Function Execution Apparatus Wireless Connection Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing function execution apparatuses face challenges in establishing wireless connections with new devices when the upper limit number of connections is reached, as they lack an efficient method to manage and disconnect existing connections to accommodate new requests.
Innovation Solution
A function execution apparatus that includes a controller, capable of receiving a wireless connection request, transmitting an inquiry signal to existing devices to determine if they activate a specific application program, selecting a target device to disconnect based on the inquiry results, and establishing a connection with the new device after disconnection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the function execution apparatus maintains wireless connections with N devices (upper limit), then connection stability is ensured, but the ability to accept new connection requests is lost
Solution Approach 1:
The system performs preliminary actions by sending inquiry signals to existing connected devices before finalizing a new connection. This allows the system to proactively identify and prepare for connection transitions by checking application activation states in advance, ensuring smooth handover while maintaining connection stability
Solution Approach 2:
The connection management system dynamically adjusts connections based on real-time application activation states. When a new connection request arrives, the system dynamically evaluates the status of existing connections and transitions connections adaptively, allowing the system to maintain stability while accommodating new connections
2Adaptability or versatility
If the apparatus disconnects existing connections to accommodate new requests, then adaptability is improved, but connection management complexity increases
Solution Approach 1:
The system uses feedback mechanisms by sending inquiry signals to existing devices and receiving responses about their application activation states. This feedback loop enables intelligent decision-making for connection management, allowing the system to determine which connections to maintain or disconnect based on actual usage states, reducing unnecessary complexity
Solution Approach 2:
The system performs self-service by automatically evaluating connection states and making disconnection decisions without external intervention. The controller autonomously sends inquiry signals, processes responses, and determines which connections to terminate, simplifying the overall management process while maintaining adaptability
3Measurement precision
If the apparatus sends inquiry signals to all N connected devices, then connection selection accuracy is improved, but communication overhead increases
Solution Approach 1:
The system applies partial action by sending inquiry signals to only the necessary subset of connected devices (K devices) rather than all N devices. This selective approach maintains sufficient accuracy in connection selection by targeting devices that are relevant to the new connection request, while reducing overall communication overhead

AI summary
There is provided a function execution apparatus which, when a wireless connection request is received from a specific device in a specific state where wireless connections are established between the function execution apparatus and N devices which are an upper limit number of devices, transmits an inquiry signal to each of K devices among the N devices to inquire whether each device which is a final transmission destination of the inquiry signal activates a specific application program for causing the function execution apparatus to execute a specific function; select a target device, for which the wireless connection is to be disconnected, among the K devices based on a result of the inquiry; disconnect a wireless connection with the target device; and establish a wireless connection with the specific device after the wireless connection with the target device is disconnected.
