Parabolic Conductive Fingertip for Touchscreen Precision
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gloves with conductive surfaces for touchscreen operation often result in large conductive areas, making it difficult to precisely operate touchscreens, especially with smaller devices and keyboards.
Innovation Solution
A finger glove with parabolic-shaped conductive contact elements on the index finger and thumb, allowing precise surface contact at different angles and positions, featuring a first contact area on the outer surface and a second contact area on the inner surface, connected via a web, to facilitate precise touchscreen operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conductive surfaces are applied to the fingertip areas of gloves, then touchscreen operation is enabled, but the conductive surface area becomes too large for precise operation
Solution Approach 1:
The conductive surface is segmented into two separate contact areas (first contact area on outer surface, second contact area on inner surface) connected by a web. This segmentation allows the conductive material to be focused at the fingertip edge rather than covering the entire fingertip, enabling precise touchscreen operation while maintaining touchscreen capability.
Solution Approach 2:
The conductive material is concentrated at the edge area of the fingertip rather than being uniformly distributed across the entire fingertip surface. This local concentration of conductivity at the precise contact point enables accurate touchscreen selection while minimizing the overall conductive surface area.
2Manufacturing precision
If the conductive area is reduced for precise operation, then touchscreen precision improves, but contact reliability at different angles may deteriorate
Solution Approach 1:
The contact element is designed with a parabolic shape that extends in multiple directions from the fingertip edge. This three-dimensional configuration allows the contact element to maintain reliable electrical contact with the touchscreen at various finger angles and positions, compensating for the reduced surface area.
Solution Approach 2:
The contact element features a parabolic (curved) shape rather than a flat surface. This curvature allows the conductive material to conform to different contact angles and maintain reliable electrical connection regardless of the finger's orientation relative to the touchscreen surface.

AI summary
The present invention provides a glove (1) comprising at least one finger sleeve (3) with a contact element (10) made of conductive material. The contact element has a first contact area (13) and a second contact area (14), wherein the first contact area is arranged on an outer surface (17a) of the glove at a fingertip area (3a) on the palm side, and wherein the first contact area is connected to a second contact area (14), which is arranged on an inner surface of the glove, via an electrical conductor. The first contact area is limited to a fingertip-adjacent edge region of the palm fingertip area and is essentially parabolic in shape.
