Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing electronic signature systems on mobile devices with small screens are difficult to use, leading to time-consuming signature drawing and often result in illegible signatures, which can cause administrative burdens and missed deadlines due to denial by authorities.

Innovation Solution

A computer-implemented method and system that calculates an appropriate font size for an electronic signature based on the user's name length, allowing for automatic drawing and fitting within a specified field, with the option to manually draw if necessary, and enabling single-click submission.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If users manually draw signatures on small mobile screens, then the system supports electronic signature functionality, but the process becomes time-consuming and signatures become illegible

Engineering Contradiction:

Improveease of signature creationVSAvoidtime consumption for signature drawing

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The system automatically generates the electronic signature by rendering the user's name in a stylized font, eliminating the need for manual drawing. The computer executes code that transforms the typed name into a signature-like representation, making the system serve itself rather than requiring user effort for the actual signature creation.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces the mechanical action of manually drawing with a mouse or stylus with an automated computational process. The system uses font rendering technology to generate the signature visually, substituting physical drawing mechanics with digital text transformation.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If users manually draw signatures on small mobile screens, then the system supports electronic signature functionality, but signature legibility deteriorates

Engineering Contradiction:

Improveease of signature creationVSAvoidsignature legibility

Core Design Contradiction:

Ease of operationVSManufacturing precision

Solution Approach 1:

Inventive Principle:

Principle #25Self-service

3Productivity

If automatic font size calculation is implemented, then signature generation becomes faster, but adaptability to different name lengths must be maintained

Engineering Contradiction:

Improvesignature generation speedVSAvoidadaptability to different name lengths

Core Design Contradiction:

ProductivityVSAdaptability or versatility

Solution Approach 1:

The system dynamically adjusts the font size based on the length of the user's name. The code calculates an appropriate font size that ensures the signature fits within the designated space while maintaining legibility, allowing the signature generation process to adapt to varying input conditions automatically.

Inventive Principle:

Principle #15Dynamics

AI summary

A method for electronic signature is provided. The method comprises capturing a user name through an interface and calculating a font size for an electronic signature of the user name based on the number of characters in the user name. The electronic signature of the user name is drawn using the font and calculated font size, and a determination is made if the electronic signature fits within a specified field of an electronic form. If the electronic signature fits within the specified field the electronic signature is submitted in the electronic form.
