Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If air and/or additive is introduced to deeper soil layers using existing injection devices, then the substances can reach deeper layers, but the substances flow back to the surface along the device and cannot be spread to a large area
Solution Approach 1:
The patent inverts the traditional injection approach by using a tapered tip design that is wider at the bottom than at the top. This inverted geometry prevents backflow by creating a mechanical barrier at the soil interface, allowing the device to inject air and/or additive to deep layers while preventing substance loss through surface backflow along the device
2Productivity
If existing injection devices are used to introduce air and/or additive, then injection can be performed, but the devices cannot withstand long-term loads without deformation
Solution Approach 1:
The patent applies preliminary action by pre-compacting the soil around the injection device using a compaction element before injection. This pre-compaction creates a stable, load-bearing soil structure that supports the device during long-term operation, preventing deformation while maintaining injection capability
Solution Approach 2:
The device combines different structural elements (tapered tip, compaction element, injection channels) with distinct functions into a composite structure. This composite design allows each element to optimize its specific function while collectively providing both injection capability and long-term load resistance
3Ease of operation
If uniform injection is applied to all soil areas, then injection process is simple, but the proper quantity of air and/or additive cannot be adjusted according to different soil qualities
Solution Approach 1:
The patent implements dynamics by making the injection parameters adjustable based on real-time soil quality assessment. The device can modify injection pressure, flow rate, and duration dynamically according to soil conditions, enabling proper quantity adjustment while maintaining operational simplicity through automated control
