Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual manipulation of multiple components is used, then device complexity is reduced, but ease of operation deteriorates
Solution Approach 1:
The patent combines multiple independent driving assemblies (main driving assembly, rotation assembly, swing angle assembly) into a single integrated electric stapler system, allowing all operations to be controlled through a unified electronic control interface rather than manual manipulation of separate components
Solution Approach 2:
The patent replaces manual mechanical manipulation with motorized driving assemblies and electronic control systems. The main driving assembly, rotation assembly, and swing angle assembly all use motors and gear assemblies to automate operations that would otherwise require manual handling
2Extent of automation
If integrated motor-driven control is implemented, then ease of operation improves, but device complexity worsens
Solution Approach 1:
The patent divides the automated control system into three independent driving assemblies (main driving assembly, rotation assembly, swing angle assembly), each with its own motor and gear assembly. This segmentation allows for modular design and independent control of different functions while maintaining overall system integration
Solution Approach 2:
The patent implements dynamic control capabilities where each driving assembly can operate independently and be controlled through electronic signals. The system can adapt its operation mode based on surgical needs, allowing flexible automation rather than fixed mechanical linkages
3Productivity
If multiple independent driving assemblies are used, then productivity improves, but device complexity worsens
Solution Approach 1:
The patent merges three independent driving functions into a single integrated device that can perform multiple operations (closure, rotation, swing) simultaneously or in sequence, thereby reducing total surgery time while consolidating the complexity into one coordinated system
Solution Approach 2:
The electric stapler is designed as a multi-functional device where the three driving assemblies enable the instrument to perform various surgical operations (cutting, stapling, rotating, positioning) with a single device, improving productivity by eliminating the need for multiple separate instruments
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
Facilitates single-handed operation, improves efficiency, reduces surgery time, and enhances accuracy by allowing precise control over stapler movements.
Implementation Method 1
The firing gear meshes with the firing driven gear, and the firing driven gear meshes with the firing rack. When the firing motor rotates in a forward direction or in a reverse direction according to a main control instruction, a rotational movement is converted into a rectilinear movement through the firing gear, the firing driven gear and the firing rack
Implementation Method 2
a rotational movement is converted into a rectilinear movement through the firing gear, the firing driven gear and the firing rack

AI summary
An electric anastomat, which comprises an anastomosis assembly and a driving assembly, wherein the driving assembly comprises: a main driving assembly, a rotating assembly, and an angular movement assembly; the main driving assembly is used for driving the anastomosis assembly to close, anastomose, or retract; the rotating assembly is used for driving the anastomosis assembly to rotate 360 degrees; and the angular movement assembly is used for driving the anastomosis assembly to move left and right; the main driving assembly, the rotating assembly, and the angular movement assembly each comprise a motor and a gear assembly, and the main driving assembly, the rotating assembly, and the swing assembly are mutually unaffected by each other during operation; the electric anastomat further comprises a main control chip, an angular movement positioning assembly, and a mount confirmation assembly, wherein the main control chip is cooperates with the angular movement positioning assembly to confirm whether the angular movement assembly is at the zero position, and the main control chip cooperates with the mount confirmation assembly to confirm whether the anastomosis assembly has been correctly mounted. By the provision of an electric assembly, the electric anastomat is more intelligent, and consequently surgical efficiency can be improved, and the difficulty of manipulation by a doctor can be reduced.
