Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing haptic feedback systems fail to dynamically adjust to changes in the size or shape of a medium, leading to altered standing waves, lack of awareness of medium alterations, and human error in data entry, which degrade user experience and haptic performance.
Innovation Solution
A system integrating sensors and adaptive circuitry with AI algorithms to detect real-time changes in medium size or shape, optimizing haptic feedback parameters such as amplitude and wavelength to maintain effective tactile experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the size or shape of the medium changes, then the standing wave pattern is altered, but the haptic feedback system cannot compensate for this change
Solution Approach 1:
The system uses traces with altering properties to detect medium size/shape changes and feeds this information back to the processor, which then adjusts the haptic feedback frequency to maintain consistent standing wave patterns despite medium alterations
Solution Approach 2:
The haptic feedback frequency is dynamically adjusted in real-time based on detected medium changes, allowing the system to adapt its operating parameters to maintain reliable standing wave patterns across varying medium conditions
2Device complexity
If manual data entry is used for medium size, then the system can be simple, but human error occurs
Solution Approach 1:
The system automatically detects medium size and shape changes through the trace properties without requiring manual user input, eliminating human error while maintaining relatively simple system architecture through self-measurement capabilities
3Ease of operation
If the haptic feedback frequency is fixed, then the system is simple to operate, but it cannot adapt to medium changes
Solution Approach 1:
The system automatically detects medium changes through trace properties and adjusts the haptic feedback frequency without requiring user intervention, maintaining ease of operation while enabling dynamic adaptation to medium variations

AI summary
A haptic feedback mechanism for a medium includes: a sensor disposed within the medium having a size; circuitry in communication with the sensor; conductive traces in communication with the circuitry, the traces having properties that alter when the size of the medium changes; and a processor configured to: determine changes in the size of the medium based on a unique pattern of the traces generated by the changes in the size of the medium, and optimize a frequency of a haptic harmonic that generates a standing wave on a haptic actuator proximate to the medium. A method for providing dynamic adjustment of haptic feedback for a medium includes: determining that a size of the medium has changed, thereby generating detected changes; and based on the detected changes, optimizing a frequency of a haptic actuator to produce a standing wave within at least a portion of the medium.
