Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pressing tools require manual adjustment of the transport device to match the size of ferrules, which is inconvenient and time-consuming.
Innovation Solution
A pressing tool with a holding-down device that automatically sets the transport device to the correct size using a spring-retaining mechanism, allowing for automatic adjustment of the transport device to accommodate ferrules of different diameters, and a strip guide to prevent ferrule loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual adjustment of the transport device is used to match ferrule size, then the transport device can be set to the correct size, but the operation becomes inconvenient and time-consuming
Solution Approach 1:
The transport device automatically adjusts to the correct size through a spring mechanism that self-regulates based on the ferrule diameter. The spring-loaded transport lever automatically positions itself to match different ferrule sizes without requiring manual intervention, making the device serve itself rather than requiring operator adjustment.
Solution Approach 2:
The spring constant of the spring element is specifically selected to enable automatic adaptation to different ferrule diameters. By changing the physical parameter of the spring (its constant), the system achieves automatic size matching across different ferrule specifications without manual reconfiguration.
2Adaptability or versatility
If the transport device is made adjustable for different ferrule sizes, then versatility is improved, but device complexity increases
Solution Approach 1:
The spring mechanism serves multiple functions simultaneously: it provides the prestressing force for movement, automatically adjusts the transport lever position for different sizes, and maintains consistent contact pressure. This single universal mechanism replaces what would otherwise require multiple adjustment components, achieving versatility without proportional complexity increase.
Solution Approach 2:
The transport device transitions from a static, manually-adjusted structure to a dynamic system where the spring continuously adapts the transport lever position based on the ferrule diameter. This dynamic adaptation allows the device to handle various ferrule sizes automatically, achieving versatility through motion and elastic deformation rather than complex mechanical adjustments.
3Extent of automation
If spring prestressing is used to move the transport device, then automatic movement is achieved, but control precision may be affected
Solution Approach 1:
The spring mechanism creates a natural feedback system where the spring force automatically adjusts based on the resistance encountered during transport lever movement. As the lever encounters different ferrule diameters, the spring compresses or extends accordingly, providing continuous feedback that maintains precise positioning without requiring external control systems.

AI summary
A pressing tool has two grips movable relative to one another, a crimping unit with a crimping drum arranged in a tool head of the pressing tool and having at least one crimping die and a depository for storing a strip of ferrules connected to one another as a belt. The tool also includes a transport device movable in a prestressed manner toward the crimping drum to transport the ferrule strip from the depository toward the crimping drum. The transport device has a transport plate and a transport lever pivotably arranged and sprung relative to the transport plate. The transport lever has an attachment close to the crimping drum that can be pressed in between adjacent ferrules there arranged. The attachment is arranged between the transport device and a support surface of a head cap. There is a holding-down device which is spring supported on the support surface and which presses the transport plate against the transport lever.
