Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If axial attachment device and connection casing are used together for connecting power tool to angle device, then the connection structure is complete and reliable, but the operation process requires excessive positioning and locking effort, making it inconvenient to use
Solution Approach 1:
The patent combines the axial attachment function and angular rotation function into a single integrated connection structure. The connection device integrates the attachment means and angle adjustment means into one unified mechanism, eliminating the need for separate axial attachment device and connection casing operations. This merging allows simultaneous achievement of reliable connection and easy operation through a single integrated action.
Solution Approach 2:
The connection device is designed to perform multiple functions simultaneously: it provides axial attachment, angular rotation, and self-locking capabilities through a single mechanism. The universal design allows the same structure to handle both the securing function and the angle adjustment function, making the device versatile and eliminating the need for separate specialized components for each function.
2Reliability
If separate axial attachment device and connection casing are used, then the connection structure is complete, but the entire operation process takes more time and effort
Solution Approach 1:
The patent merges the axial attachment operation and angular rotation operation into a single integrated operation. By combining these functions in one mechanism, the user completes both attachment and angle adjustment in one action, significantly reducing the time and effort required compared to performing separate operations with separate devices.
Solution Approach 2:
The connection device is pre-configured with the correct geometric relationships and locking mechanisms in place before use. The axial and angular attachment functions are pre-integrated into the structure, so no sequential positioning or adjustment is needed during operation. This preliminary arrangement of functions enables immediate and efficient connection without time-consuming step-by-step operations.
3Reliability
If joint enclosure requires positioning and locking to correct angle, then the angle device is securely locked, but rotating the angle device requires pressing effort
Solution Approach 1:
The patent employs a dynamic locking mechanism that automatically engages and disengages based on the rotation motion itself. During rotation, the locking elements are dynamically actuated by the motion, allowing the angle device to be rotated without continuous pressing force. The locking security is maintained through automatic engagement features that respond to the rotational dynamics, eliminating the need for sustained manual force.
