Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a conventional cup is used, then the basic function of holding liquid is achieved, but the ability to intuitively measure water volume and temperature is lost

Engineering Contradiction:
Improveliquid level measurementVSAvoidcup structure
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The electronic module including laser probe, transparent shielding sheet, and control circuit is nested within the cup cover structure. The laser probe is positioned inside the cup cover pointing downward, with the transparent shielding sheet covering the probe, creating a compact integrated measurement system within the existing cup architecture.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The patent replaces traditional mechanical measurement methods (such as physical float indicators or scale markings) with an optical measurement system using laser probes and light scattering detection. This substitution enables more precise and automated measurement of liquid level and properties without complex mechanical moving parts.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Measurement precision

If an electronic module with laser detection unit is added to the cup cover, then accurate detection of liquid conditions is achieved, but the device complexity increases

Engineering Contradiction:
Improveliquid composition detectionVSAvoidelectronic module structure
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The laser detection unit serves multiple functions: it measures liquid level through light scattering, detects liquid composition by analyzing spectral characteristics, and can identify temperature conditions. This multi-functionality reduces the need for separate sensing systems for each parameter, thereby managing complexity while enhancing measurement capabilities.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The transparent shielding sheet acts as an intermediary element that both protects the laser probe and facilitates the optical measurement process. It allows laser light to pass through while scattering the light to enhance detection sensitivity, and its transparency enables the laser to interact with the liquid without being blocked by the protective covering.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Measurement precision

If laser light is emitted directly into the cup body, then detection capability is improved, but sufficient feedback photons cannot be ensured

Engineering Contradiction:
Improvedetection accuracyVSAvoidfeedback photons
Core Design Contradiction:
Measurement precisionVSLoss of information

Solution Approach 1:

The patent employs light scattering (an optical analog to vibration/dispersion) by using the transparent shielding sheet to scatter the laser light in multiple directions. This scattering effect increases the interaction between light and liquid particles, enhancing the backscattered signal and ensuring sufficient feedback photons reach the detector for accurate measurement.

Inventive Principle:
Principle #18Mechanical vibration

4Reliability

If the laser probe is covered by a transparent shielding sheet, then the probe is protected, but light transmission may be affected

Engineering Contradiction:
Improveprobe protectionVSAvoidlaser light transmission
Core Design Contradiction:
ReliabilityVSIllumination intensity

Solution Approach 1:

The transparent shielding sheet serves as an intermediary that balances protection and light transmission. Its transparency allows sufficient laser light to pass through to the liquid, while its physical presence protects the delicate laser probe from direct contact with the liquid and potential damage. The scattering effect further enhances detection by increasing light-liquid interaction.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

Disclosed is an intelligent measurement cup, comprising a cup body and a cup cover, which covers the cup body and has an electronic module provided therein. The electronic module comprises a battery, a main control circuit board electrically connected to the battery, and a laser detection unit electrically connected to the main control circuit board. The laser detection unit comprises a laser probe and a transparent shielding sheet which covers the laser probe. The laser probe is arranged at a side facing toward the cup body. A through hole is formed in the cup cover in a manner of corresponding to the laser probe so as to allow light of the laser probe to pass through. A laser emitted from the laser probe penetrates the shielding sheet and is then incident in the cup body in a scattered manner, so as to ensure that sufficient feedback photons are formed. The spectra reflected back through different emission media are different, therefore, the conditions of a liquid, conditions comprising the remaining amount, the type, whether the liquid has deteriorated, etc., in the cup body can be accurately detected.
