Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for deploying machine-readable indicia, such as QR codes, on objects are limited by the difficulty in affixing and changing them, especially on electronic display devices, which can be expensive and require permanent attachment, restricting flexibility and ease of use.
Innovation Solution
A mechanical device with integrated machine-readable indicia, such as QR codes, that can be affixed to objects using various fasteners or adhesives, allowing for flexible placement and easy removal, and can be composed of durable materials like metal or plastic, with resilient features for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If QR codes are displayed on electronic display devices, then information can be presented, but the device becomes expensive and requires permanent attachment
Solution Approach 1:
The patent uses a mechanical device with a housing that can be easily attached and removed from objects, replacing expensive electronic display devices. The housing contains the machine-readable indicia and can be deployed on various objects without requiring permanent installation or expensive electronics, thus reducing cost while maintaining reliability through secure mechanical attachment.
Solution Approach 2:
The patent creates a mechanical device that copies the function of an electronic display device without requiring the expensive electronic components. The housing with machine-readable indicia serves as a simplified copy that achieves the same information presentation function through a much cheaper mechanical structure.
2Ease of manufacture
If QR code labels are attached with adhesive, then deployment is easy, but removal and changing becomes difficult
Solution Approach 1:
The patent divides the attachment system into separate components: a housing that contains the machine-readable indicia and a mechanical attachment mechanism. This segmentation allows the housing to be easily attached to and removed from objects using mechanical fasteners, overcoming the limitation of adhesive-based systems where removal is difficult.
Solution Approach 2:
The patent employs a dynamic attachment mechanism that allows the housing to be easily attached and detached from objects. The mechanical fasteners enable the system to transition between attached and detached states, providing ease of removal and changing while maintaining secure attachment during use.
3Reliability
If QR codes are displayed on electronic display devices, then information can be presented, but flexibility and ease of use is restricted
Solution Approach 1:
The patent creates a universal mechanical device that can be attached to various different objects using mechanical fasteners. The housing with machine-readable indicia can be deployed on shopping carts, furniture, vehicles, and other objects, providing flexibility and versatility while maintaining reliable information presentation through the consistent mechanical attachment mechanism.

AI summary
Discussed herein are techniques and implementations for deployment of machine-readable indicia on objects. The deployment can be achieved with a mechanical device to affix the machine-readable indicia to an object. The machine-readable indicia can be applied to the mechanical device, which then can be affixed to the object. The mechanical device can be portable and easily affixed to the object with snap-coupling fasteners. Structures on the mechanical device can help to locate and/or maintain the device on the object.
