Solution Overview
Problem
Existing splicing devices for strip or sheet materials require manual operator intervention, leading to reduced productivity, safety risks, and imperfect alignment of welding and cutting zones with rolling means, resulting in weakened or incomplete splicing due to variations in material elasticity and mechanical characteristics.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual operator intervention is used to position the welding and cutting zone, then certain parameters such as product elongation can be taken into account, but the positioning remains approximate and involves long downtime reducing productivity
Solution Approach 1:
The patent replaces manual mechanical positioning with an automated mechanical transport system that moves the product between workstations. The positioning is achieved through controlled mechanical displacement of the product rather than manual operator intervention, eliminating both the imprecision and downtime associated with manual positioning while maintaining adaptability to material characteristics.
2Ease of operation
If manual intervention is used for positioning, then operator dexterity requirements are reduced, but operator safety is compromised due to engagement of hands and arms in the splicing device
Solution Approach 1:
The patent extracts the operator from the hazardous zone by implementing automated positioning systems that eliminate the need for manual intervention in the splicing device. The operator's hands and arms are completely removed from the danger area, while the automated system handles all positioning operations, thereby maintaining ease of operation while eliminating safety risks.
3Productivity
If mechanical means of restraint and traction are used to move the product, then the positioning should be consistent, but offsets occur due to variations in product stretching and mechanical characteristics
Solution Approach 1:
The patent implements a dynamic positioning system that adapts to variations in product mechanical characteristics. The system uses adjustable mechanical means that can be configured for different material properties, allowing consistent positioning despite variations in product stretching. The adaptability compensates for material variability while maintaining high automation levels and precision alignment.
4Manufacturing precision
If the welding and cutting zone is not precisely aligned with rolling means, then parts of the product may be weakened by untimely rolling or may tear during subsequent tensioned movement
Solution Approach 1:
The patent uses automated mechanical transport systems with precise control to ensure accurate alignment between the welding and cutting zone and the rolling means. This eliminates the misalignment that causes product weakening and tearing, while the automated system maintains consistent positioning across multiple operations, thereby preserving product strength.
