Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If gravity penetration is used to insert the probe rod into the seabed, then the penetration process is simple, but the insertion depth is uncontrollable and the soil mass is greatly disturbed
Solution Approach 1:
The patent replaces the uncontrolled mechanical gravity penetration system with a controlled static penetration system using a penetration device that applies controlled force through a guide mechanism, enabling precise depth control while maintaining operational simplicity
Solution Approach 2:
The patent introduces a penetration device as an intermediary between the probe rod and the seabed, which mediates the penetration process by providing controlled force application and depth limitation, preventing direct uncontrolled impact with the seabed
2Ease of manufacture
If gravity penetration is used, then the penetration process is simple, but the penetration position cannot be controlled vertically
Solution Approach 1:
The patent replaces the uncontrolled gravity-based mechanical penetration with a guided static penetration system that uses a guide mechanism to ensure vertical alignment and precise positioning during insertion
Solution Approach 2:
The patent applies preliminary positioning actions through the guide mechanism and penetration device before the actual penetration occurs, ensuring the probe rod is correctly aligned and positioned vertically before force is applied
3Force
If hydraulic transmission device is used for static penetration, then the penetration force is provided, but the penetration efficiency is low due to fluid flow resistance and hydraulic oil leakage
Solution Approach 1:
The patent replaces the hydraulic transmission system with a direct mechanical penetration device that applies force through a guide mechanism, eliminating fluid flow resistance and hydraulic oil leakage while maintaining penetration force and improving efficiency
Solution Approach 2:
The patent extracts the hydraulic transmission components from the penetration system, removing the source of fluid flow resistance and leakage, and replaces them with a direct mechanical force application system
4Force
If hydraulic transmission device is used, then penetration force is provided, but the equipment is bulky and heavy causing great disturbance to soil mass
Solution Approach 1:
The patent extracts and removes the bulky hydraulic transmission equipment from the penetration system, replacing it with a compact mechanical penetration device that provides sufficient penetration force without the excessive size and weight of hydraulic systems
Solution Approach 2:
The patent substitutes the complex hydraulic mechanical system with a simplified direct mechanical penetration device that achieves the required penetration force through a more compact and lighter design
5Force
If hydraulic penetration equipment is used, then penetration force is provided, but the performance is easily affected by temperature changes
Solution Approach 1:
The patent replaces the hydraulic transmission system with a direct mechanical penetration device that does not rely on fluid-based hydraulic oil, eliminating the performance degradation caused by temperature changes on hydraulic fluid properties
