Solution Overview
Problem
The manual adjustment of frictional force in the reinforcing layer of rubber hoses is time-consuming and inefficient, requiring manual adjustment of each section in spiral machines, which increases manufacturing costs and time.
Innovation Solution
An automated adjustment device for the frictional force adjustment portion, including a rotary shaft rotating actuator, an adjustment member, an adjustment member driving actuator, a support member, a movement mechanism, a tilt tolerance mechanism, a pressure detection portion, and a frictional force control unit, which automatically adjusts the frictional force within a predetermined range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual adjustment is performed for each section one-by-one, then the frictional force can be adjusted to fall within the set value range, but the adjustment time becomes excessively long
Solution Approach 1:
The patent merges multiple adjustment operations into a single automated device that can simultaneously adjust multiple sections. The adjustment device includes a support member that can hold multiple sections, and an adjustment member that can simultaneously engage with and adjust the frictional force of multiple sections, thereby combining what was previously separate manual operations into one unified automated process.
Solution Approach 2:
The patent replaces the manual mechanical adjustment system with an automated adjustment device. The device uses a drive mechanism to automatically rotate the adjustment member, eliminating the need for manual operation. The system substitutes human labor with automated mechanical systems that can perform adjustments more quickly and consistently.
2Productivity
If the number of bobbins and sections is increased to meet production requirements, then the productivity increases, but the total adjustment time increases proportionally
Solution Approach 1:
The adjustment device combines multiple section adjustment capabilities into a single device. The support member can simultaneously hold and adjust multiple sections, meaning that increasing the number of sections processed does not linearly increase the adjustment time. This merging approach allows the system to maintain efficiency even as production capacity scales.
Solution Approach 2:
The adjustment device is designed with universal functionality to handle multiple sections simultaneously. The adjustment member and support member are configured to work with multiple sections in parallel, making the device adaptable to different production volumes without requiring proportional increases in adjustment time.
3Manufacturing precision
If manual adjustment operations are performed for hundreds of sections, then each section can be individually optimized, but the labor intensity and operational complexity increase significantly
Solution Approach 1:
The patent replaces manual adjustment operations with an automated adjustment device. The drive mechanism automatically rotates the adjustment member to engage with each section, eliminating the need for operators to manually manipulate each section. This substitution maintains individual section optimization while dramatically reducing operational complexity and labor intensity.
Solution Approach 2:
The adjustment device is designed to automatically perform adjustment operations without requiring manual intervention for each section. The system self-regulates the adjustment process through automated rotation and engagement mechanisms, allowing individual sections to be optimized without human operators needing to perform repetitive manual tasks.

AI summary
In an adjustment device for a frictional force adjustment portion in a section, an inner circumferential portion of the section includes: a support hole formed from rolling bearings at both ends; a frictional force generation portion configured of a brake shoe, a coil spring, and a hexagon socket set screw and generates a frictional force against a rotary shaft inserted into the support hole; and a frictional force adjustment portion configured of the hexagon socket set screw and adjusts the frictional force in the frictional force generation portion. The adjustment member driving actuator adjusts the frictional force of the frictional force adjustment portion by rotating normally and reversely the adjustment member such that the frictional force in the frictional force generation portion of the section falls within a predetermined range.
