Solution Overview

Problem

The management and maintenance of miniapplicators used in crimping operations are inefficient due to the lack of tracking of their operational life and usage, leading to premature replacement or excessive wear.

Innovation Solution

A self-powered cycle detection device is integrated with the crimping assembly, featuring a lever and transducer positioned on a connecting wall, which generates an electrical pulse with each work cycle, allowing for wireless signal transmission and tracking of the tool's operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a detector device is integrated with miniapplicators to track operational life, then maintenance efficiency is improved, but device complexity increases

Engineering Contradiction:
Improvemaintenance efficiencyVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The detector device merges multiple functions into a single integrated unit: the lever is hinged to the casing to detect mechanical movement, the transducer converts mechanical movement into electrical signals, and the wireless transmitter communicates data. This consolidation reduces the number of separate components and simplifies installation while maintaining reliable operational tracking

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The detector device is designed with universal mounting capabilities through fastening supports that can be attached to various miniapplicator types. The lever mechanism can detect different work cycle movements, and the wireless transmitter can communicate with various monitoring systems, making the device adaptable across different crimping machine configurations

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Measurement precision

If the lever is positioned farther from the mounting wall to be driven by the head, then detection accuracy is improved, but the device structure becomes more complex

Engineering Contradiction:
Improvedetection accuracyVSAvoidstructure complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The lever is hinged to the casing at a position distant from the mounting wall, extending into the space beyond the mounting wall. This spatial arrangement allows the lever to be driven by the head's movement in one dimension while maintaining a compact structure in other dimensions. The L-shaped bracket further optimizes space utilization by mounting the transducer on a connecting wall rather than requiring additional depth

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

3Ease of manufacture

If the transducer is positioned on the connecting wall between mounting wall and opposite wall, then ease of manufacture is improved, but measurement precision may be reduced

Engineering Contradiction:
Improveease of manufactureVSAvoidmeasurement precision
Core Design Contradiction:
Ease of manufactureVSMeasurement precision

Solution Approach 1:

The lever acts as an intermediary element that transmits the mechanical movement of the head to the transducer. By positioning the lever's free end to protrude beyond the mounting wall, it can be driven by the head's movement while the transducer remains mounted on the connecting wall. This intermediary arrangement allows the transducer to be positioned in a manufacturally convenient location while still accurately detecting work cycle movements through the lever's mechanical coupling

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A self-powered device (100) detects work cycles of an automatic crimping tool (200) such as a miniapplicator. The device (100) has a casing (110) with a mounting wall (111) for fastening to the main body (210) of the miniapplicator (200). A lever (120) is hinged to the casing (110), and by rotating it applies or releases a force on a transducer (130). The transducer (130) is positioned on a wall (113) connecting the mounting wall (111) and an opposite free wall (112). The lever (120) protrudes beyond the mounting wall (111) in order to be pressed by a head (232) of a driving structure (230) of the miniapplicator (200), so as to be rotated. The transducer (130), when pressed, generates an electrical pulse by means of an energy harvesting process, and powers a transmission module. This transmits a wireless signal in response to the electrical pulse, allowing the work cycles to be monitored.
