Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing walking type winding machines face challenges in accurately controlling the film winding path, protecting critical components, and enhancing steering sensitivity, leading to cumulative errors and increased impact during collisions due to their large size and insensitive direction changes.
Innovation Solution
The implementation of a steering counting device with sensors and a front protection ring, combined with a DC brake motor and manual brake mechanism, allows for precise steering control, automatic braking, and improved sensitivity, while reducing machine body impact during collisions by using a modular and stable structural design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the machine body is made large to accommodate important components, then component protection is improved, but steering sensitivity deteriorates
Solution Approach 1:
The patent divides the machine into two distinct parts: a large machine body for housing components and a small steering part for directional control. The steering part can rotate independently relative to the machine body, allowing sensitive steering operations without requiring the entire large machine body to be maneuverable. This segmentation resolves the contradiction by isolating the steering function in a small, agile component while maintaining component protection in the large body.
Solution Approach 2:
The patent introduces rotational degrees of freedom between the steering part and machine body, adding a dimensional aspect to the system. The steering part can rotate around the machine body's longitudinal axis, and the entire assembly can move forward/backward along the machine body's longitudinal axis. This multi-dimensional movement capability allows the large machine body to remain protected while the steering part provides sensitive directional control.
2Device complexity
If path length is used to calculate winding path, then calculation simplicity is improved, but path control precision deteriorates
Solution Approach 1:
The patent incorporates sensors to detect the actual position and orientation of the machine body during movement. This feedback information is used to calculate the precise winding path in real-time, rather than relying solely on pre-calculated path lengths. The controller adjusts the winding path based on actual machine position data, ensuring high precision while maintaining relatively simple calculation methods through iterative refinement.
Solution Approach 2:
The patent performs preliminary calculations of the winding path based on expected machine movements, then refines these calculations using actual sensor data collected during operation. This two-stage approach allows the system to start with simple path length calculations and progressively improve precision as more information becomes available, balancing calculation simplicity with path control accuracy.
3Productivity
If the machine body is made large for winding capacity, then winding capability is improved, but collision impact increases
Solution Approach 1:
The patent separates the machine into a large machine body for winding operations and a small, lightweight steering part for navigation. The steering part acts as a buffer in collision scenarios, absorbing impact before it reaches the heavy machine body. This segmentation allows the system to maintain large winding capacity while reducing collision damage to critical components.
Solution Approach 2:
The patent positions the steering part at the front of the machine body, where it serves as a protective buffer against obstacles. The steering part's smaller mass and strategic positioning allow it to absorb collision impacts before they can damage the more valuable machine body components, providing beforehand cushioning against potential harm.

AI summary
A walking type winding machine includes a front protection ring being fixed on a steering part and a steering counting device. The steering counting device includes a first sensor for sensing the steering of a machine body, and the first sensor is connected to a controller of the walking type winding machine. The steering part includes a second sensor which is supported by an elastic component such that the second sensor is movably installed on the steering part, and the second sensor is used for sensing the backward movement of the frame of the steering part with respect to the second sensor. The walking type winding machine makes the control of a film winding path become simple and accurate, and it can protect important components of the steering part, improve walking steering sensitivity, and mitigate the impact on the machine body when colliding with an obstacle.
