Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing techniques are used for providing feedback about contactless account information transfers, then user feedback is provided, but the process is cumbersome and time-consuming requiring multiple key presses or keystrokes
Solution Approach 1:
The patent extracts and eliminates unnecessary intermediate steps (multiple key presses) from the account information transfer process. By detecting proximity-based error conditions and providing targeted feedback, the system removes redundant user actions while maintaining transfer completion capability.
Solution Approach 2:
The system implements proactive feedback by detecting when error conditions occur during contactless transfer and immediately providing guidance on how to complete the request. This feedback loop prevents users from needing to understand complex error states, simplifying the interaction.
2Reliability
If existing techniques are used for providing feedback about contactless account information transfers, then user feedback is provided, but device energy is wasted particularly in battery-operated devices
Solution Approach 1:
The system performs preliminary detection of error conditions during the transfer process and provides guidance before the transfer fails. This preliminary action prevents wasted energy on attempting to complete transfers that would inevitably fail, while ensuring reliable completion when conditions are favorable.
Solution Approach 2:
The system monitors its own transfer process and automatically detects error conditions, then provides self-correcting guidance to the user. This self-service approach eliminates the need for complex external error handling mechanisms, reducing energy consumption while maintaining reliability.
3Productivity
If existing techniques are used for account information transfer, then transfers can be completed, but cognitive burden on user is increased
Solution Approach 1:
The system provides simplified feedback that directly addresses the user's immediate need: how to complete the transfer request. By detecting error conditions and providing targeted guidance rather than complex error codes or multiple menu options, the system reduces cognitive burden while maintaining transfer speed.
Solution Approach 2:
The patent segments the transfer process into distinct phases, monitoring for specific error conditions at each phase. This segmentation allows the system to provide targeted, simple feedback for each specific error type rather than presenting a single complex interface for all possible errors, reducing cognitive load.
