Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If all adsorption pads arranged in a grid pattern are used for adsorption, then the adsorption coverage is maximized, but the detachment reliability deteriorates due to shape variations of the target object

Engineering Contradiction:
Improveadsorption coverage areaVSAvoiddetachment reliability
Core Design Contradiction:
Area of stationary objectVSReliability

Solution Approach 1:

The adsorption device is divided into multiple independently controllable adsorption pads arranged in a grid pattern. Each pad can be individually activated or deactivated based on the shape and position of the target object, allowing selective adsorption that adapts to different geometries while maintaining overall coverage capability

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system dynamically selects and activates specific adsorption pads based on real-time detection of the target object's shape and position. This dynamic adaptation allows the adsorption configuration to optimize both coverage area and detachment reliability for each specific target geometry

Inventive Principle:
Principle #15Dynamics

2Device complexity

If a fixed grid pattern of adsorption pads is used, then the device structure is simplified, but the adaptability to different target object shapes deteriorates

Engineering Contradiction:
