Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If multiple power sources are used for clamping, then the clamping force can be sufficient, but the mechanism complexity increases and force balance becomes unstable
Solution Approach 1:
The patent merges multiple clamping functions into a single power source system. A single motor drives a transmission mechanism that simultaneously actuates multiple swing shafts, combining what would traditionally require separate power sources into one integrated system, thereby reducing complexity while maintaining sufficient clamping force.
Solution Approach 2:
The single power source is designed to perform multiple functions: it provides clamping force, maintains force balance across multiple jaws, and enables synchronized movement. The transmission mechanism serves as a universal driver for all clamp component sets, eliminating the need for separate motors for each clamping function.
2Adaptability or versatility
If flexible structure is used for clamping, then contact flexibility is improved, but force balance becomes unstable and clamping accuracy decreases
Solution Approach 1:
The patent employs dynamic transmission mechanisms that allow the swing shafts to rotate through controlled arcs. This dynamic design enables the clamp components to adapt to the object's surface while maintaining precise force application. The arc-shaped movement paths ensure that force is applied uniformly and predictably, combining flexibility with accuracy.
Solution Approach 2:
The transmission mechanism uses variable transmission ratios and adjustable swing shaft rotation angles to optimize force distribution. By changing these parameters dynamically, the system can adapt to different object shapes and sizes while maintaining stable force balance and high clamping accuracy throughout the contact area.
3Device complexity
If single power source is used, then mechanism complexity is reduced, but force balance and synchronicity become difficult to maintain
Solution Approach 1:
The patent introduces a transmission mechanism as an intermediary between the single power source and the multiple clamp component sets. This intermediary system distributes power evenly across all swing shafts, ensuring stable force balance. The transmission mechanism acts as a mediator that translates single-power input into synchronized multi-point output, maintaining stability despite the reduced number of power sources.
4Ease of manufacture
If conventional gripper structure is used, then ease of manufacture is maintained, but center alignment and force uniformity are compromised
Solution Approach 1:
The patent segments the clamping function into multiple independent clamp component sets, each with its own swing shaft and arc arm. This segmentation allows each component to be manufactured separately using conventional methods, while the modular design ensures precise center alignment through standardized connection points and symmetric arrangement. The segmented structure maintains ease of manufacture while achieving high precision alignment.
