Hand Stamp With Static QR Code And Adjustable Type Bridge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hand stamps lack a simple and cost-effective method for reliable authentication of objects, often having complex structures and insufficient authentication features, making them cumbersome to use and difficult to distinguish between similar products.
Innovation Solution
A hand stamp with a static cliché and an adjustable type unit featuring a two-dimensional stamp code, where the static cliché contains encoded information and the adjustable type unit allows for different printing types, enabling secure and unique authentication of objects by encoding user IDs and supporting surface adjustments for precise positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a programmable stamp with movable image elements is used, then authentication capability is improved, but device complexity increases and ease of operation deteriorates
Solution Approach 1:
The patent extracts the authentication function from a complex programmable stamp system and implements it through a simple two-dimensional stamp code integrated into the static cliché. This separates the authentication mechanism (static code) from the variable information (adjustable type unit), eliminating the need for complex actuators and holding devices while maintaining reliable authentication capability.
2Reliability
If a programmable stamp with movable image elements is used, then authentication capability is improved, but ease of operation deteriorates
Solution Approach 1:
The patent removes the complex operation requirements of programmable stamps by extracting the authentication function into a static two-dimensional code that requires no actuation. The adjustable type unit simply overlays variable information on top of this static code, allowing users to operate the stamp intuitively without understanding complex programming or actuation mechanisms.
3Ease of manufacture
If hand stamps without unique identification are used, then manufacturing simplicity is maintained, but reliability of authentication deteriorates
Solution Approach 1:
The patent merges the authentication identification function directly into the static cliché by integrating a two-dimensional stamp code. This code is manufactured as an integral part of the stamp plate alongside the static text, eliminating the need for separate identification mechanisms while ensuring that each stamp has unique, reliable authentication capability.
4Device complexity
If adjustable type units without precise positioning are used, then device simplicity is maintained, but measurement precision of position deteriorates
Solution Approach 1:
The patent creates an equipotential positioning system where the bridge with support surface provides a standardized reference plane for all adjustable type units. This ensures that each type carrier aligns precisely with the static cliché and two-dimensional code, maintaining consistent positioning accuracy across different settings without requiring complex individual positioning mechanisms for each type.
