Solution Overview
Problem
Current VR/AR devices are limited by their monolithic design, leading to issues with size, weight, battery life, and upgradeability, as well as restricted functionality and mobility due to integrated subsystems and battery constraints.
Innovation Solution
A modular headphone-based VR/AR platform with interchangeable 'pucks' that include various components such as light field capture, audio and video receptors, projectors, and processing units, allowing for flexible configuration and upgrade without replacing the entire device, and a drone-based recharging system for extended battery life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If VR/AR devices include more functionality and integrated subsystems, then the immersive experience is improved, but the device becomes heavy and cumbersome
Solution Approach 1:
The VR/AR device is divided into separate modular components: a head-mounted display unit and removable battery packs. This segmentation allows the battery to be replaced independently from the main device, enabling users to carry multiple battery packs to extend usage time without increasing the weight of the head-mounted portion.
Solution Approach 2:
The solution moves the battery weight from the head-mounted dimension to an external carrying dimension. Users wear the lightweight display on their head while carrying multiple battery packs in pockets or bags, redistributing weight across different body dimensions and solving the weight-constraint problem.
2Reliability
If VR/AR devices are designed as monolithic integrated units, then system reliability is improved, but upgradeability and customization are restricted
Solution Approach 1:
The device architecture separates the permanent head-mounted display unit from replaceable battery packs with standardized interfaces. This segmentation maintains system reliability through standardized connections while enabling easy upgrades by replacing individual battery packs with newer models or different capacity batteries.
Solution Approach 2:
The standardized battery interface creates a universal system where a single head-mounted display can work with multiple battery pack variants. This universality allows users to upgrade batteries independently and customize their device based on different usage scenarios without replacing the entire system.
3Duration of action of moving object
If battery capacity is increased to extend usage time, then duration of action is improved, but device size and weight increase
Solution Approach 1:
The battery system is segmented into removable packs that can be carried separately from the head-mounted display. Users can carry multiple standard-sized battery packs to achieve extended total usage time without increasing the size or weight of the worn device portion.
Solution Approach 2:
The solution transitions from extending battery life within the constrained head-mounted volume to distributing battery capacity across multiple externally carried packs. This dimensional shift allows users to achieve 24+ hours of total usage by carrying multiple packs without compromising the comfort or size of the worn device.
4Device complexity
If integrated subsystems are used in VR/AR devices, then device complexity is reduced, but mobility and battery life are restricted
Solution Approach 1:
The system segments the battery function from the integrated head-mounted subsystems. The display, sensors, and processing remain integrated for simplicity, while the power system is separated into replaceable packs. This allows maintained system integration where it matters for performance while gaining battery flexibility.
