Integrated Ear and Eye Protector with Adjustable Sound Dampening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing safety equipment for protecting sight and hearing often requires separate devices and can be cumbersome, lacking in practicality and comfort, especially in environments where both eye and ear protection are mandatory.
Innovation Solution
A combined ear and eye protection apparatus featuring ear muff style ear protectors connected to a resilient eye protector assembly, allowing for adjustable positioning and independent operation of ear protectors to enable temporary reduction in sound protection, with features like swing couplings, apertures, and adjustable mountings for enhanced usability and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate eye protection and ear protection devices are used, then each device can provide dedicated protection, but the equipment becomes cumbersome and uncomfortable to wear
Solution Approach 1:
The patent combines separate eye protection (visor) and ear protection (ear muffs) into a single integrated safety device. The visor is structurally connected to the ear protectors through mounting points, allowing both protection functions to be worn simultaneously as one unified apparatus, thereby improving comfort and reducing the burden of wearing multiple separate devices.
Solution Approach 2:
The integrated device serves multiple protective functions simultaneously - the visor provides eye protection while the ear protectors provide hearing protection. This multi-functional design allows a single device to replace what would traditionally require separate equipment, addressing the contradiction between comprehensive protection and wearability comfort.
2Reliability
If continuous sound protection is maintained, then hearing protection is maximized, but the wearer cannot hear external sounds clearly when needed
Solution Approach 1:
The ear protectors are designed with dynamic adjustability, allowing the wearer to modify the level of sound protection as needed. This enables the device to adapt between providing maximum hearing protection and allowing external sounds to be heard more clearly, resolving the contradiction between continuous protection and situational adaptability.
Solution Approach 2:
The sound protection parameter can be changed by the wearer through adjustable mechanisms in the ear protectors. This allows modification of the acoustic properties to transition between closed (maximum protection) and open (clearer external sound) states, providing the needed versatility while maintaining protection effectiveness.
3Stability of the object's composition
If the visor is rigidly fixed to provide stable eye protection, then eye protection stability is maximized, but the device cannot adapt to different wearing positions and becomes less comfortable
Solution Approach 1:
The connection between the visor and ear protectors incorporates resilient or adjustable mounting mechanisms that allow the visor to move between different positions. This dynamic connection enables the visor to adapt to various wearing positions (resting on the face or elevated) while maintaining stable eye protection, resolving the contradiction between stability and flexibility.
Solution Approach 2:
The positioning parameters of the visor can be changed to accommodate different wearing preferences and head positions. The resilient mounting allows adjustment of the visor's position and angle while maintaining secure attachment, providing both stability for protection and adaptability for comfort.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The apparatus provides effective and comfortable protection for both eyes and ears, allowing for easy adjustment and temporary reduction in sound protection, enhancing practicality and reducing the likelihood of equipment misplacement or discomfort, thus encouraging consistent use in various work environments.
Implementation Method 1
the assembly of the arms and eye protector is resiliently formed such that, when worn, the resilience of the assembly urges the arms and respective ear protectors inwardly to grip the wearer's head and support the apparatus in place

AI summary
An ear muff style ear protector device having a body for permitting positioning on a wearer's head, and two ear muff ear protectors connected with the body, so the ear protectors can be operatively held relative to a wearer's ears. At least one ear protector can be adapted to selectively enable the wearer to temporarily reduce the level of sound protection to the respective ear to enable external sounds to be heard more clearly. In an embodiment the body is an eye protector assembly, which is connected to the two ear muff ear protectors.
