Flip-Down Film Applicator Structure for Low-Height Packaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing film applicators increase packaging height and costs due to uneven structures, leading to inconsistent packaging and higher export costs when the height exceeds standards.
Innovation Solution
A film applicator design with a sliding and rotatable installation bracket that flips relative to the base, allowing it to align with or be lower than the base during packaging, reducing overall height and preventing uneven packaging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a scraper and support structure are provided on the base to prevent bubbles, then film adhesion quality is improved, but the height of the film applicator increases
Solution Approach 1:
The installation bracket is designed to be rotatable relative to the base, allowing it to change position from a horizontal state (during operation) to a vertical state (during packaging). This dynamic reconfiguration enables the structure to adapt to different functional requirements: providing scraping support during film application, and minimizing height during packaging.
Solution Approach 2:
The installation bracket utilizes rotational movement to transition between dimensional configurations. When rotated to the vertical position, the bracket's height component is minimized along the packaging direction, effectively reducing the overall height of the film applicator while maintaining the scraping functionality when in the horizontal position.
2Reliability
If the height of the film applicator increases due to support structures, then bubble prevention capability is improved, but packaging costs increase
Solution Approach 1:
The rotatable installation bracket allows the system to dynamically adjust its configuration based on operational needs. During packaging, the bracket is rotated to a vertical position where it no longer contributes to the overall height, thereby avoiding increased packaging costs while maintaining bubble prevention capability during actual film application.
3Ease of operation
If the installation bracket is fixed in a horizontal position, then scraping function is improved, but packaging uniformity deteriorates
Solution Approach 1:
The installation bracket is designed with rotational capability around a vertical axis, allowing it to switch between a horizontal position (optimizing scraping function during operation) and a vertical position (optimizing packaging uniformity by reducing height variation). This dynamic reconfiguration resolves the contradiction between operational effectiveness and packaging consistency.
Solution Approach 2:
Instead of fixing the installation bracket in a horizontal position that optimizes scraping but worsens packaging, the design allows the bracket to be inverted or rotated to a vertical position during packaging. This inversion enables the system to prioritize packaging uniformity when needed, while maintaining scraping optimization during operation.

AI summary
A film applicator that is convenient for packaging is provided, which includes a base, and the base is provided with a receiving groove, a first sliding element and a first connector, the first connector is located at an end of the base; a film sticking component including an installation bracket and a pressing film component, the installation bracket is provided with a second sliding element and a second connector. The second sliding element is slidably fitted with the first sliding element to guide the installation bracket to move back and forth along a film lamination direction. The second connector is connected and rotatably fitted with the first connector when the installation bracket slides to the end of the base, so that the installation bracket can be flipped relative to the base and aligned with or lower than an end face of the base, which is convenient to package.
