Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face challenges in accurately entering account data on small keyboards due to fat or swift fingers, leading to inaccurate data entry and potential fraudulent transactions.
Innovation Solution
The system uses symbols to represent payment accounts, allowing selection through voice commands, touch screens, or pointers, eliminating the need for manual typing and improving data entry accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual typing is used to enter account data, then data entry can be completed, but input accuracy deteriorates due to fat or swift fingers on small keyboards
Solution Approach 1:
The patent uses visual symbols (icons, emojis, graphics) to represent payment accounts instead of requiring manual typing of account numbers. Users select accounts by tapping on their corresponding symbols, which are visual copies or representations of the account identity. This eliminates typing errors while maintaining ease of operation.
Solution Approach 2:
The patent replaces the mechanical typing process with a visual selection process. Instead of physically typing account numbers on a keyboard, users interact with visual symbols on a touchscreen interface. The system automatically retrieves and populates account data when a symbol is selected, substituting manual mechanical input with automated digital retrieval.
2Productivity
If manual typing is required for payments, then transaction execution is possible, but user convenience deteriorates due to increased typing effort
Solution Approach 1:
The system performs preliminary actions by pre-associating visual symbols with account data and pre-configuring the payment interface with selectable symbols. When a user initiates a payment, the relevant account symbols are already prepared and displayed, eliminating the need for users to manually type or search for account information during the transaction.
Solution Approach 2:
Visual symbols serve as copies or representations of payment accounts, allowing users to select accounts through intuitive graphical interfaces rather than typing. This copying approach maintains rapid transaction execution while significantly improving user convenience through familiar visual interaction patterns.
3Reliability
If account data is manually entered, then transactions can be processed, but security deteriorates due to potential fraudulent entries
Solution Approach 1:
The system incorporates feedback mechanisms where visual symbols provide immediate confirmation of account selection. When a user taps a symbol, the system provides feedback by displaying the selected account information and proceeding with the transaction using that specific account. This feedback loop prevents fraudulent entries by ensuring the user intends to use the displayed account.
Solution Approach 2:
The patent replaces manual data entry with automated account retrieval triggered by symbol selection. When a user selects a visual symbol, the system automatically retrieves the associated account data from secure storage and populates the payment fields. This substitution eliminates the security vulnerability of manual entry while adding minimal complexity through automated data retrieval and validation.
Data Source
AI summary
Symbols are used to represent payment accounts. The symbols may be programmed to represent accounts and the data for the accounts may be entered into appropriate fields when the symbol is selected. Once selected, account data is retrieved and is communicated to the proper field in the data entry screen. The account data is then used to complete the transaction.
