Solution Overview
Problem
Current display technologies do not effectively create the aesthetic illusion of a display device floating in space, failing to combine artistic design with functional technology to meet the demands of the Artygen consumer group.
Innovation Solution
A display device comprising a panel unit and a frame unit spaced apart by a transparent support, with wireless power transmission between them, allowing the panel unit to appear as if it is floating, using bar-shaped resonators and multiple power receivers/transmitters for efficient power delivery and alignment compensation, and enabling independent operation of the frame unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the panel unit and frame unit are spaced apart to create a floating appearance, then aesthetic appeal is improved, but structural stability deteriorates
Solution Approach 1:
A transparent support structure acts as an intermediary between the panel unit and frame unit, maintaining the spaced-apart configuration for aesthetic purposes while providing the necessary structural stability. The transparent support is invisible or minimally visible, preserving the floating appearance while mechanically connecting the components.
2Shape
If wireless power transmission is implemented between spaced units, then aesthetic appeal is improved, but power transmission efficiency deteriorates
Solution Approach 1:
Wireless power transmission technology replaces traditional wired power connection, eliminating the need for physical cables between the frame unit and panel unit. This substitution enables the spaced-apart configuration for aesthetic purposes while maintaining power supply functionality, despite the inherent energy loss in wireless transmission.
3Reliability
If multiple power receivers and transmitters are used for alignment compensation, then power transmission reliability is improved, but device complexity increases
Solution Approach 1:
The power transmission system is segmented into multiple independent power transmitter-receiver pairs distributed around the perimeter of the display device. This segmentation allows each pair to operate independently and compensates for misalignment issues, as at least one pair can maintain effective power transmission even when others are misaligned.
Solution Approach 2:
The system changes the spatial parameters of power transmission by distributing multiple transmitter-receiver pairs at different locations and orientations. This parameter change enables the system to adapt to alignment variations and maintain reliable power transmission under different operational conditions.
