Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gas-spring type driving tools face durability issues and operation failures due to complex configurations and interference states, particularly when nail jamming occurs, leading to restricted load application and engagement problems.
Innovation Solution
A driving tool with a piston-driven mechanism featuring a lift mechanism that includes a rotation shaft, wheel, and engagement portions, where the wheel can displace radially to accommodate interference states and external forces, using a displacement allowing mechanism to overcome engagement issues and a displacement restricting mechanism to maintain stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the lift mechanism includes a displaceable engagement portion to accommodate nail jamming, then the adaptability to interference states is improved, but the device complexity increases and durability decreases
Solution Approach 1:
The wheel is designed to be displaceable in the radial direction of the rotation shaft, allowing dynamic adjustment of the engagement portions' positions. This dynamic capability enables the lift mechanism to adapt to interference states such as nail jamming without requiring complex reconfiguration, thereby improving adaptability while maintaining relatively simple structure.
Solution Approach 2:
The radial position of the wheel is changed as a key parameter to accommodate interference states. By allowing the wheel to move radially, the engagement portions can be repositioned relative to the driver, enabling the system to handle various interference conditions without increasing structural complexity.
2Adaptability or versatility
If the engagement portion is made displaceable to handle nail jamming, then the adaptability to interference states is improved, but the durability of the lift mechanism decreases
Solution Approach 1:
The displaceable wheel design allows the engagement portions to dynamically adjust their radial position, which helps in handling nail jamming situations. This dynamic adjustment capability improves adaptability while the controlled displacement mechanism maintains durability by preventing excessive or uncontrolled movements that could damage the lift mechanism.
3Stability of the object's composition
If the wheel is restricted from radial displacement to maintain stability, then the stability of the lift mechanism is improved, but the ability to accommodate interference states is reduced
Solution Approach 1:
The wheel is designed with controlled displaceability in the radial direction, allowing it to remain stable during normal operation while being able to adjust when interference states occur. This dynamic design enables the system to maintain stability under normal conditions and adapt to interference states such as nail jamming when necessary.
Solution Approach 2:
The radial position of the wheel is changed as a control parameter to balance stability and adaptability. The wheel is restricted from radial displacement during normal operation to maintain stability, but can be displaced when interference states are detected or occur, thereby accommodating various operating conditions.
4Device complexity
If the engagement portion is fixed to simplify the structure, then the device complexity is reduced, but the ability to handle nail jamming is lost
Solution Approach 1:
The wheel is designed to be displaceable in the radial direction, providing a simple yet effective mechanism to handle nail jamming situations. This dynamic capability allows the engagement portions to adjust their positions to accommodate interference states without requiring complex reconfiguration mechanisms, thereby maintaining structural simplicity while improving adaptability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The configuration simplifies the lift mechanism, enhances durability, and reliably avoids operation failures by allowing radial displacement of the wheel to address interference and external forces, ensuring proper engagement and stable operation.
Implementation Method 1
a piston that moves in a driving direction by a pressure of gas
Implementation Method 2
a wheel that rotates integrally with the rotation shaft and rotates around the rotation shaft, and a plurality of engagement portions that are arranged along an outer periphery of the wheel. Each of the plurality of engagement portions is configured to engage a corresponding engaged portion

AI summary
A driving tool comprises a displacement allowing mechanism that allows a wheel to be displaced in a radial direction of a rotation shaft. The driving tool further comprises a displacement restricting mechanism that restricts the wheel from being displaced in the radial direction of the rotation shaft. When a driver is to start being moved upwards by an engagement of a first engagement portion with an engaged portion by rotation of the wheel, a displacement restriction state of the wheel caused by the displacement restricting mechanism is released, allowing an entirety of the wheel to be displaceable in the radial direction of the rotation shaft due to the displacement allowing mechanism.
