Solution Overview

Problem

Traditional multimedia interaction systems fail to ensure that multimedia interactions conform to normal user experiences due to the inability to determine the relative position of electronic devices, leading to unexpected interactions where signals are transmitted or received in unintended directions.

Innovation Solution

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If electronic devices are designed to transmit/receive signals in various directions to acquire better signal transmission quality, then signal transmission ability is improved, but unexpected interactions occur where signals are transmitted to unintended directions

Engineering Contradiction:

Improvesignal transmission qualityVSAvoidunexpected interaction behavior

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent applies dynamics by making the signal transmission direction adjustable and adaptive rather than fixed. The system dynamically determines transmission directions based on real-time spatial positions of electronic devices, allowing the transmission pattern to change according to operational conditions. This resolves the contradiction by enabling multi-directional transmission capability while preventing unintended signal transmission through dynamic directional control.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent implements feedback mechanisms where the system continuously monitors the spatial positions of electronic devices and uses this information to adjust signal transmission directions. The position detection results feed back to the control system, which then determines appropriate transmission directions. This closed-loop feedback prevents unexpected interactions by ensuring signals are only transmitted toward intended targets based on their current positions.

Inventive Principle:

Principle #23Feedback

2Measurement precision

If the system restricts signal transmission to specific directions to avoid unexpected interactions, then interaction accuracy is improved, but signal transmission ability and receiving range are severely influenced

Engineering Contradiction:

Improveinteraction accuracyVSAvoidsignal transmission ability

Core Design Contradiction:

Measurement precisionVSAdaptability or versatility

Solution Approach 1:

The patent applies universality by designing a system that can perform multiple functions: it can transmit signals in various directions when needed while maintaining the ability to restrict transmission to specific directions when required. The position detection circuit and control system enable the same transmission system to adaptively change its behavior based on operational requirements, achieving both high interaction accuracy and preserved signal transmission ability.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent changes the parameter of transmission direction from fixed to variable. By detecting spatial positions and using this information to dynamically adjust transmission directions, the system maintains high interaction accuracy while preserving signal transmission ability. The transmission parameters are modified based on detected position data, allowing the system to optimize between accuracy and versatility as needed.

Inventive Principle:

Principle #35Parameter changes

3Device complexity

If the system does not detect relative positions of electronic devices, then device complexity is reduced, but multimedia interaction results do not conform to normal user experiences

Engineering Contradiction:

Improvesystem simplicityVSAvoiduser experience conformity

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The patent introduces a position detection circuit as an intermediary component that bridges the gap between simple device architecture and reliable user experience. This intermediary detects spatial positions of electronic devices and provides this information to the control system, enabling experience-conforming interactions without significantly increasing overall system complexity. The detection circuit acts as a mediator that enables intelligent behavior with minimal added complexity.

AI summary

A multimedia interaction system includes: multiple electronic devices and a location detection circuit. The location detection circuit dynamically detects respective electronic device's spatial position and orientation. When an user instructs a source electronic device of the multiple electronic devices to transmit a target image object toward a selected direction, the source electronic device decides a target direction according to a location of a first candidate electronic device and the selected direction if a relative position between the first candidate electronic and the selected direction satisfies a first predetermined condition. The source electronic device transmits a target command corresponding to the target image object to a second candidate electronic device to perform corresponding multimedia interaction operations only if a relative position between the second candidate electronic and the target direction satisfies a second predetermined condition.
