Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current virtual reality glasses require manual adjustment of the headband tightness by users, which can be inconvenient, especially for individuals with hand disabilities, necessitating assistance and reducing user experience.
Innovation Solution
The virtual reality glasses incorporate a headband with a pressure detection device and a drive mechanism controlled by a control device, allowing for autonomous adjustment of the headband tension based on detected pressure, enabling self-adjustment and improved usability for users with disabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual adjustment of headband tightness is required, then the device structure remains simple, but the ease of operation deteriorates especially for users with hand disabilities
Solution Approach 1:
The system enables self-adjustment through automatic pressure detection and drive-controlled headband tensioning. The pressure detection device monitors head pressure, and the drive device automatically adjusts the headband tightness without requiring manual user intervention, allowing users with hand disabilities to wear the glasses independently.
Solution Approach 2:
The manual mechanical adjustment operation is replaced with an automated electromechanical system. The pressure detection device senses head pressure, the control device processes the signal, and the drive device actuates the headband adjustment mechanism, substituting manual mechanical operation with an automated control system.
2Extent of automation
If automatic pressure detection and adjustment is implemented, then the ease of operation improves for users with disabilities, but the device complexity increases
Solution Approach 1:
The system implements a closed-loop feedback control mechanism. The pressure detection device continuously monitors the pressure applied by the headband on the user's head, sends signals to the control device, which then adjusts the drive device to maintain optimal pressure. This feedback loop enables automatic adaptation to different users and wearing conditions.
Solution Approach 2:
The control device serves multiple functions: it receives pressure detection signals, processes adjustment commands, controls the drive device, and maintains optimal headband tension. This multi-functionality reduces the need for separate dedicated components for each function, thereby managing system complexity while achieving automation.
