Electronic Card Switch Activation Validation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Involuntary activations of electronic cards due to accidental pressure during use or manufacturing lead to premature depletion of personal identification codes, causing synchronization issues and increased energy consumption, resulting in defective cards that cannot perform transactions.
Innovation Solution
The electronic card includes means to detect switch activations and validate them based on time intervals, ensuring that only intentional activations trigger the secure identification program, with a signal to the user indicating when to complete the activation, thus preventing prolonged pressure and unintentional use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the switch activation detection is immediate without time interval validation, then the card responds quickly to user input, but involuntary activations during manufacturing or accidental pressure cause premature depletion of personal identification codes
Solution Approach 1:
The patent applies dynamics by introducing a time-dependent validation mechanism for switch activation. The system dynamically evaluates whether the activation duration falls within an acceptable time interval range, allowing the same physical switch to produce different outcomes based on temporal characteristics. This resolves the contradiction by enabling quick legitimate activations while filtering out prolonged accidental presses during manufacturing or transport.
Solution Approach 2:
The patent changes the parameter of activation detection from a simple binary state (pressed/not pressed) to a temporal parameter (activation duration). By measuring and comparing the switch activation time against a predetermined interval, the system distinguishes between intentional user activation and involuntary activation during manufacturing, thereby preventing premature code depletion while maintaining responsive operation.
2Reliability
If the switch activation is validated with time interval checking, then involuntary activations are prevented, but the device complexity increases due to additional detection and timing mechanisms
Solution Approach 1:
The patent achieves multi-functionality by integrating the time interval detection capability into the existing switch activation detection circuitry. The same detection means that identifies switch activation also measures activation duration, eliminating the need for separate timing hardware. This universal approach validates activations reliably while minimizing additional device complexity.
Solution Approach 2:
The system employs self-service by utilizing the inherent temporal characteristics of the switch activation signal itself for validation purposes. The detection means analyzes the duration of the activation signal directly, without requiring external timing devices or additional sensors. This self-contained approach provides reliable activation validation while avoiding the complexity of external timing mechanisms.
3Loss of information
If multiple personal identification codes are consumed during involuntary activations, then the synchronization between card and server is maintained, but the card becomes defective more quickly with fewer usable transactions
Solution Approach 1:
The patent applies preliminary action by implementing time interval validation before personal identification codes are consumed. The system pre-establishes acceptable activation time intervals and checks incoming activations against these criteria before triggering code transmission. This preliminary filtering prevents involuntary activations during manufacturing from consuming codes, thereby extending the card's usable transaction lifespan while maintaining synchronization through legitimate activations.
4Ease of manufacture
If the switch is activated during manufacturing processes like lamination or impression, then the card production continues smoothly, but energy is wasted and codes are depleted prematurely
Solution Approach 1:
The patent applies dynamics by introducing time-dependent validation for switch activation during manufacturing processes. The system dynamically evaluates whether the activation duration falls within an acceptable time interval range, allowing the same physical switch to produce different outcomes based on temporal characteristics. This resolves the contradiction by enabling quick legitimate activations while filtering out prolonged accidental presses during manufacturing or transport.
Solution Approach 2:
The patent changes the parameter of activation detection from a simple binary state (pressed/not pressed) to a temporal parameter (activation duration). By measuring and comparing the switch activation time against a predetermined interval, the system distinguishes between intentional user activation and involuntary activation during manufacturing, thereby preventing premature code depletion while maintaining responsive operation.

AI summary
The card has a detection unit for detecting actuation of a switch. The detection unit determines whether actuation is terminated within a time interval, where the actuation is terminated after transmission of a signal perceptible to a card user. The detection unit determines whether the switch actuation is terminated within another time interval (T2max) during transmission of the signal, where the actuation is validated when the detection unit detects termination of the switch actuation within the intervals.
