Solution Overview

Problem

Pointing brickwork by hand or using traditional apparatus is slow and time-consuming, especially as the scale of the brickwork increases, leading to increased costs and inefficiencies.

Innovation Solution

A pointing device that includes a filling nozzle, support, movement means, control unit, and sensor, which work together to efficiently and accurately fill pointing spaces without physical interaction with the brickwork, using a cement-based pointing substance and allowing for real-time adjustments and precise application of pointing material.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If pointing brickwork is performed by hand or using traditional apparatus, then the brickwork can be pointed, but the process is slow and time-consuming

Engineering Contradiction:
Improvepointing speedVSAvoidtime required for pointing
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent replaces manual mechanical pointing operations with an automated dispensing system that uses a nozzle to apply pointing material. The control unit automates the positioning and material application, substituting human labor with a mechanical automation system that operates continuously at higher speeds.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system incorporates sensors that automatically detect the position and characteristics of brickwork elements, allowing the device to self-adjust and self-position without manual intervention. The control unit processes sensor data to automatically control the dispensing operation, making the system self-sufficient.

Inventive Principle:
Principle #25Self-service

2Object-affected harmful factors

If traditional pointing apparatus is used, then pointing can be performed, but physical interaction may damage the brickwork

Engineering Contradiction:
Improvedamage to brickworkVSAvoidphysical contact requirement
Core Design Contradiction:
Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The patent introduces a nozzle as an intermediary component that applies pointing material without direct physical contact between the operator and the brickwork. The pointing material itself serves as a mediator that fills gaps without requiring forceful manipulation of the bricks or stones.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system replaces manual physical interaction with automated positioning mechanisms. The movement means and control unit precisely position the nozzle without requiring operators to physically handle or touch the brickwork, eliminating the risk of accidental damage from human contact.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Strength

If cement-based pointing substance is used, then strong pointing material is achieved, but clogging in traditional apparatus occurs

Engineering Contradiction:
Improvepointing material strengthVSAvoidclogging risk
Core Design Contradiction:
StrengthVSReliability

Solution Approach 1:

The patent replaces traditional mechanical pointing tools with a controlled dispensing system that uses air pressure or pump mechanisms to deliver cement-based material through a nozzle. This substitution eliminates the mechanical components (such as trowels or forced injection systems) that were prone to clogging, while maintaining reliable material delivery.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
