Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional steel pipe pile with spiral blade is used, then the structure is simple and easy to manufacture, but the ground biting capability is insufficient and installation is difficult
Solution Approach 1:
The tip member is divided into distinct functional segments: a conical body part for penetration, streak projection parts for excavation, and a circular base part for attachment. This segmentation allows each part to perform its specific function optimally while maintaining overall structural integrity and ground biting capability.
Solution Approach 2:
The invention transitions from a simple spiral blade on a cylindrical pipe to a three-dimensional conical structure with projection parts extending radially outward. This dimensional change creates multiple engagement points with the ground, significantly enhancing ground biting and excavation capabilities during rotation.
2Productivity
If a conventional rotary penetrating pile with tapered parts and blades is used, then excavation can occur, but the structure is complex and the excavation efficiency is reduced due to boulder stone interference
Solution Approach 1:
The invention extracts the complex tapered structure from conventional designs and replaces it with a simpler conical body part combined with streak projection parts. This extraction of unnecessary complexity while retaining the essential conical penetration function allows for more efficient excavation by reducing structural interference with boulder stones.
Solution Approach 2:
The conical body part utilizes a smooth curved surface that tapers uniformly from the base to the vertex. This curvature allows for continuous ground engagement during rotation, enabling the streak projection parts to effectively excavate material without the interference caused by angular or segmented structures.
3Force
If the streak projection part extends linearly along the generatrix of the cone, then the excavation force is optimized, but the manufacturing precision requirements increase
Solution Approach 1:
The streak projection parts are positioned at specific locations on the conical body part, extending linearly along the generatrix from the maximum diameter section toward the vertex. This local positioning optimizes excavation force at critical zones while the conical geometry provides inherent guidance for manufacturing alignment, reducing overall precision requirements.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The tip member facilitates easy and secure installation by providing superior excavation force and balanced ground penetration, ensuring the anchor is firmly fixed without being easily pulled out.
Implementation Method 1
a conical body part tapering from the circular base part toward the tip
Implementation Method 2
a streak projection part being provided integrally on an outer surface of the conical body part in a form projecting outward between a maximum diameter part of the conical shape and a vertex of the conical shape and in a form extending linearly along a generatrix of the cone
Implementation Method 3
a ground biting part formed substantially in a spiral shape for biting into the ground is provided on an outer circumferential surface of an elongated body with a circular cross section so that the fixing tool of ground installation anchor type can be installed by being rotated about an axis and thereby biting into the ground
