Solution Overview

Problem

The existing logistics methods for transporting liquid dew substances, such as brine, for winter service applications face challenges in achieving the required volume due to truck length constraints, leading to axle overload issues and inefficient use of space.

Innovation Solution

A logistics method involving a separate liquid tank with a liquid connection to the spreading material container, allowing for the use of existing additional tanks as a brine reservoir, which can be easily retrofitted and filled using a pump or pressure relief system, with optimized dimensions and transport elements for efficient handling and storage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If cascade tanks (multiple additional brine tanks) are used to achieve the required brine volume, then the brine volume is sufficient, but the center of gravity shifts causing axle overload

Engineering Contradiction:

Improvebrine volumeVSAvoidaxle load

Core Design Contradiction:

Quantity of substanceVSWeight of moving object

Solution Approach 1:

The invention divides the brine storage function into two segments: the existing additional tank (originally for brine) and the spreading material container (originally for dry salt). By enabling the spreading material container to also store brine, the system segments the storage function across different containers, achieving the required total volume without adding multiple additional tanks that would cause center of gravity issues.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The spreading material container is designed to serve multiple functions: it can store dry salt, store brine, or be used for wet salt spreading. This multi-functionality eliminates the need for separate dedicated brine tanks, reducing the number of additional components while maintaining the required brine volume and avoiding axle overload problems.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Productivity

If the liquid outlet opening is left open for brine discharge, then brine can be discharged, but road salt escapes through the same opening

Engineering Contradiction:

Improvebrine discharge efficiencyVSAvoidroad salt loss

Core Design Contradiction:

ProductivityVSLoss of substance

Solution Approach 1:

A closure element acts as an intermediary between the liquid outlet opening and the contents of the spreading material container. This closure element can be selectively positioned to either allow brine discharge or prevent road salt escape, mediating between the conflicting requirements of discharge efficiency and substance preservation.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The closure element is designed to be movable, allowing the system to dynamically switch between two states: open for brine discharge (high productivity) and closed for preventing salt loss (substance preservation). This dynamic adjustment resolves the contradiction between discharge efficiency and preventing material loss.

Inventive Principle:

Principle #15Dynamics
