Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 3D printing, consumables on spools become loose during withdrawal, leading to jamming and reduced neatness, affecting the stability and efficiency of the printing process.
Innovation Solution
A consumable rewinding device with a driving assembly and roller system that rotates the consumable spool to rewind unused consumables, preventing loose distribution and jamming, utilizing a driving portion connected to a rotating shaft and a roller in contact with the spool to facilitate reverse rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the consumable is withdrawn from the printing head, then the consumable can be replaced or retrieved, but the consumable on the spool becomes loose and messy distributed
Solution Approach 1:
Instead of allowing the consumable to remain loose after withdrawal, the patent applies reverse rotation of the spool to rewind the consumable back onto itself, inverting the loose state back to a neat wound state
Solution Approach 2:
The patent recovers the consumable by rewinding it onto the spool after withdrawal, preventing loss of neatness and preparing it for stable reuse in printing operations
2Device complexity
If the consumable on the spool becomes loose, then the spool can be easily accessed, but jamming occurs during printing
Solution Approach 1:
The patent performs preliminary rewinding action after consumable withdrawal to maintain proper tension and neat distribution before the next printing operation, preventing jamming in advance
Solution Approach 2:
The spool serves itself by automatically rewinding the consumable through reverse rotation driven by the roller mechanism, maintaining its own proper state without external intervention
3Reliability
If a complex active power source system is used to rewind the consumable, then the rewinding function is reliable, but the device complexity increases
Solution Approach 1:
The system uses self-service by leveraging the existing roller mechanism and friction interaction to drive spool reverse rotation, eliminating the need for separate active power sources
Solution Approach 2:
The roller acts as an intermediary that transfers motion from the spool's natural unwinding to reverse rotation, mediating the rewinding process without requiring additional power sources
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively prevents jamming and maintains a neat distribution of consumables, ensuring stable operation of the 3D printing apparatus without the need for additional active power sources, relying on torsional or coil springs for rotation.
Implementation Method 1
the consumable spool is driven to rotate by an acting force between the roller and the consumable spool
Implementation Method 2
a driving assembly including a driving portion and a rotating shaft, the driving portion being connected to the rotating shaft for providing power to drive the rotating shaft to rotate

AI summary
A 3D printing apparatus includes a consumable spool for winding a consumable. A consumable rewinding device includes: a driving assembly including a driving portion and a rotating shaft, the driving portion being connected to the rotating shaft for providing power to drive the rotating shaft to rotate; and a roller for bearing a consumable spool, the rotating shaft is connected to the roller, and when the rotating shaft drives the roller to rotate, the consumable spool is driven to rotate by a frictional force between the roller and the consumable spool. The 3D printing apparatus and the consumable rewinding device enable the consumable to be rewound around the consumable spool, avoiding the problem of printer jamming due to messy distribution of the consumable, have a simple structure, and is easy to implement.
