Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tools for releasing stuck components like a motor vehicle's drive shaft often require multiple tools and can damage other parts during the removal process.
Innovation Solution
A single-tool system with an impact rod, adjustable cable loop, and fastening mechanism that allows secure attachment to the stuck component, enabling efficient release without damaging adjacent parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple tools are used to release stuck components, then the removal can be achieved, but the complexity of the operation increases and other parts may be damaged
Solution Approach 1:
The patent combines multiple previously separate tools into a single integrated tool. The tool integrates an impact mechanism (impact rod with impact weight), a pulling mechanism (cable loop with fastening element), and an adjustment mechanism (adjustment element) into one unified device, eliminating the need for multiple separate tools and reducing operational complexity
Solution Approach 2:
The tool is designed with multi-functionality to handle various stuck components. The adjustable cable loop width and universal fastening element allow the same tool to be applied to different component sizes and types (drive shafts, brake pads, wishbones), making it a universal solution rather than requiring specialized tools for each application
2Productivity
If conventional pulling tools are used, then stuck parts can be removed, but adjacent parts may be damaged during the process
Solution Approach 1:
The tool applies force locally and directly to the stuck component through the cable loop that is precisely positioned around the target part. The impact force is transmitted axially through the fastening element directly to the cable loop, concentrating the pulling action on the intended component without affecting adjacent parts
Solution Approach 2:
The cable loop acts as an intermediary between the impact mechanism and the stuck component. It provides a controlled interface that transmits the impact force while protecting adjacent parts from direct contact with the impact rod or fastening element, preventing collateral damage
3Adaptability or versatility
If a fixed cable loop width is used, then the tool structure is simpler, but the tool cannot adapt to different component sizes
Solution Approach 1:
The cable loop width is made dynamically adjustable rather than fixed. The adjustment element allows the cable loop width to be changed during operation to match different component sizes, while the locking mechanism maintains the selected width during use. This dynamic adaptability enables the tool to handle various component dimensions

Function Achieved in This Case
Enables the safe and efficient removal of stuck parts like drive shafts and other components using a single tool, ensuring minimal damage and universal applicability.
Implementation Method 1
an impact rod (1) on which a movable impact weight (2) is guided... The impact weight (2) can in particular be designed in the shape of a dumbbell so that the user can move the impact weight (2) with a secure manual grip towards a stop (3) at the end of the impact rod (1)

AI summary
A portable tool is provided for releasing a stuck component, such as a drive shaft, diesel injector, or ball joint, using a single manually operable device. The tool comprises an impact rod with a movable impact weight and a stop at one end, and a fastening element at the other end for connecting to an adjustable cable loop. The cable loop secures around the stuck component using a tool-free adjustment mechanism that includes a bent part, a U-shaped bolt with a threaded leg, and a locking screw. A pivotable hook with a spring clip fastener connects the cable loop to the impact rod, allowing axial force transfer when the impact weight is actuated. The tool enables effective and damage-free component release by a single user without requiring additional tools, and is adaptable for use on various components in motor vehicles or other mechanical systems.
