Multilayer Tactile Glove Structure for Finger Motion Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tactile stimulation provision devices, such as gloves, are difficult to wear due to their thickness, which impedes finger movement and reduces the accuracy of finger motion recognition by external cameras.
Innovation Solution
A tactile stimulation provision device in the form of a glove, comprising multiple layers of fabrics and actuators, with actuators fixed between fabric patches and connected via circuit units, allowing for close contact with the user's fingers and improved finger motion recognition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the glove is filled with electronic components to provide tactile stimulation, then the tactile stimulation function is improved, but the thickness of the glove increases making finger movement difficult
Solution Approach 1:
The glove is divided into multiple fabric layers (first fabric, second fabric, third fabric) with electronic components distributed throughout. Each layer serves specific functions: the first fabric contacts the finger, the second fabric contains actuators and circuits, and the third fabric provides additional structure. This segmentation allows the electronic components to be integrated without creating a single thick block that would impede finger movement.
Solution Approach 2:
The patent uses multiple flexible fabric layers instead of rigid structures to house electronic components. The first fabric layer in direct contact with the finger is kept thin and flexible, while electronic components are embedded in subsequent layers. This approach maintains glove flexibility and comfort while integrating the required electronic functionality for tactile stimulation.
2Reliability
If the glove thickness increases to accommodate electronic components, then the tactile stimulation capability is improved, but the finger motion recognition rate by external camera decreases
Solution Approach 1:
By segmenting the glove into multiple thin layers rather than using a single thick layer, the overall structure remains more transparent to optical detection. The first fabric layer that直接接触s the finger is kept thin, allowing external cameras to better observe finger movements while subsequent layers contain the electronic components.
3Ease of operation
If the glove is made thinner to improve finger movement and recognition rate, then the ease of operation is improved, but the ability to provide tactile stimulation is reduced
Solution Approach 1:
The functional separation into multiple layers allows the first thin fabric layer to ensure ease of finger movement while the second and third layers contain the actuators and electronic components necessary for tactile stimulation. This segmentation resolves the contradiction by distributing functions across different layers.
Solution Approach 2:
The second fabric layer serves multiple functions: it provides structural support, houses the actuators for tactile stimulation, contains the circuit units for electrical connections, and maintains flexibility. This multi-functionality allows the glove to provide tactile stimulation without requiring additional thick layers.
