Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If traditional radon monitoring instruments are used, then radon concentration can be measured, but the system becomes expensive and unstable

Engineering Contradiction:

Solution Approach 1:

The patent replaces expensive traditional radon monitoring instruments with a low-cost detection device based on the alpha spectrum of radon decay. The device uses a simple ionization chamber and alpha particle detector instead of complex spectroscopic equipment, achieving accurate radon measurement at a fraction of the cost while maintaining reliability through simplified design that eliminates instability issues of traditional instruments.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The patent changes the measurement parameter from complex spectroscopic analysis to alpha particle counting over time. By measuring the alpha spectrum and integrating counts over a period, the system achieves stable and reliable radon concentration measurement without requiring expensive instruments, thus resolving the contradiction between measurement precision and system reliability.

Inventive Principle:
Principle #35Parameter changes

2Measurement precision

If traditional radon monitoring instruments are used, then radon concentration can be measured, but the sensitivity is very low and measurement time is very long

Engineering Contradiction:
Improveradon concentration measurement accuracyVSAvoidmeasurement time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent implements continuous radon measurement by continuously counting alpha particles in the ionization chamber. The detection device operates continuously to accumulate statistics and generate real-time radon concentration data, eliminating the need for long intermittent measurement cycles. This continuous action provides both high sensitivity and rapid measurement results simultaneously.

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

The patent replaces slow mechanical measurement processes with electronic alpha particle detection and signal processing. By using electronic counting and spectrum analysis instead of traditional mechanical or chemical measurement methods, the system achieves high sensitivity and fast measurement response, resolving the contradiction between measurement precision and measurement time.

Inventive Principle:

3Reliability

If radon monitoring service is provided continuously, then real-time radon concentration can be monitored, but the cost becomes very high

Engineering Contradiction:
Improvereal-time monitoring capabilityVSAvoidservice cost
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The patent implements a self-service billing model where users are charged based on their actual radon monitoring needs and behavior patterns. The system analyzes user ventilation actions and radon concentration data to determine appropriate billing, allowing users to benefit from real-time monitoring while paying only for the service they actually utilize, thus reducing overall service costs while maintaining reliability.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent changes the billing parameter from fixed continuous service charges to variable charges based on user behavior patterns and radon concentration levels. By analyzing ventilation actions and monitoring data, the system dynamically adjusts billing to reflect actual service needs, making continuous monitoring affordable while maintaining real-time capability and reliability.

Inventive Principle:
Principle #35Parameter changes

4Measurement precision

If users do not take ventilation actions, then radon concentration remains high, but users lack motivation to reduce radon levels

Engineering Contradiction:
Improveradon concentration monitoring accuracyVSAvoiduser motivation to reduce radon
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The patent implements a feedback mechanism where the system monitors user ventilation actions and radon concentration levels, then provides feedback to users through the billing system. By linking billing to ventilation behavior patterns, the system motivates users to take ventilation actions to reduce radon levels, as their actions directly influence their service costs. This feedback loop transforms passive monitoring into active user engagement.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent changes the operational parameter from static monitoring to dynamic interaction between users and the system. By analyzing ventilation action patterns and adjusting billing accordingly, the system creates an incentive structure that motivates users to actively reduce radon levels. This parameter change from passive to active operation significantly improves ease of operation by aligning user interests with radon reduction goals.
