Roll-off Film System Blade Section for Debris Removal
Solution Overview
Problem
Existing roll-off film systems for sport goggles are ineffective in preventing dirt and mud from entering the lens and canisters, which reduces the field of view and interferes with the rolling mechanism, necessitating an improved design to maintain clarity and functionality.
Innovation Solution
The roll-off film system includes film canisters with contact portions and blade sections that remove debris from the used film sections, directing it away from the lens field of view and preventing entry into the canisters, ensuring a clear and uninterrupted view for the user.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the roll-off film system conveys used film off the lens, then the field of view is maintained, but dirt or debris may enter through the interface between the film system and the lens, reducing the field of view
Solution Approach 1:
A waterproof adhesive film is applied to the interface between the roll-off film system and the lens, creating a flexible sealing barrier that prevents dirt and debris from entering through the interface while allowing the film system to function properly
Solution Approach 2:
The waterproof adhesive film acts as an intermediary sealing layer between the roll-off film system and the lens, mediating the interface to prevent harmful factors (dirt, debris) from penetrating through the gap
2Ease of operation
If the roll-off film system conveys used film into the canister, then the rolling mechanism functions, but dirt or mud may enter the canister and interfere with the rolling mechanism
Solution Approach 1:
A blade section is positioned at the canister opening to extract and remove dirt and debris from the used film section before it enters the canister, preventing contaminants from interfering with the rolling mechanism
Solution Approach 2:
The blade section converts the potentially harmful effect of dirt accumulation into a beneficial cleaning function, where the blade actively removes debris from the film as it is conveyed into the canister, ensuring continuous proper operation

AI summary
Roll-off film systems and methods are provided in accordance with one or more embodiments that may be installed on goggle frames or adaptors to goggle frames to provide improved field of vision for users. In particular, film canisters of the roll-off film systems may include a blade section configured to seamlessly contact the goggle frame or the adaptor to the goggle frame. Further, the blade section is configured remove mud or dirt from a used section of clear film when the used section is conveyed into the film canister to prevent excess mud or dirt from entering the film canister. The blade section also is configured to slant away from the lens of the goggle to allow the mud or dirt to fall away from the field of view on the lens to provide better field of view for the user.
