Solution Overview
Problem
Existing drill heads for creating boreholes in insufficiently load-bearing subsoil are inefficient in terms of production cost, storage, and transport, and require lengthy borehole creation times.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a drill head is constructed as a welded construction, then the structural strength and stability are improved, but the space required for transport and storage increases significantly
Solution Approach 1:
The drill head is divided into separate modular components: a base plate and multiple drill head plates that can be detached and stored separately. This segmentation allows each component to be compact during transport while maintaining structural integrity during operation, resolving the contradiction between strength and transport volume.
Solution Approach 2:
The drill head plates are designed to nest within or against each other when not in use, with smaller components fitting into spaces between larger ones. This nesting arrangement minimizes the overall volume occupied during storage and transport while preserving the complete structural assembly when deployed.
2Ease of manufacture
If the drill head uses a simple base plate design without additional plates, then the manufacturing cost and complexity are reduced, but the borehole creation time increases
Solution Approach 1:
The drilling function is segmented across multiple plates (base plate and drill head plates) that work in parallel. Each plate contributes to soil displacement and borehole formation simultaneously, increasing overall productivity while maintaining simple manufacturing of individual plate components.
Solution Approach 2:
The drill head plates are designed with curved or arcuate surfaces that efficiently engage and displace soil material during rotation. These curved geometries optimize the mechanical action for borehole creation, enhancing productivity without requiring complex manufacturing processes.
3Stability of the object's composition
If the drill head plates are aligned perpendicularly on the base plate, then the structural stability and soil displacement efficiency are improved, but the device complexity increases
Solution Approach 1:
Different regions of the drill head have specialized functions: the base plate provides structural support and mounting, while the perpendicular drill head plates provide soil engagement and displacement. This local specialization optimizes each component's performance while maintaining overall stability without excessive complexity.
Solution Approach 2:
Multiple functional elements (base plate, drill head plates, connection mechanisms) are merged into a single integrated assembly that operates as one cohesive unit. This merging simplifies the overall device structure while maintaining the stability benefits of perpendicular plate alignment.

AI summary
A drill head (1) for a drilling device for creating boreholes in insufficiently load-bearing soil by displacing the soil material has a base plate (2) to which the end of the drill pipe can be detachably connected and closed. At least one drill head plate (3), oriented substantially perpendicular to it, can be placed on this base plate (2). At least one arc-shaped plate can be inserted into the lateral flanks (9, 15) of the drill head plate (3). This arc-shaped plate is equipped with first retaining elements (10), which are held in second retaining elements (11) attached to the lateral flanks (9, 15) of the drill head plate (3). The arc-shaped plate (8) is designed and inserted into the flanks of the drill head plate (3) such that its surfaces act as screw surfaces during the drilling process. This improves the efficiency of the drilling.
