Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The distribution of biometrically enabled smartcards with plastic enrollment sleeves for one-time use is costly and environmentally problematic.
Innovation Solution
An enrollment assistance device comprising a carrier and an electronic label with a card interface and power supply portion, allowing biometric enrollment by folding the label over the carrier edge to attach to the smartcard, utilizing cost-effective and recyclable materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If plastic enrollment sleeves with battery or USB-connection are distributed for biometric enrollment, then the enrollment function is provided, but the distribution cost increases and environmental impact worsens
Solution Approach 1:
The patent replaces the traditional plastic enrollment sleeve with a reusable enrollment assistance device that has a carrier and electronic label. The electronic label can be reused multiple times for enrollment purposes, eliminating the need for single-use plastic sleeves and reducing material waste while maintaining the enrollment function.
Solution Approach 2:
The patent enables recovery and reuse of the enrollment assistance device. The electronic label with card interface portion and power supply portion can be attached to and detached from the carrier, allowing the device to be reused across multiple enrollment sessions rather than being discarded after single use.
2Ease of operation
If plastic enrollment sleeves are distributed for biometric enrollment, then the enrollment function is provided, but the distribution cost increases
Solution Approach 1:
The enrollment assistance device serves multiple functions: the carrier provides structural support and protection, the electronic label provides power supply and communication interfaces, and the combination enables reusable enrollment assistance. This multi-functionality reduces the need for separate components and lowers distribution costs compared to single-use plastic sleeves.
Solution Approach 2:
The reusable nature of the enrollment assistance device allows it to be recovered and reused across multiple enrollment sessions, significantly reducing the cumulative distribution cost compared to continuously producing and distributing single-use plastic sleeves.
3Loss of substance
If electronic label is folded over carrier edge to attach to smartcard, then material waste is reduced, but device complexity increases
Solution Approach 1:
The electronic label is divided into distinct functional portions: a card interface portion for interacting with the smartcard and a power supply portion for receiving power. This segmentation allows each portion to be optimized independently and simplifies the overall assembly process despite the folded configuration.
Solution Approach 2:
The electronic label is folded over the carrier edge, nesting the card interface portion and power supply portion in a compact arrangement. This nesting approach reduces the overall material footprint and simplifies the structure while maintaining all necessary functional elements.
