Solution Overview

Problem

Existing methods for measuring container capacity, such as those using laser devices, require electronic components to be inserted into the container, violating safety regulations and introducing uncertainty in measurements, especially when dealing with hazardous substances like fuels or explosive vapors.

Innovation Solution

An apparatus with a laser measurement device and optic deflector positioned outside the container, using a bearing shaft with a through hole to direct the laser beam internally, allowing for high-resolution scanning without electronic components inside the container, thus adhering to safety regulations and minimizing measurement uncertainty.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If electronic laser measurement devices are inserted into the container, then measurement capability is achieved, but safety regulations are violated and measurement uncertainty increases

Engineering Contradiction:
Improvemeasurement uncertaintyVSAvoidsafety compliance
Core Design Contradiction:
Measurement precisionVSReliability

Solution Approach 1:

The measurement system is segmented into two parts: the electronic laser measurement device remains outside the container, while only a passive optical deflector is inserted inside. This segmentation allows the electronic components to stay in the safe external environment while the optical component performs measurements through the container interior, thus maintaining both safety compliance and measurement precision.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A passive optical deflector serves as an intermediary element that is inserted into the container. This deflector redirects the laser beam without containing any electronic components, acting as a mediator between the external electronic measurement device and the internal measurement space. The intermediary approach enables measurements inside hazardous containers while violating no safety regulations.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If the laser measurement device is moved to scan the container, then measurement coverage is improved, but measurement uncertainty increases

Engineering Contradiction:
Improvemeasurement coverageVSAvoidmeasurement uncertainty
Core Design Contradiction:
Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The measurement approach transitions from static single-point measurements to dynamic multi-dimensional scanning. The optical deflector rotates around the container's vertical axis and simultaneously moves vertically, creating a two-dimensional scanning pattern that comprehensively covers the entire container interior. This dimensional expansion enables complete measurement coverage while maintaining precision through the stability of the external electronic device.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
