Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a standard impact rotary tool is used, then the tool structure remains simple and easy to operate, but the tool cannot perform various types of machining work that require different rotational axis orientations
Solution Approach 1:
The attachment device enables a single impact rotary tool to perform multiple machining operations by providing different output shaft orientations (horizontal, vertical, angled) through interchangeable attachment units, making the tool system universal for various machining tasks
Solution Approach 2:
The attachment device is designed to be mounted on the output shaft of the impact rotary tool, with the input shaft receiving the tool's output and the output shaft providing the transformed rotational force, creating a nested configuration where the attachment unit integrates with the existing tool structure
2Adaptability or versatility
If an attachment device with driving force conversion mechanism is added, then the tool can perform machining tasks with different rotational axis orientations, but the device complexity increases
Solution Approach 1:
The input shaft acts as an intermediary component that receives rotational driving force from the impact rotary tool's output shaft and transmits it to the output shaft, enabling the conversion of rotational axis orientation while maintaining a relatively simple mechanical structure
Solution Approach 2:
The attachment device changes the dimensional orientation of the rotational axis by providing output shafts in different spatial orientations (horizontal, vertical, angled) relative to the input shaft, enabling machining operations in multiple directions without complex mechanisms

AI summary
The problem to be overcome by the present disclosure is to provide an impact rotary tool attachment and tool system, both of which are designed to allow the user to have various types of machining work done more easily. An impact rotary tool attachment (7; 7a; 7b; 7c) according to the present disclosure includes an input shaft (71), a second output shaft (73), and a driving force conversion mechanism (9; 9a; 9b). To the input shaft (71), rotational driving force is transmitted from a first output shaft (450) of an impact rotary tool (1). To the second output shaft (73), the rotational driving force is transmitted from the input shaft (71). The driving force conversion mechanism (9; 9a; 9b) performs, when the rotational driving force is transmitted from the input shaft (71) to the second output shaft (73), at least one of: translating a rotational axis of rotation produced by the rotational driving force; changing an angle defined by the rotational axis; and converting the rotational driving force into thrust driving force applied along the rotational axis.
