Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If visual interfaces are used to distinguish applications, then application differentiation is achieved, but user engagement and tactile experience remain limited
Solution Approach 1:
The patent introduces a new dimension of interaction by adding tactile feedback capabilities to the traditional visual interface. E-tattoo structures are integrated into the display screen to provide localized haptic feedback, transforming a two-dimensional visual experience into a multi-sensory interaction that includes touch sensation. This allows applications to differentiate themselves through tactile cues without complicating the visual interface design.
Solution Approach 2:
The e-tattoo structures are positioned at specific locations on the display screen corresponding to different applications or interface elements. Each e-tattoo can be independently controlled to provide customized tactile feedback patterns, allowing localized differentiation of applications without affecting the entire interface. This enables precise tactile communication tailored to specific user needs and application contexts.
2Ease of operation
If tactile feedback is added to the display screen, then user interaction is enhanced, but device complexity increases
Solution Approach 1:
The patent combines the e-tattoo haptic feedback structures with the existing display screen structure, integrating multiple functions into a unified component. The e-tattoos are embedded within the display layers, sharing the same physical space and structural support as the visual display elements. This merging approach enables tactile feedback functionality without requiring separate dedicated components or significantly increasing overall device complexity.
Solution Approach 2:
The e-tattoo structures serve multiple functions simultaneously: they provide tactile feedback for user interaction, maintain the display screen's visual output capability, and can be controlled independently for different applications. This multi-functionality allows a single integrated structure to fulfill both visual and tactile interaction requirements, reducing the need for additional separate components.
3Ease of operation
If e-tattoo structures are integrated into the display, then tactile feedback is provided, but manufacturing complexity increases
Solution Approach 1:
The e-tattoo structures are pre-formed as separate components before being integrated into the display assembly. This preliminary preparation allows for standardized manufacturing of the haptic elements using established techniques, and enables quality control to be performed on the e-tattoos independently before final assembly. The pre-formed structures can be precisely positioned and connected to control circuits during the display manufacturing process, simplifying the overall integration step.

AI summary
A computer system associates one or more haptic feedbacks with one or more user activities. The computer system monitors current user activity on a computing device to determine whether the current user activity corresponds to at least one of the one or more user activities. In response to determining that the current user activity corresponds to a first user activity of the one or more user activities, the computer system causes a first haptic feedback of the one or more haptic feedbacks to be provided on the computing device, wherein the first haptic feedback is associated with the first user activity.
