Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a reciprocating ratchet head is used to pull the wrench back and forth in a small range, then the space requirement is reduced, but the operation becomes constrained to a fixed direction and angle
Solution Approach 1:
The main body is made rotatable relative to the grip body through a rotating structure, allowing the operation direction to be dynamically adjusted while maintaining the compact reciprocating ratchet head design. This enables the tool to adapt to different angles and directions without requiring large space
Solution Approach 2:
The driving tool integrates both reciprocating ratchet head functionality and press-type driving capability within a single structure. The main body can rotate to accommodate different operation directions, making the tool universally applicable to various fastening scenarios while maintaining compact dimensions
2Productivity
If a press-type driving tool is used to drive the tool head to rotate through pressing, then the screwing speed is improved, but the user must follow a fixed pressing direction which is inconvenient for special angles
Solution Approach 1:
The main body is designed to rotate relative to the grip body, allowing the pressing direction to be dynamically adjusted to match different fastening angles and user positions. This maintains the high-speed press-type driving capability while improving operational convenience
Solution Approach 2:
The rotating structure between the main body and grip body adds a rotational degree of freedom, allowing the tool to operate in multiple directions and angles while maintaining the efficient press-type driving mechanism
3Adaptability or versatility
If the main body is made rotatable relative to the grip body, then the operation angle and direction flexibility is improved, but the device complexity increases
Solution Approach 1:
The driving tool is divided into distinct modules: grip body, main body, and driving assembly. The rotating structure connects these segments, allowing independent optimization of each part while achieving overall flexibility. This modular segmentation manages complexity by creating clear functional boundaries
4Adaptability or versatility
If conventional wrench operation is used requiring angle readjustment, then the operation direction is flexible, but the process is time-consuming and inefficient
Solution Approach 1:
The rotatable main body allows continuous adjustment of the operation angle without requiring complete removal and repositioning of the tool head. Users can dynamically adjust the angle during operation, eliminating time-consuming readjustment cycles while maintaining directional flexibility
Solution Approach 2:
The rotating structure enables continuous adjustment of the operation angle during the fastening process, allowing users to maintain productive action without interruption for angle readjustment. The tool remains engaged with the fastener while the angle is adjusted

Implementation Method 1
the first driving member has a first driving toothed portion which is annular, the second driving member has a second driving toothed portion which is annular... the second transmitting toothed portion is meshed with the second driving toothed portion of the second driving member
Implementation Method 2
the first driving member and the second driving member are rotatably and coaxially arranged in the grip body and the first driving member is connected to the second driving member via the unidirectional rotating structure, when the first driving member rotates in a rotation direction, the second driving member can be driven to rotate via the unidirectional rotating structure, when the first driving member rotates in a direction counter to the rotation direction, the second driving member is not driven to rotate synchronously
Implementation Method 3
the press handle includes a driven toothed row, and the driven toothed row is meshed with the first driving toothed portion of the first driving member so as to drive the first driving member to rotate through a movement of the press handle
Implementation Method 4
the first transmitting toothed portion is meshed with the driven toothed portion of the at least one driven member, and the second transmitting toothed portion is meshed with the second driving toothed portion of the second driving member
