Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If pressure-sensitive touch screens are incorporated, then user input precision and automation capability are improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent combines pressure sensitivity detection with the existing touch screen structure by integrating pressure-sensitive materials or sensors into the touch screen layers. This merging approach allows the touch screen to simultaneously detect both touch location and pressure magnitude without adding separate independent systems, thereby improving measurement precision while limiting the increase in device complexity.
Solution Approach 2:
The touch screen is designed to serve multiple functions: basic touch detection, pressure magnitude detection, and automated action triggering. By making the touch screen multi-functional, the patent extracts maximum utility from a single component, improving measurement precision for pressure while avoiding the need for additional dedicated pressure sensing devices that would increase complexity.
2Reliability
If multiple input options are required for payment applications, then payment security and control are improved, but user operation time and efficiency deteriorate
Solution Approach 1:
The patent utilizes pressure magnitude as an additional parameter to differentiate between various payment actions. By mapping different pressure ranges to specific functions (e.g., light pressure for review, heavy pressure for confirm), the system maintains high reliability through multiple verification parameters while reducing the number of discrete input steps required, thereby decreasing the time to complete payment transactions.
Solution Approach 2:
The system pre-configures automated actions associated with specific pressure thresholds. When a user applies the predetermined pressure, the corresponding action is automatically executed without requiring additional confirmation steps or menu navigation. This preliminary configuration of pressure-action mappings maintains transaction reliability while significantly reducing the time required to complete payment inputs.
3Adaptability or versatility
If pressure sensitivity is added to touch screens, then input versatility and automation capability are improved, but manufacturing cost and complexity increase
Solution Approach 1:
The patent employs thin-film pressure-sensitive materials or flexible sensor layers that can be deposited or laminated onto the existing touch screen structure. These thin-film solutions enable pressure sensitivity to be added through relatively simple manufacturing processes such as sputtering, evaporation, or lamination, rather than requiring complex rigid sensor assemblies, thereby improving input versatility while maintaining ease of manufacture.

AI summary
There are provided systems and methods for measuring tap pressure on mobile devices to automate actions. A computing device, such as a mobile smart phone, may include a touch screen interface that may accept touch inputs. A touch input may include a presence and location of the touch input on the touch screen interface. Additionally, the computing device may detect a pressure or force applied to the touch screen interface with the touch input. The computing device may include a payment application, where the touch input may be received during use of the payment application. The pressure of the touch input may further define the input for the payment application. For example, a touch input with a first pressure may cause a first process to be initiated, while a second pressure may cause a second process to be initiated.
