Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optically scannable codes, such as QR codes, are not capable of receiving and transmitting radio waves, limiting their functionality beyond data encoding in geometric representations.
Innovation Solution
A QR code antenna is developed by configuring a substrate with a bounded arrangement of electrically conductive modules, forming conducting pathways to create an antenna pattern that integrates data encoding and radio wave transmission, allowing the code to function as both a data carrier and a radio frequency antenna.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If geometric representations are used to encode data in a scannable code, then data encoding capability is improved, but radio wave transmission capability deteriorates (the code cannot receive or transmit radio waves)
Solution Approach 1:
The patent merges the geometric representation structure with antenna functionality by configuring specific modules as conductive elements. The boundaried arrangement of modules forms both the scannable code pattern and a functional antenna structure that can receive and transmit radio waves, enabling dual functionality in a single integrated design.
Solution Approach 2:
The patent creates a multi-functional structure where the same geometric modules serve dual purposes: encoding data for optical scanning and functioning as antenna elements for radio frequency communication. This universal design allows the scannable code to perform both data storage and wireless communication functions.
2Adaptability or versatility
If conducting pathways are added to enable radio wave transmission, then radio wave transmission capability is improved, but device complexity deteriorates
Solution Approach 1:
The conducting pathways are integrated directly into the existing module structure of the scannable code. Rather than adding separate antenna components, the patent configures the module boundaries and connections to form continuous conductive pathways that serve as antenna elements, thereby avoiding additional structural complexity.
Solution Approach 2:
The same module structure that defines the geometric pattern for optical scanning also serves as the antenna structure for radio wave transmission. The modules and their interconnections perform dual functions, eliminating the need for separate antenna components and reducing overall device complexity.
3Adaptability or versatility
If modules are configured as antenna elements with conducting pathways, then radio wave transmission is improved, but manufacturing precision requirements deteriorate
Solution Approach 1:
The antenna structure is segmented into discrete modules that correspond to the scannable code's geometric units. Each module can be independently defined and manufactured, with standardised connection points that simplify assembly and reduce precision requirements compared to continuous antenna structures.
Solution Approach 2:
The modules serve dual functions as both code elements and antenna segments, allowing the same manufacturing process to produce both the optical pattern and the RF structure. This eliminates the need for separate high-precision antenna fabrication and alignment processes.
