Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G communication systems, the challenge is to enhance antenna performance in compact electronic devices, such as smartphones, where space constraints limit antenna size, leading to reduced performance, especially when the device is used in various orientations or with a user's handgrip, affecting resonance frequency and data transmission rates.
Innovation Solution
An assist device with a second antenna that generates capacitance with the internal antenna of the electronic device, allowing for adjustable capacitance based on the relative position relationship, thereby improving antenna performance and resonance frequency across different usage statuses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the antenna size is reduced to fit compact electronic devices, then the device size is decreased, but the antenna performance is deteriorated
Solution Approach 1:
The assist device acts as an intermediary between the user's handgrip and the internal antenna. By placing the second antenna on the assist device rather than inside the electronic device, the patent creates a separate element that can compensate for handgrip effects without occupying space within the compact device body.
Solution Approach 2:
The patent moves the antenna function from a single internal element to a multi-dimensional system involving both the internal antenna and the second antenna on the assist device. This spatial distribution across different positions and orientations helps maintain performance while keeping the device compact.
2Reliability
If the antenna size is increased to improve performance, then the antenna efficiency is improved, but the device size is increased
Solution Approach 1:
The antenna system is segmented into two separate components: the internal antenna within the electronic device and the second antenna on the assist device. This segmentation allows each antenna to be optimized for performance while the overall system remains compact, as the assist device can be attached externally when needed.
Solution Approach 2:
The assist device with the second antenna can be dynamically attached or detached based on usage conditions. When handgrip effects degrade performance, the assist device is attached to provide compensation. This dynamic approach allows the system to maintain high antenna efficiency only when needed, keeping the device compact during normal use.
3Adaptability or versatility
If the internal antenna is affected by handgrip, then the resonance frequency is shifted, but the data transmission rate is reduced
Solution Approach 1:
The system uses feedback from the second antenna to detect and compensate for handgrip effects on the internal antenna. By monitoring changes in the antenna system and adjusting accordingly through the second antenna's capacitance variation, the patent maintains stable resonance frequency and data transmission rate despite external disturbances.
Solution Approach 2:
The patent exploits parameter changes in capacitance that occur when the second antenna is attached at different positions relative to the internal antenna. By controlling the attachment position of the assist device, the system can adjust the total capacitance to compensate for handgrip-induced frequency shifts, thereby maintaining optimal data transmission performance.
