Goggle and Face Mask Pivot Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing protective gear for operators, such as welders, often requires cumbersome helmets that can be inconvenient to wear in certain environments, and there is a need for a solution that allows for flexible protection of both eyes and face without the necessity of a full helmet.
Innovation Solution
A goggle and face mask apparatus with a detachable pivot-connection and locking structure, allowing the goggle to be worn separately and easily assembled with a face mask, featuring a C-shaped receptacle and pin mechanism for pivotability and a fastening bolt system for secure locking, enabling quick and reliable face protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a full protective helmet is used to protect the operator's face, then facial protection is improved, but wearability and convenience deteriorate
Solution Approach 1:
The protective system is divided into separate components: a goggle for eye protection and a face mask for facial protection. These can be used independently or combined, allowing operators to choose the appropriate level of protection based on the working environment, thereby improving wearability while maintaining protection effectiveness.
Solution Approach 2:
The face mask is designed with a detachable and adjustable connection structure to the goggle, allowing dynamic configuration. The mask can be attached when full facial protection is needed and detached when less protection is required, enabling operators to adapt the protective gear to different operational conditions.
2Adaptability or versatility
If a detachable connection structure is provided between goggle and face mask, then adaptability is improved, but device complexity increases
Solution Approach 1:
The connection structure integrates multiple functions into a single mechanism: the detachable pivot connection provides both the attachment interface and the pivoting motion for mask adjustment. The locking structure combines securing and positioning functions, reducing the need for separate components and simplifying the overall design while maintaining adaptability.
Solution Approach 2:
The connection structure is designed to accommodate different configurations and adjustment needs through a universal interface. The pivot connection and locking mechanism can handle various mask positions and angles, providing multi-functionality that reduces the need for multiple specialized components.
3Reliability
If a locking structure is added to secure the face mask to goggle, then reliability is improved, but device complexity increases
Solution Approach 1:
The locking structure is designed to automatically engage and secure the face mask to the goggle through the pivoting and connection mechanism. The self-locking feature ensures reliable attachment without requiring additional fastening operations or complex control systems, maintaining simplicity while improving reliability.
4Ease of operation
If the face mask can be quickly assembled and disassembled, then ease of operation is improved, but connection reliability may deteriorate
Solution Approach 1:
The pivot connection enables quick assembly and disassembly through simple pivoting motion, while the locking structure ensures reliable connection when engaged. The dynamic design allows rapid adjustment and detachment without compromising connection stability during normal operation.
