Solution Overview

Problem

The high profit margins on consumables make them vulnerable to counterfeiting, as counterfeiters can sell low-cost, low-quality alternatives, damaging legitimate suppliers' profits and reputations, and existing methods to combat counterfeiting are costly and ineffective.

Innovation Solution

Implementing a pay-for-use pricing plan where consumers are charged for the actual use of consumables, such as a flat fee or per-use basis, reducing the incentive for counterfeit production by aligning the price of legitimate and counterfeit consumables and allowing legitimate suppliers to collect charges even if counterfeit products are used.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If legitimate suppliers charge high prices for consumables, then they can maintain high profit margins, but this creates strong incentives for counterfeiting operations

Engineering Contradiction:
Improveprofit marginVSAvoidcounterfeiting incentive
Core Design Contradiction:
Loss of energyVSObject-affected harmful factors

Solution Approach 1:

The patent transforms the pricing model from a static high-price structure to a dynamic pay-per-use structure. Instead of charging high upfront prices that create counterfeiting incentives, the system implements variable pricing based on actual consumption metrics (pages printed, images processed, etc.), thereby maintaining profitability while reducing the economic incentive for counterfeiting.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent introduces an intermediary tracking system between the consumable and the end user. This intermediary system monitors actual usage through meters, sensors, or software agents, and facilitates automated billing based on measured consumption. This intermediary layer enables precise usage-based charging that would be difficult to implement directly, allowing suppliers to capture value based on actual use rather than relying on high markup pricing.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If suppliers invest in investigator teams and law enforcement operations to combat counterfeiting, then they can analyze and prosecute counterfeit operations, but this approach is costly and often unsuccessful

Engineering Contradiction:
Improvecounterfeit combat effectivenessVSAvoidcombattant cost
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The patent converts the harmful effect of counterfeiting into a beneficial opportunity. Instead of viewing counterfeiters solely as threats to be prosecuted, the system creates a framework where even counterfeit consumables can be tracked and billed. The usage tracking infrastructure designed to prevent counterfeiting also enables the system to charge for usage regardless of whether the consumable is genuine or counterfeit, thereby capturing revenue that would otherwise be lost.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

Solution Approach 2:

The patent implements a self-service tracking and billing system that automatically monitors consumable usage and charges users based on measured consumption without requiring manual investigation or law enforcement intervention. The system uses embedded meters, sensors, or software agents to automatically track usage metrics and generate bills, eliminating the need for costly investigator teams while maintaining effective counterfeiting prevention.

Inventive Principle:
Principle #25Self-service

3Loss of energy

If suppliers use conventional high-profit pricing models, then they can generate revenue from consumable sales, but this damages supplier reputations when counterfeit products enter the market

Engineering Contradiction:
Improverevenue from consumablesVSAvoidsupplier reputation
Core Design Contradiction:
Loss of energyVSReliability

Solution Approach 1:

The patent implements a feedback mechanism where usage data from consumables is continuously transmitted back to the supplier's billing system. This feedback loop enables real-time monitoring of consumption patterns and automated adjustment of charges based on actual usage. The system provides transparency to customers about what they are being charged for, building trust and protecting the supplier's reputation while maintaining revenue streams.

Inventive Principle:
Principle #23Feedback

AI summary

Systems and methods of a pay-for-use pricing plan for consumables associated with a machine. The systems and methods include a machine that can detect a use of a consumable by a consumer. The use can be an installation of the consumable in the machine or an actual use of the consumable in the machine. The machine can detect a charge associated with the use of the consumable. Further, the machine can prompt the consumer for a payment and receive the payment from the consumer. In embodiments, the consumer can have an updatable account associated with the consumable usage. The machine can send an indication of the payment or updated account information to a supplier of the consumable.
