Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fiberglass cutting devices require disassembly to adjust tension between the anvil roller and cutting roller, leading to inefficiencies and uneven compression, which affects cutting performance.
Innovation Solution
A fiberglass cutting device with a yoke-supported adjustable roller system, allowing on-the-fly adjustment of the anvil roller's position using a single tension-adjusting knob, ensuring parallel alignment and maintaining even compression between the rollers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the anvil roller is supported at a single end (cantilevered arrangement), then the device structure is simplified, but the compression becomes uneven across the width of the anvil roller and the roller becomes unstable
Solution Approach 1:
The yoke is divided into two arms that independently support each end of the anvil roller, transforming the single-point support into a distributed two-point support system. This segmentation provides stability and ensures even compression across the roller width while maintaining structural simplicity.
2Ease of operation
If two tension-adjusting knobs are used (one for each side of the anvil roller), then the tension adjustment is more distributed, but the device complexity increases and the resulting roller position is likely not parallel to the cutting roller
Solution Approach 1:
Two separate tension adjustment mechanisms are merged into a single yoke-supported adjustment system. The single knob controls both yoke arms simultaneously through the threaded rod mechanism, ensuring parallel roller positioning and even compression while reducing the number of adjustment components.
Solution Approach 2:
The yoke acts as an intermediary mechanism between the single adjustment knob and the anvil roller. It translates the linear motion of the threaded rod into synchronized movement of both yoke arms, ensuring equal and parallel adjustment of the roller position.
3Measurement precision
If disassembly is required to adjust tension between rollers, then the adjustment can be precise, but the workflow is interrupted and time is lost
Solution Approach 1:
The tension adjustment mechanism is made dynamic and adjustable during operation. The threaded rod and knob assembly allow real-time modification of the anvil roller position while the machine is running, enabling continuous workflow without disassembly while maintaining precise compression control.
4Ease of manufacture
If the anvil roller diameter decreases continuously due to consumption, then the softer anvil roller can be replaced, but the compression is continuously lost requiring frequent adjustments
Solution Approach 1:
The system allows dynamic change of the compression parameter through the adjustable yoke mechanism. As the anvil roller diameter decreases from consumption, the operator can adjust the yoke position to compensate and maintain consistent compression, extending the usable life of the roller and ensuring reliable cutting performance.
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 with improved cutting performance by allowing for precise and parallel adjustment of the anvil roller relative to the cutting roller, reducing downtime and ensuring consistent fiber cutting.
Implementation Method 1
The axle is held in position by a threaded rod, its position controlled by an external knob. Rotation of the external knob moves the threaded rod toward or away from the axle, which in turn pushes or releases the anvil roller with respect to the cutting roller, adjusting compression.

AI summary
The disclosed fiberglass cutting device with yoke-supported adjustable roller is a device, or “gun,” with on-the-fly—during operation adjustment of the spacing between the anvil roller and cutter. This adjustability is accomplished using only a single tension-adjusting knob located to one side of the anvil roller. This is superior to the prior art that required, at a minimum, two tension-adjusting knobs—one for each side of the anvil roller. To solve this problem, the fiberglass cutting device with yoke-supported adjustable roller supports the supports the anvil roller on both ends using a yoke. The position of the yoke is controlled by a single tension-adjustment knob that moves both arms of the yoke, thus maintaining the anvil roller in a position parallel to the cutting roller. The use of the yoke also avoids only supporting the anvil roller at a single end, which creates an unstable cantilevered-roller.
