Noise Reduction Goggles With Retractable Earplug Pendants
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing protective equipment, such as separate earplugs and goggles, are inconvenient to store, aesthetically unpleasing, and pose safety hazards due to connecting ropes, while failing to provide comprehensive protection in high-noise and debris environments.
Innovation Solution
Integrated noise reduction goggles with hinged legs, adjustable noise reduction pendants, and automatic adjustment mechanisms for earplugs, allowing easy extension and retraction, and a detachable design for safe storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate earplugs are used, then noise reduction function is provided, but storage convenience deteriorates and loss risk increases
Solution Approach 1:
The patent combines separate earplugs and goggles into an integrated protective equipment system. The earplugs are attached to the goggles via a connecting structure, allowing both eye and ear protection to be worn as a single unit. This merging eliminates the need to carry separate earplugs, improves storage convenience, and reduces the risk of loss while maintaining the noise reduction function.
2Reliability
If connecting ropes are used to fix earplugs, then earplugs are prevented from dropping, but aesthetic appearance deteriorates and safety hazards increase
Solution Approach 1:
The connecting structure integrates the earplugs with the goggles in a unified design, eliminating loose connecting ropes. The earplugs are attached directly to the goggles frame through a structured connection mechanism, which prevents dropping while avoiding the aesthetic and safety issues of dangling ropes.
Solution Approach 2:
The patent removes the problematic rope body from the connecting structure. Instead of using visible connecting ropes that swing behind the ears, the design extracts this element and replaces it with a integrated attachment mechanism that maintains earplug retention without creating safety hazards.
3Ease of operation
If integrated noise reduction goggles are designed, then convenience and aesthetics are improved, but device complexity increases
Solution Approach 1:
The patent merges earplugs and goggles into a single integrated unit, which simplifies the user experience by eliminating the need to manage separate protective items. Although the integration adds some structural complexity, it reduces overall system complexity from the user's perspective by consolidating multiple functions into one device.

AI summary
Noise reduction goggles are provided, which relate to the technical field of protective equipment. The noise reduction goggles include a goggles frame and goggles legs; noise reduction pendants are mounted at the goggles legs; each noise reduction pendant is provided with an adjustment mechanism, a cotton thread, and a noise reduction earplug; the cotton thread is connected to the adjustment mechanism and the noise reduction earplug; and the adjustment mechanisms adjust lengths of the cotton threads, to release or withdraw the noise reduction earplugs. In summary, by efficient integration of the goggles and the noise reduction earplugs, one-key return, and automatic positioning, a user experience and operation convenience are improved, and stability and safety of equipment are ensured.
