Soft Goggle Case with One-Handed Quick Release Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current protective cases for goggles, such as fabric drawstring bags, are inadequate for motocross and similar sports as they fail to protect goggles from debris, are difficult to open and close quickly, and do not provide convenient storage options, especially in dirty conditions.
Innovation Solution
A soft goggle case with a four-way stretch fabric and a quick, one-handed release mechanism featuring a T-shaped internal frame, a pivotable cover frame, and a release mechanism that includes a hook and pull cord, allowing for easy access and secure storage of goggles while preventing dust and debris from entering the case.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fabric drawstring bag is used to store goggles, then the goggles are protected from debris, but the case is difficult to open and close quickly and allows dust to enter during access
Solution Approach 1:
The patent applies a dynamic hinge mechanism that allows the case cover to rotate and open quickly with a single hand operation. The hinge enables smooth, rapid movement from closed to open position, transforming the static drawstring closure into a dynamic mechanical system that maintains protection while enabling fast access.
Solution Approach 2:
The case is segmented into a body portion and a removable cover portion connected by a hinge. This segmentation allows the cover to be independently manipulated for quick opening/closing while the body remains stationary and protected. The hinge creates a functional separation that enables rapid access without compromising the overall protective enclosure.
2Adaptability or versatility
If a fabric drawstring bag is used to store goggles, then the case is simple in structure, but it does not provide convenient storage options and is tricky to use in dirty conditions
Solution Approach 1:
The case design incorporates multiple functional elements: the hinge enables quick opening/closing, the elastic material provides stretchable protection, and the overall structure allows for various mounting options. This multi-functionality gives the case adaptability for different storage scenarios while maintaining a relatively simple overall structure.
Solution Approach 2:
The case utilizes elastic material that can stretch and conform to the goggles while maintaining protection. This flexible shell approach provides both protection and adaptability, allowing the case to accommodate different goggle shapes and sizes without requiring complex rigid structures.
3Loss of time
If goggles are stored in a drawstring bag, then they are protected from debris, but there is no easy or fast way to remove goggles without adding dust or fingerprints to the lens area
Solution Approach 1:
The hinge is pre-positioned to allow the cover to open in a controlled manner that exposes the goggles for immediate removal. The mechanical design anticipates the need for quick access by preparing the opening mechanism in advance, allowing the user to simply lift the cover and remove goggles without fumbling or exposing them to prolonged dust exposure.
Solution Approach 2:
The hinge mechanism extracts the cover portion from the body portion, creating a clear separation that allows the user to access goggles without reaching into a confined drawstring bag. This extraction of the cover creates an open pathway for quick goggle removal while keeping the body portion protected and stationary.

AI summary
A four-way stretch fabric case for storing a pair of goggles, the case having a hinged internal frame positioned inside a body portion and a cover portion. The internal frame is comprised of a cover frame sized and shaped to hingeably cover the body and further formed with a coupling point, a vertical leg and an open to load hinge affixed to both the cover frame and the vertical leg. A spring loaded release mechanism affixed to a lower end of the vertical leg is comprised of a post with a spring at its upper end and a hook at its lower end, with a release cord affixed to its lower end. The hook is adapted to disengage the coupling point by pulling the cord and moving the hook to allow the cover to hinge open.
