Solution Overview

Problem

Existing winding machines face challenges in handling large, heavy reels of cellulose-based covering tape, which are cumbersome and costly to replace with smaller, lighter reels suitable for precise and rapid motion around palletized loads.

Innovation Solution

A machine that unwinds and rewinds covering tape from a large reel into multiple smaller reels using a support shaft system with rotating tubular supports and contrast rollers, allowing for precise control and automation of the process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If large sized reels of covering tape are used, then the environmental impact is reduced through cellulose-based material, but the weight and inertia considerably complicate the apparatuses necessary to move them with precision and rapidity

Engineering Contradiction:
Improveenvironmental impactVSAvoidapparatus complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent applies segmentation by dividing the large reel into multiple smaller reels. The unwinding shaft receives the large reel and progressively winds the tape onto multiple smaller reels mounted on rewind shafts. This allows the system to use environmentally friendly large reels for storage while creating manageable smaller reels for actual wrapping operations, thus reducing both environmental impact and operational complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces an intermediary machine (the rewinding apparatus with unwinding and rewind shafts) that acts as a mediator between the large storage reels and the smaller operational reels. This intermediary device enables the transition from large environmentally-friendly reels to smaller handling-friendly reels, resolving the contradiction between environmental considerations and operational simplicity.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Speed

If smaller and lighter reels of covering tape are used, then handling precision and rapidity are improved, but the purchase costs would be higher as they are not a production standard

Engineering Contradiction:
Improvehandling speedVSAvoidcost
Core Design Contradiction:
SpeedVSEase of manufacture

Solution Approach 1:

The patent implements self-service by enabling the system to automatically create its own smaller reels from standard large reels through the rewinding process. The unwinding shaft and multiple rewind shafts work together to automatically portion the tape from large standard reels into smaller reels suitable for rapid handling, eliminating the need to purchase specialized smaller reels and thus reducing costs while maintaining high handling speed.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent applies parameter changes by transforming the reel size parameter dynamically. The system takes standard large reels as input and through the controlled winding process on multiple rewind shafts, produces smaller reels with optimized dimensions for speed and precision handling. This parameter transformation allows the system to maintain cost-effectiveness while achieving high handling performance.

Inventive Principle:
Principle #35Parameter changes

3Quantity of substance

If a single large reel is used, then the quantity of covering tape is sufficient for multiple palletised loads, but the reel cannot be easily replaced and the winding machine would need to be stopped for an extended period

Engineering Contradiction:
Improvequantity of covering tapeVSAvoidproductivity
Core Design Contradiction:
Quantity of substanceVSProductivity

Solution Approach 1:

The patent applies segmentation by dividing the single large reel's worth of tape into multiple smaller reels created on the rewind shafts. As each smaller reel is completed, it can be independently replaced without stopping the entire operation. This segmentation maintains the total quantity of covering tape available while dramatically improving productivity through continuous operation and easy reel replacement.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements continuity of useful action by enabling uninterrupted tape supply through multiple rewind shafts. While one reel is being used, another can be prepared or replaced simultaneously. The system maintains continuous operation without stopping the winding machine, thus preserving both the sufficient quantity of tape and high productivity throughout the wrapping process.

Inventive Principle:
Principle #20Continuity of useful action
