Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current head-wearable display devices face challenges in prolonged usage due to limited battery capacity in portable terminals, external power supply interfaces affecting aesthetics and increasing costs, and heat issues with large-capacity batteries.
Innovation Solution
A head-wearable displaying and powering system that includes a powering device with two communication interfaces connecting the portable terminal and head-wearable display device, allowing direct data communication and power supply without consuming the portable terminal's battery, and enabling the powering device to charge both devices independently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If a large-capacity battery is provided in the head-wearable display device, then the usage duration is extended, but the device generates heat and may cause superheat or safety issues
Solution Approach 1:
The patent extracts the large-capacity battery from the head-wearable display device and places it in a separate portable terminal. This removes the heat-generating component from the head-wearable device while maintaining the ability to extend usage duration through wireless power transfer.
Solution Approach 2:
The patent introduces wireless power transfer technology as an intermediary mechanism between the portable terminal's battery and the head-wearable display device. This allows power to be transmitted without physical contact or heat transfer, solving both the duration extension need and the heat generation problem.
2Duration of action of moving object
If an external power supply interface or power line is provided on the head-wearable display device, then the device can be powered externally, but the product appearance is compromised and costs increase
Solution Approach 1:
The patent replaces the mechanical power supply interface (physical cable connection) with a wireless power transfer system. This eliminates the need for visible ports or cables on the head-wearable device, preserving its aesthetic appearance while maintaining external power supply capability.
3Device complexity
If the portable terminal's battery is used to power the head-wearable display device, then the system is simple, but the battery capacity is insufficient for long-duration use
Solution Approach 1:
The patent makes the portable terminal's battery serve multiple functions: it powers both the portable terminal itself and the head-wearable display device through wireless power transfer. This multi-functionality allows the existing battery to support extended usage without requiring additional battery capacity in the head-wearable device.
