Solution Overview

Problem

Mortar pumps face challenges with frequent cleaning and insufficient cooling capacity due to heat exchanger soiling from dusty environments, leading to operational inefficiencies.

Innovation Solution

The heat exchanger unit is arranged with vertically aligned air ducts and a removable fan, allowing for easy cleaning and improved airflow, which directs sound emissions downwards, reducing noise and facilitating maintenance. Additionally, a water supply element can enhance cooling and cleaning, and a filter can be used to reduce contamination.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the heat exchanger unit is arranged horizontally with conventional airflow, then the cooling capacity is maintained, but the cleaning frequency increases and maintenance becomes difficult

Engineering Contradiction:
Improvecleaning easeVSAvoidcleaning frequency
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The heat exchanger unit is rotated from a conventional horizontal arrangement to a vertical arrangement, changing the spatial orientation of air ducts from horizontal to vertical. This dimensional change allows cleaning fluid to flow downward along the air ducts, making cleaning easier and more effective while reducing the frequency of maintenance required.

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

Solution Approach 2:

Instead of the conventional horizontal airflow path through the heat exchanger, the invention inverts the arrangement to vertical airflow. This inversion allows gravity to assist in the removal of cleaning fluid and contaminants, simplifying the cleaning process and reducing maintenance time.

Inventive Principle:
Principle #13The other way round (Inversion)

2Ease of repair

If the heat exchanger unit is made accessible for frequent cleaning, then maintenance becomes easier, but the cooling capacity may be compromised

Engineering Contradiction:
Improvemaintenance accessibilityVSAvoidcooling capacity
Core Design Contradiction:
Ease of repairVSReliability

Solution Approach 1:

The vertical arrangement of air ducts creates a compact structure that is both accessible for maintenance and maintains effective cooling. The vertical orientation allows the heat exchanger to be positioned in a space-efficient manner while keeping the airflow path optimized for heat transfer, thus maintaining cooling capacity during frequent maintenance cycles.

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

3Object-affected harmful factors

If the air outlet opening is positioned laterally, then noise is dispersed to surrounding areas, but the cooling efficiency is improved

Engineering Contradiction:
Improvenoise emissionVSAvoidcooling capacity
Core Design Contradiction:
Object-affected harmful factorsVSPower

Solution Approach 1:

The invention converts the potentially harmful noise emission into a beneficial downward-directed airflow. By positioning the air outlet opening at the bottom of the housing, the exhaust noise is directed downward where it is less disturbing, while the vertical airflow path through the heat exchanger maintains effective cooling capacity.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)
