Solution Overview

Problem

Existing systems for monitoring tank parameters, such as level, pressure, and flow, often rely on indicator lights that may not be easily visible to operators, especially when viewing the tank itself, which limits visibility and usability, particularly in night conditions or when the operator is not in close proximity.

Innovation Solution

An in-tank illumination system with sensors and a controller that adjusts lighting based on sensor readings, using LED assemblies to illuminate the tank's interior, allowing external visibility of parameter indications through color, blink patterns, and brightness changes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If indicator lights are mounted on control panels or attached to the sides of tanks, then the system structure remains simple, but the visibility of tank parameters to operators is poor

Engineering Contradiction:
Improvevisibility of tank parametersVSAvoidillumination system structure
Core Design Contradiction:
Illumination intensityVSDevice complexity

Solution Approach 1:

The illumination source is placed inside the tank (nested within the tank structure) rather than externally mounted. This internal placement allows the light to illuminate the tank contents and parameters from within, making them visible through the translucent tank wall, thereby improving visibility without adding external structural complexity

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The translucent tank wall acts as an intermediary medium that transmits the illumination from the internal light source to the external observer. This allows the light to effectively communicate tank parameter information from the interior to the exterior without requiring direct line-of-sight to internal components

Inventive Principle:
Principle #24Intermediary (Mediator)

2Loss of information

If traditional indicator lights are used on control panels, then the system remains simple, but the information provided is limited and less detailed

Engineering Contradiction:
Improvedetail of tank condition informationVSAvoidillumination control system
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The illumination system transitions from static indicator lights to dynamic, multi-color LED illumination that can change color (e.g., green, yellow, red) and blinking patterns based on real-time sensor readings. This dynamic behavior provides detailed information about different tank conditions and parameter ranges, significantly increasing the information content while using programmable control

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

Different colors of illumination are used to represent different tank parameter conditions or ranges. For example, green may indicate normal operating conditions, yellow may indicate warning conditions, and red may indicate critical conditions. This color-coding system provides intuitive, detailed information about tank status without requiring complex displays

Inventive Principle:
Principle #32Color changes

3Ease of operation

If indicator lights are placed on control panels, then installation is straightforward, but operators cannot easily view indications when not in close proximity or during nighttime

Engineering Contradiction:
Improveoperator visibility of tank conditionsVSAvoidillumination energy consumption
Core Design Contradiction:
Ease of operationVSUse of energy by stationary object

Solution Approach 1:

The illumination source can operate in periodic or intermittent modes rather than continuous operation. The controller can activate the illumination only when sensor readings indicate specific conditions that require visual indication, or use periodic blinking patterns to attract operator attention. This reduces overall energy consumption while maintaining effective visibility when needed

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The illumination intensity and duration parameters are dynamically adjusted based on ambient light conditions and detected tank parameter values. The system can increase illumination intensity when nighttime or low-light conditions are detected, and adjust the timing/duration of illumination based on the urgency or nature of the indicated condition, optimizing the balance between visibility and energy consumption

Inventive Principle:
Principle #35Parameter changes
