Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile devices, such as smartwatches, are limited by their small size, which restricts the placement and efficiency of multiple antennas, leading to compromised wireless performance due to space constraints and metal enclosures, and they fail to adapt to individual user interactions and environments.
Innovation Solution
The system dynamically tunes wireless antennas based on contextual information, using AI and ML to adjust antenna operational parameters, such as beam steering and radiation patterns, in real-time, to optimize performance for the user's specific environment and usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple antennas are placed in a small mobile device, then wireless communication capability is improved, but space constraints and metal enclosures compromise antenna efficiency and performance
Solution Approach 1:
The patent implements dynamic antenna tuning by continuously monitoring contextual information (touch inputs, environmental data, usage patterns) and adjusting antenna operational parameters in real-time. This dynamic adaptation allows the antenna system to optimize its performance for different scenarios, effectively resolving the contradiction between maintaining high wireless capability and achieving reliable antenna efficiency in constrained spaces.
Solution Approach 2:
The system changes antenna operational parameters (such as impedance, resonance frequency, and radiation patterns) based on contextual conditions. By dynamically adjusting these parameters rather than using fixed configurations, the antenna maintains high efficiency across diverse operating conditions despite physical constraints from the small device form factor and metal enclosure.
2Reliability
If antenna operational parameters are dynamically adjusted based on contextual information, then wireless performance is optimized for specific environments, but device complexity increases
Solution Approach 1:
The antenna system monitors its own operational context (touch inputs, environmental conditions, usage patterns) and automatically adjusts its parameters without requiring external intervention or complex control systems. This self-service capability allows the system to optimize performance while minimizing the complexity of additional hardware and control logic that would be needed for manual or externally-controlled tuning.
3Volume of moving object
If device size is reduced, then portability is improved, but antenna placement and efficiency are compromised
Solution Approach 1:
By dynamically changing antenna operational parameters based on contextual information, the system compensates for the physical constraints imposed by the small device form factor. This allows the antenna to maintain optimal efficiency despite limited space for placement and the presence of metal enclosures that can interfere with radiation patterns.

AI summary
The disclosed computer-implemented method may include accessing various portions of contextual information based on at least one touch input from a touch-based sensor on a mobile electronic device. The method may next include determining, based on the contextual information, which of different operational antenna parameters associated with at least one antenna of the mobile electronic device are to be changed. The method may then include changing the specified operational parameters associated with the antenna on the mobile electronic device according to the determination. Various other methods, systems, and computer-readable media are also disclosed.
