Solution Overview

Problem

Existing propellant holders and setting tools lack user-friendly mechanisms to determine the remaining number of propellant charges, requiring users to remove the container from a dispenser to assess the supply level, which is inefficient.

Innovation Solution

Incorporating a data storage identification unit in the propellant holder and a display with a data communication interface in the setting tool, allowing electronic readout and display of propellant supply levels without the need for physical removal, using EEPROM, magnetic strips, or transponder antennas for data exchange.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If a box-shaped magazine with increased length is used to hold a large number of propellant charges, then the quantity of propellant charges is improved, but the user cannot determine the number of remaining charges without removing the magazine

Engineering Contradiction:
Improvenumber of propellant chargesVSAvoidinformation about remaining charges
Core Design Contradiction:
Quantity of substanceVSLoss of information

Solution Approach 1:

The patent implements a feedback mechanism by providing a display device that continuously shows the number of remaining propellant charges in the magazine. A sensor detects the position of the magazine strip and communicates this information to the display, allowing users to monitor propellant levels without removing the magazine, thus resolving the information loss problem while maintaining high capacity

Inventive Principle:
Principle #23Feedback

2Productivity

If the magazine strip is made longer to increase the number of propellant charges, then the productivity is improved, but the device complexity increases

Engineering Contradiction:
Improvenumber of setting processesVSAvoidmagazine strip structure
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent replaces complex mechanical indicators with an electronic sensing and display system. Instead of using mechanical mechanisms to indicate propellant levels, the system uses sensors to detect magazine position and electronically displays the remaining charge count, simplifying the overall device structure while enabling longer magazine strips for increased productivity

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

3Measurement precision

If the propellant holder is removed from the receptacle to check the supply level, then the measurement precision is improved, but the loss of time increases

Engineering Contradiction:
Improvepropellant supply levelVSAvoidtime for removal and checking
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The system provides self-service monitoring by automatically detecting the propellant supply level through sensors and displaying the information without requiring user intervention to remove or manipulate the propellant holder. The display continuously shows the remaining charges, allowing users to obtain precise supply level information instantly without time loss

Inventive Principle:
Principle #25Self-service
