Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional cups are used, then the structure is simple and easy to manufacture, but the ability to measure water volume and detect liquid conditions is lacking
Solution Approach 1:
The patent combines multiple detection functions (laser detection unit for volume measurement, temperature detection unit, and liquid quality detection) into an integrated electronic module housed within the cup cover. This merging of detection systems allows the cup to simultaneously measure water volume, temperature, and liquid quality without requiring separate devices, thereby improving measurement precision while managing device complexity through functional integration.
Solution Approach 2:
The patent introduces an electronic module as an intermediary system that bridges the gap between simple cup structure and advanced detection capabilities. The electronic module processes signals from various sensors and communicates liquid condition data to users, enabling accurate liquid condition detection while maintaining a relatively simple overall cup structure that users can easily understand and operate.
2Measurement precision
If laser detection unit is added to detect liquid conditions, then detection accuracy improves, but device complexity increases
Solution Approach 1:
The laser detection unit is designed to perform multiple functions: measuring liquid level volume, detecting liquid composition, and identifying liquid quality. By making this single detection component multi-functional, the patent improves measurement precision across multiple parameters without proportionally increasing device complexity, as one component serves several detection purposes simultaneously.
Solution Approach 2:
The laser detection unit operates with feedback mechanisms where the system emits laser light, detects the reflected or transmitted light patterns, and processes this information to determine liquid conditions. The feedback loop allows for accurate real-time detection of liquid level and composition, improving measurement precision while the automated feedback processing reduces the need for complex manual measurement systems.
3Measurement precision
If transparent shielding sheet with scattering effect is used, then sufficient feedback photons are ensured, but manufacturing precision requirements increase
Solution Approach 1:
The transparent shielding sheet utilizes light scattering properties as a key parameter to ensure sufficient feedback photons reach the detector. By carefully selecting materials with appropriate scattering coefficients and controlling the sheet's optical parameters, the system ensures adequate photon feedback for accurate detection. This parameter-based approach balances manufacturing precision requirements with detection effectiveness, as scattering properties can be controlled through material selection rather than requiring extremely tight dimensional tolerances.

Function Achieved in This Case
Enables accurate detection of liquid conditions, including volume, type, and spoilage, by utilizing the scattering effect of the transparent shielding sheet to ensure sufficient feedback photons, allowing for precise analysis of spectra reflected by different media.
Implementation Method 1
utilizes a scattering effect of the transparent shielding sheet on the light of the laser probe to enable the light to be emitted into the cup body in the scattering mode, sufficient feedback photons are ensured to be formed
Implementation Method 2
laser light emitted by the laser probe passes through the shielding sheet and then is emitted into the cup body
Implementation Method 3
spectra reflected by different emitting media are different, so that conditions of a liquid in the cup body can be accurately detected

AI summary
An intelligent measurement cup comprises a cup body and a cup cover with an electronic module. 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 positioned to face the cup body. The cup cover has a corresponding through hole aligned with the laser probe to allow its light to pass through. The emitted laser is configured to penetrate the shielding sheet and scatter into the cup body, to thereby generate sufficient feedback photons. 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.
