization of spooling quality and speed, achieving both high reliability and time efficiency.
2Productivity
If traditional spooling methods are used, then no specialized attachment is needed, but the spooling process creates knots and tangles that require frequent stopping and repositioning
Solution Approach 1:
The patent divides the spooling function into separate components: a spool body for holding the cord, an arbor for rotation, and a drill attachment mechanism. This segmentation allows each component to be optimized independently and facilitates easy assembly, disassembly, and operation, reducing overall operational complexity despite the added functionality.
Solution Approach 2:
The patent introduces a hexagonal driver bit as an intermediary component that connects the drill to the arbor. This standardized interface simplifies the connection process, allows for quick attachment and detachment, and enables the use of common drill bits, thereby maintaining ease of operation while enabling powered spooling.
3Adaptability or versatility
If a fixed-speed motor is used for spooling, then the system is simpler, but it cannot adapt to different cord materials and spooling requirements
Solution Approach 1:
The patent designs the arbor with a universal hexagonal interface that can accommodate standard hexagonal driver bits from various drills. This universal design allows the same spooling apparatus to work with different drill types and speeds, providing adaptability to various cord materials without increasing the complexity of the spooling mechanism itself.
Solution Approach 2:
The patent incorporates variable speed capability into the system, allowing the rotational speed to be dynamically adjusted based on the specific cord material, diameter, and spooling requirements. This dynamic adjustment provides versatility for different applications while maintaining a relatively simple mechanical structure that leverages the drill's existing speed control capabilities.
