Hearing Protector Spectacles Mounting Without Support Brackets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hearing protectors with integrated spectacles often require elaborate support brackets, limiting design simplicity and versatility.
Innovation Solution
The attachment of spectacles to the headband of the hearing protector is achieved through temples fastened to the headband, utilizing pivoting axes and mating parts, allowing independent movement and secure attachment without additional support brackets, with adjustable temple lengths and pivotable designs for enhanced fit and versatility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If support brackets are added to attach spectacles to ear protectors, then versatility is improved, but device complexity increases
Solution Approach 1:
The headband is designed to serve multiple functions: it supports the ear protectors and simultaneously provides attachment points for spectacles through integrated receptacles. This multi-functional design eliminates the need for separate support brackets, achieving versatility without increasing device complexity
Solution Approach 2:
The attachment mechanism for spectacles is merged into the headband structure itself. The receptacles are directly formed as part of the headband, combining the support and attachment functions into a single integrated component rather than using separate brackets
2Reliability
If additional support brackets are provided for spectacles, then attachment security is improved, but ease of manufacture deteriorates
Solution Approach 1:
The receptacles for spectacles are merged into the headband structure during the same manufacturing process. This integration means the headband is produced as a single component with built-in attachment features, eliminating the need for separate bracket manufacturing and assembly operations
Solution Approach 2:
The headband serves as both the primary support structure and the attachment mechanism for spectacles. This multi-functionality reduces the total number of parts that need to be manufactured and assembled, improving ease of manufacture while maintaining attachment security
