Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If robotic arms are shipped as complete units with fixed joint positions, then manufacturing and quality control are simplified, but adaptability to different consumer demands is reduced
Solution Approach 1:
The robotic arm is divided into modular joint units that can be independently manufactured and then assembled in different configurations. Each joint includes standardized fixing elements that enable easy connection and disconnection, allowing the robotic arm to be reconfigured for different applications without redesigning the entire system.
Solution Approach 2:
The joint design incorporates rotatable fixing elements that can be dynamically adjusted during assembly. The fixing elements include rotating portions that can be turned to different positions, allowing flexible connection orientations and enabling the robotic arm to adapt to various configuration requirements.
2Adaptability or versatility
If joint positions and connections are fixed in complete robotic arms, then structural stability is maintained, but flexibility in specification selection is limited
Solution Approach 1:
The joints are pre-equipped with fixing elements in specific initial positions during manufacturing. These pre-positioned fixing elements ensure stable connections when joints are assembled, while still allowing reconfiguration by rotating the fixing elements to different positions if specification changes are needed.
Solution Approach 2:
The connection parameters of the joints can be changed by rotating the fixing elements to different angular positions. This allows the same physical joint to achieve different connection configurations, providing specification flexibility while maintaining reliable connections through standardized fixing mechanisms.
3Productivity
If manufacturers produce standardized complete robotic arms, then production efficiency is improved, but response time to diverse consumer demands increases
Solution Approach 1:
By segmenting the robotic arm into standardized joint modules that can be manufactured independently and assembled quickly, manufacturers can produce joints in high volumes efficiently. When orders come in, these pre-manufactured joints can be rapidly assembled into different robotic arm configurations, significantly reducing response time compared to building complete arms from scratch.
Solution Approach 2:
The standardized joint design with universal fixing elements allows the same joint components to serve multiple configuration purposes. A single batch of manufactured joints can be used to fulfill various customer orders with different specifications, enabling manufacturers to respond quickly to diverse demands without producing different custom parts for each order.

AI summary
A joint includes a joint housing, a first fixing element and a second fixing element. The first fixing element is rotatably connected to the joint housing and has a first fixing portion. The second fixing element is fixed to the joint housing and has a second fixing portion. The first fixing portion and the second fixing portion respectively have matching structures.
