Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face challenges in accurately entering account data on small device screens, leading to inaccuracies and potential fraudulent transactions due to the laborious entry of numbers and letters for electronic payments.
Innovation Solution
The use of symbols to represent payment accounts, selectable via touch, voice, or joystick, which are recognized by the system to automatically populate data fields, reducing the need for manual typing and enhancing accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users manually type account data on small device screens, then payment transactions can be executed, but input errors increase and data entry becomes laborious
Solution Approach 1:
The system pre-stores account data (account numbers, routing numbers, bank names) in a database before the transaction occurs. When a user initiates a payment, the system automatically retrieves and populates the relevant fields with the pre-stored data, eliminating the need for manual typing and ensuring accuracy.
Solution Approach 2:
The system automatically retrieves account information from its own database and populates the payment form fields without requiring user intervention for data entry. The system serves itself by providing the necessary account data, reducing both manual effort and potential for errors.
2Productivity
If users manually enter account information, then transactions can be processed, but the process becomes time-consuming and inefficient
Solution Approach 1:
Account data is pre-stored in the system database during account setup or previous transactions. When a payment is initiated, the system quickly retrieves this pre-stored data and auto-populates the form, dramatically reducing the time required for data entry compared to manual typing.
Solution Approach 2:
The system replaces the mechanical action of manual typing with an automated electronic retrieval and population process. The computer system automatically fetches account information from the database and fills in the payment fields, eliminating the time-consuming manual input process.
3Reliability
If traditional manual entry methods are used, then payments can be made, but security risks increase due to potential fraudulent entries
Solution Approach 1:
The system provides feedback to the user by displaying the auto-populated account information (account number, bank name, routing number) for verification before submission. This allows users to confirm that the correct account data is being used, preventing fraudulent transactions caused by manual entry errors or malicious input.
Solution Approach 2:
The system automatically retrieves and populates account data from its own secure database, eliminating the need for users to manually enter sensitive financial information. This self-service approach reduces security risks by preventing users from accidentally or intentionally entering incorrect or fraudulent account details.
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.
