Mobile Cart Cable Management for VR and Audio Applications
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile platforms are not suitable for virtual reality and multi-participant experiences, DJ configurations, and karaoke applications due to inadequate cable management and equipment recalibration issues, particularly with head-mounted displays and positional sensors.
Innovation Solution
A mobile cart with tensioned tethers for cable management, rigid vertical supports for equipment stability, and customizable storage compartments with power supply options, along with adjustable boom arms for equipment mounting, to prevent user interference and recalibration needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If cables are routed loosely for user accessibility, then ease of operation is improved, but cable entanglement and user interference increase
Solution Approach 1:
A cable management system with tensioning devices and guide structures acts as an intermediary between the cable and the user environment. The system includes cable guides mounted on the cart frame and tensioning devices that maintain proper cable routing, preventing entanglement while preserving user accessibility to audio equipment.
2Adaptability or versatility
If positional sensors are made movable for flexibility, then adaptability is improved, but measurement precision deteriorates due to recalibration needs
Solution Approach 1:
The cart structure is segmented into fixed mounting areas and movable equipment areas. Positional sensors are mounted on rigid, fixed portions of the cart frame to maintain calibration accuracy, while other equipment that requires flexibility is positioned on movable components or adjustable mounts.
3Reliability
If the cart structure is made rigid for stability, then reliability is improved, but device complexity increases
Solution Approach 1:
The cart employs selective rigidity where rigid structural components are used only in critical areas requiring stability (such as the main frame and sensor mounting points), while other areas utilize lighter, more flexible materials or components. This localized approach to structural quality maintains reliability where needed without unnecessarily increasing overall complexity.

AI summary
A mobile cart for use in virtual reality and monitor-based multi-participant experiences, DJ configurations, karaoke and audio uses incorporating vertical supports extending from the housing, supporting fixed, pivotal or rotative booms radially extending from the housing serving as supports for equipment such as microphones, positional sensors, head mounted displays, and retractable tethers performing cable management by holding one or more equipment cables above a user's head to prevent user cable-entanglement, such as, when using head mounted displays.
