Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If automatic connection is implemented without direction information, then connection speed is improved, but connection accuracy deteriorates causing unintended connections
Solution Approach 1:
The patent introduces direction information as an intermediary parameter to mediate between automatic connection speed and connection accuracy. The direction information (obtained via sensors or user input) serves as a mediator that guides the automatic connection process, ensuring that the information processing device connects to the intended electronic device rather than any device in range. This resolves the contradiction by adding a guiding layer that maintains both speed and accuracy.
2Measurement precision
If manual device selection is required, then connection accuracy is improved, but ease of operation deteriorates due to user burden
Solution Approach 1:
The patent enables the system to perform self-service by automatically selecting the connection target based on direction information. Instead of requiring manual user selection, the information processing device uses its sensors or obtained direction data to autonomously identify and connect to the intended electronic device. This maintains high connection accuracy while eliminating the user burden of manual selection.
3Measurement precision
If direction information acquisition is added, then connection accuracy is improved, but device complexity increases
Solution Approach 1:
The patent leverages multi-functionality by utilizing existing sensors or communication capabilities already present in the information processing device for direction information acquisition. Rather than adding dedicated new hardware, the system repurposes existing components (such as camera, sensors, or wireless communication units) to obtain direction data, thereby improving connection accuracy while minimizing the increase in device complexity.

AI summary
An information processing device wirelessly communicates with an electronic device via a wireless communication unit and includes a search result acquisition unit, an input information acquisition unit, a direction information acquisition unit, and a controller. The search result acquisition unit acquires information of a search result about the electronic device. The input information acquisition unit acquires input information inputted as a direction of the electronic device that is a connection target, in relation to the information processing device. The direction information acquisition unit acquires direction information representing a direction in which the electronic device exists, by short-range wireless communication with the electronic device. The controller executes processing of specifying the electronic device corresponding to the input information from among the electronic devices found by the search, based on the direction of the direction information and the direction of the input information, and connecting to the specified electronic device.
