Smart Conversion Button for Keypad Command Execution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable terminals require complex user operations to access various information services, such as weather or translation, and lack an efficient method for inputting commands beyond the languages supported by the keypad, limiting user convenience.
Innovation Solution
A user device with a smart conversion button that allows users to input commands through a keypad, recognizing specific characters or strings to execute intelligent services like translation or information retrieval, and providing results without leaving the current execution screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a simple designated character input function is used in the portable terminal, then the device complexity is reduced, but the adaptability for supporting multiple languages and command execution is limited
Solution Approach 1:
The keypad is designed to serve multiple functions: it can input both traditional characters and command strings for executing intelligent services. The same physical keys are used for both character input and command execution, eliminating the need for separate language-specific keypads and enhancing versatility without increasing device complexity
Solution Approach 2:
The keypad's functionality is made dynamic by allowing it to switch between character input mode and command execution mode based on the input content. The system dynamically interprets whether the input is a regular character or a command string, enabling the keypad to adapt to different input purposes without physical reconfiguration
2Reliability
If the user switches to a different function to access information services, then the information service functionality is improved, but the ease of operation is reduced due to requiring function switching and complex procedures
Solution Approach 1:
The command execution function for intelligent services is merged into the current application's execution screen. Users can input commands directly in the message or chat interface without switching to a separate information service application, combining multiple functions into a unified workflow that simplifies operation
Solution Approach 2:
The system prepares command execution by pre-defining command strings and their corresponding actions. When a user inputs a recognized command string, the system immediately executes the associated intelligent service without requiring the user to manually navigate through multiple steps or switch applications, performing the service activation in advance based on command recognition
3Adaptability or versatility
If multiple languages are supported through separate keypads, then the adaptability is improved, but the device complexity and installation requirements increase
Solution Approach 1:
A single universal keypad supports multiple languages and command inputs without requiring separate language-specific keypads. The same physical keyboard is used to input both characters and command strings for various languages, eliminating the need to search for, install, and manage multiple language keypads
Solution Approach 2:
The language-specific keypad functionality is extracted and replaced by a command string interpretation mechanism. Instead of relying on physical keypad configurations for different languages, the system extracts the essential function of language support by recognizing command strings and executing corresponding intelligent services, simplifying the keypad's role

AI summary
A method of providing a service using a keypad is provided. The method includes displaying a text box and a keypad on an executed screen, inputting a start identifier according to a selection of a smart conversion button of the keypad, inputting a command after the identifier, inputting a termination identifier after the command, performing an intelligent service according to the command when the termination identifier is inputted, and outputting a result according to the intelligent service in the text box.
