Wearable Display Sliding Hinge Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable display devices face issues with malfunctioning and damage when used for extended periods, and they obstruct the user's field of vision when not in use, while also being vulnerable to dust and moisture due to exposed interfaces.
Innovation Solution
A wearable display device design featuring a sliding display unit with a hinge that can be bent, allowing the interface to be hidden when not in use, and automatically bending to avoid obstruction or damage detection, with a camera and sensor system for safety features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display unit is fixed to the frame, then the device structure is simple, but the display unit obstructs the user's field of vision when not in use
Solution Approach 1:
The display unit is made movable through a sliding mechanism that allows it to move between a first position (blocking vision) and a second position (not blocking vision). The sliding element enables the display unit to dynamically adjust its position based on usage requirements, resolving the contradiction between maintaining a simple fixed structure and enabling dynamic repositioning to clear the field of vision.
2Ease of operation
If the interface unit is exposed to the exterior, then the user can easily access controls, but the device becomes vulnerable to damage from dust and moisture
Solution Approach 1:
The interface unit's accessibility is dynamically controlled through the sliding mechanism. When the display unit slides to the first position, the interface unit becomes accessible to the user. When the display unit slides to the second position, the interface unit is protected from environmental factors. This dynamic repositioning resolves the contradiction between ease of access and protection from harmful factors.
3Reliability
If the display unit is always positioned to show images, then the user can continuously view information, but the device is susceptible to damage from extended exposure
Solution Approach 1:
The sliding mechanism enables periodic repositioning of the display unit between two positions. The display unit can be positioned in the first state for information display and then moved to the second state for protection and rest. This periodic action between usage and protection states resolves the contradiction between continuous information display and device durability by introducing scheduled intervals for protective positioning.
