Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In densely populated areas, users face difficulty in finding the specific device they need to establish a connection due to the large number of available devices within the wireless connection range, making it hard to identify the target device among many.
Innovation Solution
A method where a terminal device transmits a ranging signal, receives feedback information from nearby devices, calculates and arranges the devices in ascending order of distance, and displays the list to the user, allowing quick identification of the target device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If wireless connection search displays all available devices within transmission range, then the searching radius is maximized, but the user cannot quickly identify the target device among numerous devices
Solution Approach 1:
The patent applies local quality by differentiating devices in the search results based on their distance from the terminal device. Nearby devices are highlighted or prioritized in the display, while distant devices are de-emphasized. This creates a quality gradient in the information presentation, allowing users to quickly identify nearby target devices without reducing the overall searching radius.
2Quantity of substance
If the transmission distance is increased to cover more devices, then more devices are available for connection, but the complexity of selecting the target device increases
Solution Approach 1:
The patent extracts the distance information as a key distinguishing feature from the search results. By calculating and utilizing the distance between the terminal device and each discovered device, the system separates nearby devices from distant ones in the presentation layer. This extraction of distance as a sorting criterion simplifies the selection process while maintaining access to all available devices within transmission range.
3Adaptability or versatility
If all devices within searching radius are displayed, then connection options are maximized, but the time to find the target device increases
Solution Approach 1:
The patent performs preliminary sorting of devices based on distance information before presenting the search results to the user. By pre-calculating distances and organizing devices in order of proximity, the system prepares the information in an optimized format that enables faster target device identification. This preliminary arrangement maintains all connection options while reducing the time users need to spend searching.
