Solution Overview

Problem

Existing winding devices face challenges in applying and maintaining a consistent force for the pressure roller during the movement of the support element, leading to air inclusions and complex adjustments between the bearing arm and support arm.

Innovation Solution

The introduction of a positive guiding element that controls the movement of the bearing arm relative to the support arm, coupled with a drive mechanism such as a pneumatic cylinder or electric motor, ensures the pressure roller follows a defined path and maintains a consistent pressing force, even during the movement of the support element.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the pressure roller is mounted in a bearing arm that is movable relative to the support arm, then the pressure roller can follow the movement of the support element, but it becomes difficult to apply and maintain the desired force against the winding

Engineering Contradiction:
Improveconsistent force applicationVSAvoidadjustment complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The bearing arm is made movable relative to the support arm through a guide track system, allowing the pressure roller to dynamically follow the support element's movement while maintaining contact with the winding. The guide track constrains the movement to a specific path, ensuring reliable force application throughout the motion range.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The guide track acts as an intermediary element between the support arm and bearing arm, mediating the relative movement while maintaining proper force transmission. This intermediary structure simplifies the connection and eliminates the need for complex actuators.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If an actuator is used to adjust the bearing arm and support arm relative to each other, then the pressure roller can maintain contact with the winding, but the device becomes more complex

Engineering Contradiction:
Improvecontact maintenanceVSAvoidactuator requirements
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The bearing arm automatically maintains contact with the winding through its own weight and the geometric constraints of the guide track, eliminating the need for external actuators. The system self-regulates the pressure roller's position throughout the support element's movement.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The guide track serves as a passive intermediary that guides the bearing arm's movement without requiring active control mechanisms. This mechanical guidance system replaces complex actuator assemblies while maintaining reliable contact.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If the support arm moves relative to the machine frame during support element movement, then the winding position changes, but the pressure roller must follow a defined path to maintain consistent pressure

Engineering Contradiction:
Improvemovement flexibilityVSAvoidpressure consistency
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The bearing arm is designed to dynamically adapt its position relative to the support arm through the guide track, allowing it to follow the support element's movement while maintaining a consistent defined path. This dynamic adjustment ensures pressure consistency despite support arm motion.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The guide track acts as a precision intermediary that translates the support arm's movement into a controlled bearing arm path. This mechanical linkage ensures the pressure roller follows the exact required trajectory to maintain consistent pressure on the winding.

Inventive Principle:
Principle #24Intermediary (Mediator)
