Solution Overview
Problem
Conventional film packing devices are cumbersome, cause back pain, and result in inconsistent film application and damage, especially when handling rolls with or without reels, and are not adaptable to different types of film application units.
Innovation Solution
A film packing device with a handle and quick-release mechanism, featuring a coupling rod with elastic members and a roller unit with adjustable gear ratios, allowing for easy mounting and replacement of film rolls with or without reels, providing consistent and adjustable tension for secure packing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional film packing devices use manual bending and pulling methods, then the device structure remains simple, but it causes back pain, unsafe situations, and inconsistent film application
Solution Approach 1:
The device is divided into distinct functional modules: a handle assembly, a film application unit with roller, and a mounting mechanism. This segmentation allows each component to perform its specific function efficiently while maintaining overall system simplicity, resolving the contradiction between operational safety and structural complexity
Solution Approach 2:
The elastic member automatically engages with the positioning portion to secure the film roll, and the gear mechanism automatically adjusts film tension during application. This self-service mechanism eliminates the need for manual intervention in tension control, improving operational consistency without adding complex control systems
2Adaptability or versatility
If the film packing device is designed for specific film application units only, then the device structure can be simplified, but it requires multiple devices for different film types
Solution Approach 1:
The mounting mechanism features a universal interface with a positioning portion that can accommodate different film application unit types. The elastic member and retaining structure are designed to work with various film roll configurations (with or without reels), allowing one device to serve multiple functions and eliminating the need for multiple specialized devices
Solution Approach 2:
The mounting mechanism incorporates movable components that can adapt their position and configuration based on the specific film application unit being installed. This dynamic adjustment capability enables the same mounting structure to securely hold different film types without requiring multiple fixed designs
3Manufacturing precision
If manual film application is used, then the device remains simple, but it results in inconsistent film application and load stabilization
Solution Approach 1:
The gear mechanism provides automatic feedback control for film tension. As the roller rotates during film application, the gear system automatically adjusts the pull force to maintain consistent tension, eliminating the variability inherent in manual application while keeping the mechanism relatively simple through mechanical self-regulation

AI summary
A film packing device (100) for a roll of film having or not having a reel includes a handle (10). Two ends of the handle (10) are provided with a coupling rod (11) and a base (12), respectively. The coupling rod (11) is provided with a quick-release unit (14). The base (12) is provided with a limit unit (15). The quick-release unit (14) and the limit unit (15) are selectively mounted with a first film application unit (40) and a second film application unit (30). Through the first film application unit (40), the film packing device (100) can be mounted with a roll of film having a paper reel. Through the second film application unit (30), the film packing device (100) can be mounted with a roll of film not having a paper reel. The film packing device (100) can be replaced with different types of film in a simple and quick way.
