Haptic Pen Vibration Transfer to the Finger Contact Point
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pens that generate tactile feedback through external or end-mounted vibrating units face issues with ungainly design, power consumption, and ineffective vibration distribution, as they often vibrate areas other than the intended finger position.
Innovation Solution
A pen with a built-in haptic element and an offset transmitting section inside the housing, which transmits vibrations to the finger position without shaking the entire pen, using a structure that includes a processing circuit, signal transmitting section, and haptic elements fixed to the housing with an offset transmitting mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an external vibrating unit is attached to the pen, then tactile feedback can be provided to the finger position, but the design becomes ungainly and prone to failure
Solution Approach 1:
The patent extracts the vibrating unit from the external attachment and integrates it internally into the pen structure. Specifically, a vibrating unit is provided inside the housing at a position apart from the finger position, eliminating the need for external attachments while maintaining the tactile feedback function.
Solution Approach 2:
The patent introduces an offset transmitting section as an intermediary mechanism between the internally positioned vibrating unit and the finger position. This offset transmitting section transmits the vibration from the vibrating unit to the finger position, enabling tactile feedback without requiring the vibrating unit to be located directly at the finger position.
2Ease of operation
If a vibrating unit is installed at the end of the pen, then tactile feedback can be provided, but the entire pen shakes and power consumption increases
Solution Approach 1:
The patent applies local quality by positioning the vibrating unit at a specific location inside the housing (apart from the finger position) and using the offset transmitting section to direct the vibration specifically to the finger position. This localized approach ensures that only the necessary area vibrates, reducing overall power consumption compared to shaking the entire pen.
Solution Approach 2:
The offset transmitting section serves as a mediator that efficiently transmits vibration from the vibrating unit to the finger position with minimal energy loss, preventing unnecessary vibration of the entire pen structure and reducing power consumption.
3Ease of operation
If a vibrating unit is installed at the end of the pen, then tactile feedback can be provided, but areas other than the finger position are also vibrated reducing effectiveness
Solution Approach 1:
The patent implements local quality by strategically positioning the vibrating unit inside the housing at a location apart from the finger position, and using the offset transmitting section to direct vibration precisely to the finger position. This ensures that only the intended area receives vibration, improving targeting precision.
Solution Approach 2:
The offset transmitting section acts as a precision intermediary that channels the vibration energy specifically to the finger position, preventing dispersion of vibration to unrelated areas and ensuring accurate tactile feedback delivery.
