Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple gripper blocks are connected using traditional fluidic connection methods, then fluid transmission between gripper blocks is achieved, but the system becomes complex and requires external supply lines increasing interference contours
Solution Approach 1:
The intermediate piece merges the fluidic connection function with the mechanical coupling function. By integrating the fluidic channels directly into the intermediate piece that also serves as the coupling element, the patent eliminates the need for separate external supply lines and reduces system complexity while ensuring reliable fluid transmission between gripper blocks.
Solution Approach 2:
The intermediate piece acts as an intermediary component that facilitates both mechanical connection and fluid transmission between adjacent gripper blocks. This mediator component embeds the fluidic pathways within its structure, allowing fluid to pass through without requiring external routing, thus simplifying the overall system architecture.
2Reliability
If gripper blocks are assembled with external supply lines, then fluid distribution is achieved, but assembly becomes time-consuming and costs increase
Solution Approach 1:
The patent combines the fluid distribution function with the coupling function in a single intermediate piece. This integration allows gripper blocks to be assembled directly together with fluid pathways already established, eliminating the time-consuming task of routing and connecting external supply lines during assembly.
Solution Approach 2:
The fluidic channels are pre-formed within the intermediate piece during its manufacturing process. This preliminary action of pre-establishing fluid pathways means that when gripper blocks are assembled using the intermediate piece, fluid distribution is immediately functional without requiring additional assembly steps for supply line installation.
3Volume of moving object
If a compact design is implemented, then space efficiency is improved, but achieving leak-free fluid transmission becomes more difficult
Solution Approach 1:
By merging the fluidic channels directly into the intermediate piece structure, the patent achieves compact integration without compromising leak-free transmission. The channels are embedded within the intermediate piece's body, eliminating external connections that would create leakage points, thus maintaining both compactness and reliability.
Solution Approach 2:
The intermediate piece is designed to be self-contained with integrated fluidic channels that are sealed within its structure. This self-service design means the intermediate piece independently provides both coupling and fluid transmission functions without requiring external components, reducing leakage risks while maintaining compact dimensions.
