Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Single-strike-action auto hammers struggle with driving large nails into hard materials, often bending or damaging the tool, and existing tools lack versatility for use in confined spaces and varying environments.
Innovation Solution
A compact auto hammer design with a pivotable striking device, adjustable angle, and a transmission mechanism for linear reciprocating motion, featuring a soft grip and head assembly for comfort and precision, allowing operation between perpendicular surfaces with a small distance from the striking rod to the intersecting line, facilitating use in narrow spaces and near base walls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the distance from the central axis of the striking rod to the intersecting line is reduced to enable use in narrow spaces, then the adaptability to confined spaces is improved, but the structural complexity of the housing and striking device increases
Solution Approach 1:
The striking device is made pivotable relative to the grip portion, allowing the angle between the central axis of the grip and the central axis of the striking rod to be adjusted between 60° and 180°. This dynamic adjustment capability enables the tool to adapt to different working circumstances and confined spaces without requiring multiple specialized tools, thereby improving adaptability while maintaining reasonable structural complexity through a single adjustable mechanism.
2Productivity
If the auto hammer is designed for continuous-strike-action to drive large nails into hard materials, then the productivity is improved, but the reliability of the tool decreases due to increased risk of damage
Solution Approach 1:
The striking device is designed to be pivotable relative to the grip portion, enabling the user to adjust the angle between the central axis of the grip and the central axis of the striking rod between 60° and 180°. This dynamic adjustment capability allows the tool to adapt to different working circumstances and confined spaces, enhancing versatility while maintaining continuous-strike-action functionality for driving large nails into hard materials.
3Adaptability or versatility
If the distance from the striking rod to the base wall is reduced for use near walls, then the adaptability to narrow spaces is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The striking device is designed to be pivotable relative to the grip portion, allowing the angle between the central axis of the grip and the central axis of the striking rod to be adjusted between 60° and 180°. This dynamic adjustment capability enables the tool to adapt to different working circumstances and confined spaces, including areas near base walls, while avoiding the need for extremely tight manufacturing tolerances through geometric flexibility.

AI summary
An auto hammer having a housing having a grip portion defining a central axis and a head assembly including a striking device which has a striking rod defining a central axis. The striking device is pivotable relative to the grip portion and the angle between the central axis of the grip and the central axis of the striking rod can range between 60° and 180°. The auto hammer thus provides a pivotable striking device and is thereby suitable for different working circumstances.
