Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If touch devices are used to replace physical input devices, then the elevator system achieves a more modern interface, but the user experience becomes inconsistent and unresponsive due to lack of haptic feedback
Solution Approach 1:
The patent implements haptic feedback mechanisms in touch devices that provide tactile responses to user interactions. The control unit generates haptic output signals based on detected user indications and status information, creating a feedback loop that makes the touch interface feel responsive and adaptive, resolving the contradiction between modern touch interfaces and responsive user experience.
Solution Approach 2:
The system dynamically adjusts haptic feedback characteristics (amplitude, duration, pattern) based on real-time status information including building status, user status, device status, and theme-based status. This dynamic adaptation allows the same touch interface to provide different haptic responses depending on context, achieving both versatility and responsiveness.
2Adaptability or versatility
If static haptic feedback is implemented, then the system structure remains simple, but the user experience lacks customization and adaptability to different situations
Solution Approach 1:
The patent changes the parameters of haptic feedback (amplitude, duration, pattern) based on multiple status inputs. The control unit receives status information about the building, user, device, and theme, then dynamically adjusts haptic parameters to provide customized feedback for different situations, achieving adaptability without requiring fundamentally different hardware for each scenario.
Solution Approach 2:
The control unit serves multiple functions: detecting user indications, receiving various status information inputs, processing this data, and generating appropriate haptic output signals. This multi-functional approach allows a single control system to handle diverse feedback requirements without needing separate specialized systems for each function.
3Ease of operation
If haptic feedback is added to touch devices, then user experience is enhanced, but the device complexity and control requirements increase
Solution Approach 1:
The patent merges the haptic feedback functionality with the existing touch device and control unit. The haptic output generator is integrated into the user interface device, and the control unit that already processes user inputs now also controls haptic feedback. This combining approach enhances user experience while minimizing the increase in overall system complexity by reusing existing components.
Data Source
AI summary
A method for a haptic feedback system for one or more elevator systems includes detecting a user indication provided via a user interface device of one of the one or more elevator systems, receiving at least one status information, and generating a haptic output signal via the user interface device in accordance with the at least one status information. A control unit, a haptic feedback system and a computer program performing at least part of the method is disclosed.
