Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual adjustment mechanisms are used in traditional tool holders, then the device complexity is low, but the precision and speed of tool movement are insufficient
Solution Approach 1:
The patent replaces manual mechanical adjustment mechanisms with an electromagnetic driving system consisting of a magnet and electric coil. This substitution eliminates the need for complex mechanical gears and manual operation, while achieving superior precision and speed in tool movement adjustment.
Solution Approach 2:
The patent changes the operational parameters of the tool holder by introducing electrical control through the electric coil and magnet system. This allows for precise control of tool movement parameters (position, speed, direction) through electrical signals, dramatically improving adjustment precision compared to manual mechanisms.
2Productivity
If manual adjustment mechanisms are used in traditional tool holders, then the device structure is simple, but the machining efficiency and speed are reduced
Solution Approach 1:
The patent replaces slow manual mechanical adjustment with an electromagnetic driving system that enables rapid tool movement. The electric coil and magnet combination provides high-speed actuation, significantly improving machining efficiency and productivity while the integrated design keeps the overall structure compact.
3Speed
If gear-driven systems are used for tool adjustment, then mechanical force transmission is achieved, but the instantaneous velocity of tool movement is limited
Solution Approach 1:
The patent replaces gear-driven mechanical transmission with a direct electromagnetic actuation system. The electric coil generates magnetic force that directly moves the tool holder, eliminating the need for intermediate gears and achieving much higher instantaneous velocities in tool movement.
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 electrically-adjustable tool holder significantly improves the precision and speed of tool movement, enabling instantaneous velocities many times greater than manual or gear-driven systems, thereby enhancing machining efficiency and accuracy.
Implementation Method 1
The electric coil can be securely coupled to the tool, and move the tool up or down along the central axis of the handle body in the magnet when electrically stimulated

AI summary
An electrically-adjustable tool holder precisely movable in a straight line within a magnetic field under electrical stimulation includes a handle body, a connecting member, and a driving member. The connecting member has a first end securely coupled to an end ofthe handle body, a second end opposite to the first end, and defines a through hole passing through the first end and the second end. The driving member includes a magnet securely received in the through hole, and an electrical electric coil movably received in the magnet. The electric coil is configured to be securely coupled to the tool, and moves the tool up or down along the central axis of the handle body.
