Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional electronic devices often fail to cooperate to produce coordinated outputs and do not account for their relative positions and orientations, which can negatively impact the quality of the output.
Innovation Solution
Electronic devices equipped with antennas to detect wireless signal pulses, such as UWB signals, determine spatial parameters like distances and orientations, and process these to provide coordinated graphical or audio outputs by adjusting partial outputs based on these parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple electronic devices cooperate to produce coordinated outputs, then the quality of multi-channel audio and multi-display experiences is improved, but the device complexity increases
Solution Approach 1:
The patent replaces complex mechanical coordination systems with wireless communication and software-based spatial parameter analysis. Devices use wireless signal pulses to exchange localization data and coordinate their outputs through software processing, eliminating the need for physical connection mechanisms and reducing system complexity while maintaining coordination quality.
Solution Approach 2:
The patent introduces wireless signal pulses as an intermediary medium that carries spatial parameter information between devices. This intermediary enables devices to determine their relative positions and orientations without direct physical contact or complex control systems, simplifying the coordination mechanism while improving output quality.
2Adaptability or versatility
If devices account for their relative positions and orientations, then the adaptability of the output is improved, but the measurement precision requirements increase
Solution Approach 1:
The patent uses wireless signal pulses to create a digital copy or representation of the physical spatial relationships between devices. By analyzing the characteristics of these signal pulses, devices can determine their relative positions and orientations without requiring direct physical measurement, reducing the precision requirements of physical sensors while maintaining high adaptability.
Solution Approach 2:
The patent transforms physical spatial parameters (position, orientation) into measurable signal characteristics through wireless communication. By changing the measurement domain from direct physical measurement to signal analysis, the system achieves high adaptability with reduced measurement precision requirements, as signal processing can extract spatial information with sufficient accuracy.

AI summary
Device localization (e.g., ultra-wideband device localization) may be used to provide coordinated outputs and/or receive coordinated inputs using multiple devices. Providing coordinated outputs may include providing partial outputs using multiple devices, modifying an output of a device based on its position and/or orientation relative to another device, and the like. In some cases, each device of a set of multiple devices may provide a partial output, which combines with partial outputs of the remaining devices to produce a coordinated output.
