Solution Overview

Problem

Existing motorized viscous material dispensers, such as caulking guns, lack the ability to efficiently repeat precise dispensing tasks for similar applications, requiring manual adjustment and operation mode switching for consistent material distribution.

Innovation Solution

A motorized viscous material dispenser with a data processing device, memory, and operator-activated switches that allows for a first dispensing mode to record and store operation parameters, enabling a second mode to automatically dispense similar amounts of material by activating the motor based on stored values, using a piston position sensor and pulse generator for precise control.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual operation mode is used for each dispensing task, then the operator can control the dispensing process, but the time and effort required to repeat similar dispensing tasks increases

Engineering Contradiction:

Improveease of operationVSAvoidtime for repeating dispensing tasks

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The system performs preliminary action by recording operation parameters (such as trigger pull duration, piston position, motor speed) during a first dispensing event and storing them in memory. When a similar dispensing task is needed, the pre-recorded parameters are automatically retrieved and applied, eliminating the need for manual re-adjustment and significantly reducing the time and effort required to repeat the dispensing process with consistent results

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system uses copying by creating a digital replica of the operation parameters from a first dispensing event and applying this copy to subsequent dispensing events. The data processing device stores the recorded parameters and automatically retrieves them to replicate the same dispensing characteristics (material amount, dispensing speed, piston movement) without requiring the operator to manually reproduce the same actions

Inventive Principle:

Principle #26Copying

2Manufacturing precision

If operation parameters are recorded and stored for automatic retrieval, then dispensing consistency is improved, but the device complexity increases

Engineering Contradiction:

Improvedispensing precisionVSAvoiddevice complexity

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The data processing device performs multiple functions: it records operation parameters during dispensing, stores them in memory, retrieves stored parameters when needed, and activates the motor according to the retrieved parameters. By consolidating these multiple functions into a single multi-functional device, the patent achieves improved dispensing precision through parameter consistency while minimizing the increase in overall device complexity

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system provides self-service by automatically recording, storing, retrieving, and applying operation parameters without requiring external intervention or complex manual programming. The data processing device autonomously manages the entire parameter lifecycle, from recording during the first dispensing event to automatically applying the stored parameters during subsequent events, thereby achieving precision consistency with minimal added complexity

Inventive Principle:

Principle #25Self-service

3Ease of operation

If a single trigger switch is used for both dispensing modes, then the interface is simplified, but the risk of accidental mode activation increases

Engineering Contradiction:

Improveinterface simplicityVSAvoidrisk of accidental mode activation

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The trigger switch is segmented into two distinct functional zones: a first portion that activates the first dispensing mode (manual operation) and a second portion that activates the second dispensing mode (automatic parameter retrieval). This segmentation allows the single trigger switch to provide both interface simplicity and operational reliability by requiring deliberate activation of each mode through distinct physical actions, thereby preventing accidental mode switching while maintaining a unified interface

Inventive Principle:

Principle #1Segmentation

AI summary

A motorized viscous material dispenser, especially a caulking gun, comprises a motor (27), an operation parameter sensor (51), a data processing device (35), a memory device (37), and at least one operator activated switch (7, 10). The dispenser has a first dispensing mode in which the data processing device (53) records operation parameter values read by the operation parameter sensor (51), when a switch (7) is activated by an operator, and stores at least one operation parameter value in the memory device (37), the motor (27) being activated in accordance with the activation of said switch (7), and a second dispensing mode in which the data processing device (35) activates the motor (27) in accordance with the operation parameter values stored in the memory device (37) when a switch (7) is activated by an operator.
