Solution Overview
Problem
Conventional film packing devices are cumbersome, unsafe, and inefficient, causing back pain and inconsistent film application, especially when handling rolls with or without reels, and require separate devices for different types of film application units.
Innovation Solution
A film packing device with a handle and dual film application units, featuring a quick-release mechanism with elastic and retaining members, and a roller unit with adjustable gear ratios for consistent and reproducible film application, allowing easy switching between rolls with and without reels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If manual film application is used, then the device structure is simple, but the operation safety deteriorates and causes back pain
Solution Approach 1:
The film application system is segmented into modular components: a reusable handle assembly and interchangeable film application units (first for reels, second for coreless film). This allows the complex mechanical handling to be separated from the simple manual operation, improving safety while maintaining structural simplicity through modularity.
Solution Approach 2:
The film application units are designed to be self-contained with integrated film rolls, eliminating the need for manual film handling and application. The units automatically apply film through their mechanical design, reducing physical strain and improving operator safety.
2Manufacturing precision
If separate devices are prepared for different film application units, then the film application precision is improved, but the device complexity increases
Solution Approach 1:
The handle assembly is designed as a universal base that can accommodate both the first film application unit (for reels) and the second film application unit (for coreless film). The handle includes a mounting structure that universally accepts different film application units, allowing one device to perform multiple functions with different film types.
Solution Approach 2:
The device transitions from a static, single-purpose design to a dynamic, multi-configurable system. The handle assembly can be quickly reconfigured by swapping film application units, allowing the same base device to adapt to different film types and application requirements, maintaining precision while reducing overall device variety.
3Device complexity
If manual film pulling is used, then the device structure is simple, but the film application consistency deteriorates
Solution Approach 1:
The film application process is segmented into controlled mechanical stages within the film application units. The film path, tensioning, and application points are mechanically defined rather than manually controlled, ensuring consistent application while keeping the overall device structure relatively simple through modular design.
Solution Approach 2:
Manual mechanical pulling and positioning is replaced with engineered mechanical systems within the film application units. These include guided film paths, tensioning mechanisms, and positioned rollers that mechanically ensure consistent film application, replacing variable human effort with reliable mechanical control.
4Adaptability or versatility
If quick-release unit is added, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The quick-release mechanism is segmented into discrete mounting and dismounting components integrated into the handle assembly. The retaining member, elastic member, and limiting member are separate elements that work together to provide quick attachment/detachment functionality without requiring a completely complex locking system.
Solution Approach 2:
The quick-release unit acts as an intermediary mechanism between the handle assembly and the film application units. It provides a standardized interface that simplifies the connection process, allowing different film application units to be quickly attached and detached from the same handle without direct complex interfacing.

AI summary
A film packing device for a roll of film having or not having a reel includes a handle. Two ends of the handle are provided with a coupling rod and a base, respectively. The coupling rod is provided with a quick-release unit. The base is provided with a limit unit. The quick-release unit and the limit unit are selectively mounted with a first film application unit and a second film application unit. Through the first film application unit, the film packing device can be mounted with a roll of film having a paper reel. Through the second film application unit, the film packing device can be mounted with a roll of film not having a paper reel. The film packing device can be replaced with different types of film in a simple and quick way.
