Hydraulic Tool Head Retaining Rod and Curved Tool Carrier Layout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing device heads for hydraulically actuated tools face challenges in the design of the second tool carrier for effective guidance and removal, particularly in accommodating varying tool sizes and preventing damage during assembly and storage.
Innovation Solution
The second tool carrier is designed as an elongated rectangle with vertical edges and arcuate shorter edges, integrated with the piston skirt, allowing for adjustable connection to the piston shaft and protection from external damage, along with a telescopic holding rod for improved maneuverability and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the second tool carrier is designed as an elongated rectangle with arcuate shorter edges, then the guidance and removal of tools is improved, but the device complexity increases
Solution Approach 1:
The shorter edges of the second tool carrier are designed with arcuate lines having a common radius related to the hydraulic piston axis. This curved geometry enables the tool carrier to be guided along arcuate paths during operation and facilitates easier removal by allowing rotational movement during extraction, directly resolving the guidance and removal difficulties
2Object-affected harmful factors
If the piston shaft is completely accommodated in the cylindrical design, then protection from external damage is improved, but the ease of assembly and disassembly worsens
Solution Approach 1:
The device is segmented into distinct components: the cylindrical design that remains fixed in the device head, and the tool carrier with piston shaft that can be detached. The tool carrier is designed to be removable through the device mouth, allowing assembly and disassembly while the cylindrical design provides protection when assembled
Solution Approach 2:
The device mouth serves as an intermediary passage that enables the tool carrier to be inserted and removed from the device head. This opening allows access to the internal components for assembly and disassembly while maintaining protection during operation
3Manufacturing precision
If the device head is designed integrally with counterholder and cylindrical design, then manufacturing precision is improved, but the adaptability for different tool configurations worsens
Solution Approach 1:
While the device head is constructed integrally for manufacturing precision, the tool carrier is designed as a separate, interchangeable component. This segmentation allows different tool carriers to be used with the same device head, providing adaptability for different tool configurations while maintaining the precision benefits of integral construction

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration enhances the guidance and removal of tools, reduces the risk of damage, and allows for more efficient assembly and disassembly, while enabling overhead use and reduced manual handling of the device head.

AI summary
The invention relates to a device head (1) of a hydraulically actuatable tool (W), comprising an opposing holder (2) which is integrally formed on the device head (1) and which has a receiving means for a first tool (3), and comprising a second tool (5) that can be moved towards the opposing holder (2) by means of a hydraulic piston (6), wherein a cylindrical formation (4) also formed integrally with the device head (1) is provided relative to the hydraulic piston (6). In order to develop a further improved device head of this type so that it can be more easily handled, it is proposed that the device head (1) also has an integrally formed toothing recess (8) for the angular fixed, but also changeable, arrangement of a retaining rod (9).
