Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional point-of-sale systems often result in inefficient and non-fluid interactions with physical activity instruments, leading to premature insertion or cancellation of transactions due to improper readiness indication, which is not user-friendly for both users and merchants.
Innovation Solution
Incorporating magnetic components into activity computing devices and instruments that generate repulsive or attractive forces based on polarity interactions to indicate readiness for transaction, ensuring proper alignment and preventing premature insertion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If magnetic components are added to indicate readiness, then transaction fluidity is improved, but device complexity increases
Solution Approach 1:
The patent uses magnetic field polarity changes (analogous to color changes) to indicate readiness states. The magnetic component generates fields with different polarities to signal whether the activity computing device is prepared to receive the activity instrument, providing clear visual-like feedback through magnetic interaction forces.
Solution Approach 2:
The magnetic component acts as an intermediary between the activity computing device and the activity instrument. It mediates the interaction by generating magnetic fields that communicate readiness status without requiring direct physical contact or complex electronic communication protocols between the devices.
2Reliability
If magnetic field polarity is used to indicate readiness, then premature insertion is prevented, but energy consumption increases
Solution Approach 1:
The magnetic component operates periodically rather than continuously, generating magnetic fields only when needed to indicate readiness status. The system transitions between active and inactive states, consuming energy only during state transitions and status indication moments, rather than maintaining constant magnetic field generation.
Solution Approach 2:
The system changes magnetic field parameters (polarity and presence) to encode readiness information. By modulating the magnetic field characteristics rather than maintaining constant high-energy fields, the system achieves reliable communication of device state while minimizing overall energy consumption.

AI summary
A method of an activity computing device having a first magnetic component switching between a first and a second mode includes receiving a first indication of an activity, and instructing the first magnetic component to generate: when in the first mode: a first magnetic field having a first polarity that is configured to interact with a second magnetic field generated by a second magnetic component of the activity instrument, wherein the second magnetic field has a second polarity that is the same as the first polarity so that the activity computing device generates a repulsive force, and when in the second mode: a third magnetic field having a third polarity that is configured to interact with the second magnetic field generated by the second magnetic component, wherein the third polarity is opposite to the second polarity so that the activity computing device generates a pulling magnetic force.
