Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Transaction cards often require specific orientations for chip and magnetic stripe readers, leading to inefficient resource utilization and prolonged transaction times due to improper orientations.
Innovation Solution
Transaction cards are designed with electrical contact sets and magnetic stripe areas on both surfaces, allowing for readability in any orientation, ensuring efficient resource use and faster transaction processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a transaction card has electrical contact sets and magnetic stripe areas on only one surface, then the card structure is simple, but the card requires specific orientation for reading, leading to prolonged transaction times and inefficient resource utilization
Solution Approach 1:
The card is segmented into two surfaces, with each surface containing electrical contact sets and magnetic stripe areas. This segmentation allows the card to function in multiple orientations, as either surface can be positioned to interface with the reader, thereby resolving the contradiction between operational ease and structural simplicity.
Solution Approach 2:
Both surfaces of the card are equipped with identical functional elements (electrical contact sets and magnetic stripe areas), making the card universal in its orientation requirements. The card can be inserted or swiped in any orientation without requiring repositioning, thus improving ease of operation while maintaining a relatively simple structure.
2Loss of energy
If a transaction card requires specific orientation for reading, then the card structure is simple, but computing, power, and network resources are wasted due to failed read attempts
Solution Approach 1:
By dividing the card into two functional surfaces with identical elements, the system eliminates failed read attempts caused by orientation issues. The reader can successfully read the card regardless of which surface is presented, thereby reducing energy waste from retry attempts while keeping the card structure relatively simple.
Solution Approach 2:
The card is pre-configured with functional elements on both surfaces, ensuring that regardless of how the card is inserted or swiped, the reader will immediately encounter valid data. This preliminary preparation prevents wasted resource expenditure on failed read attempts.
3Productivity
If a transaction card has functional elements on both surfaces, then transaction processing is faster and resources are used efficiently, but the card structure becomes more complex
Solution Approach 1:
The card structure is segmented into two surfaces, each independently capable of interfacing with the reader. This segmentation enables faster transaction processing by eliminating the need for repositioning or retry attempts, while the modular nature of the segmentation keeps the manufacturing process manageable.
Solution Approach 2:
Both surfaces of the card perform the same function, making the card universally compatible with readers regardless of orientation. This multi-functionality accelerates transaction processing by ensuring successful reads on the first attempt, while the uniform design simplifies rather than complicates the overall structure.
