Wearable Display Bridge Protrusion for Structural Integrity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable display devices face challenges in maintaining sufficient strength while reducing the size of the bridge portion, which can lead to distortion and deformation, particularly in the notch portion and central area.
Innovation Solution
Incorporating a protruding portion on the coupling member that extends in the lateral direction to align and couple the first and second optical members, providing reinforcement and allowing for the attachment of a nose pad, thus maintaining strength and reducing size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the bridge portion is reduced in size to make the wearable display device more compact, then the overall device size is reduced, but the strength and structural integrity of the bridge portion and notch area deteriorate, causing distortion and deformation
Solution Approach 1:
The coupling member is divided into multiple functional regions: a main body portion for coupling the optical members, a protruding portion extending laterally for structural reinforcement, and a nose pad attachment portion. This segmentation allows each region to perform its specific function optimally while maintaining overall compactness.
Solution Approach 2:
The protruding portion is strategically positioned and dimensioned to provide localized reinforcement exactly where needed in the bridge area. By concentrating material and structural support in this specific region rather than uniformly throughout the entire bridge portion, the design achieves enhanced strength at critical locations while keeping the overall device size reduced.
2Volume of moving object
If the bridge portion is reduced in size, then the device becomes more compact, but the structural integrity and resistance to distortion in the central area deteriorate
Solution Approach 1:
The protruding portion extends in the lateral direction (width dimension) rather than only in the vertical or depth directions. This dimensional approach allows the bridge portion to gain structural stability through lateral reinforcement, effectively distributing stresses and preventing distortion without increasing the overall device volume significantly.
Solution Approach 2:
The coupling member appears to be designed as an integrated composite structure combining the main body, protruding portion, and nose pad attachment features into a single unified component. This composite design allows different regions to have optimized properties for their specific functions while maintaining overall structural integrity through the integrated construction.
3Volume of moving object
If the bridge portion is reduced in size, then the device is more compact, but the ability to maintain sufficient strength in the notch portion deteriorates
Solution Approach 1:
The protruding portion is pre-positioned and integrated into the coupling member design before final assembly. This preliminary structural reinforcement is built into the bridge portion itself, proactively preventing potential weakness points in the notch area before they can cause failure, rather than attempting to reinforce the area after the fact.
Solution Approach 2:
The protruding portion acts as an intermediary structural element between the main body of the coupling member and the notch area. It serves as a mediator that transfers and distributes mechanical loads away from the vulnerable notch region, protecting it from stress concentration and potential failure while maintaining the compact overall design.
