Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional compressed stabilized earth blocks are used without soil analysis and additives, then the construction process is simple and fast, but the stability, load carrying capability and lifespan of the wall are insufficient
Solution Approach 1:
The system performs preliminary analysis of soil properties before construction and pre-determines the required additives and their quantities. This advance preparation ensures optimal wall stability and lifespan while streamlining the actual construction process.
Solution Approach 2:
The system incorporates feedback mechanisms where soil analysis results directly inform additive selection and dosing. The automated system adjusts additive quantities based on measured soil properties, creating a closed-loop control system that optimizes wall performance.
2Reliability
If imported wood is used for sheet pilings, then the construction is quick and reliable, but the ecological footprint is large and costs are high due to frequent replacements
Solution Approach 1:
The invention changes the material parameters from imported wood to locally sourced stabilized soil. By modifying soil properties through additives and achieving optimal compression, the system creates durable sheet pilings with extended lifespan exceeding 100 years, eliminating the need for frequent replacements and reducing ecological impact.
Solution Approach 2:
The system utilizes locally available soil resources instead of imported materials. The soil stabilization process transforms ordinary local soil into a reliable construction material, making the system self-sufficient and eliminating dependence on external material sources.
3Object-affected harmful factors
If any type of local soil is used without additives, then the ecological footprint is reduced and local materials are utilized, but the wall lacks sufficient stability and load carrying capability
Solution Approach 1:
The system applies the principle of local quality by analyzing specific soil properties at each location and adding targeted additives to achieve the required strength characteristics. This localized approach allows any soil type to be optimized for wall construction while maintaining ecological benefits of using local materials.
Solution Approach 2:
The invention creates composite materials by combining local soil with stabilizing additives such as cement, lime, or fly ash. This composite approach enhances the mechanical properties of the soil while maintaining the ecological advantage of using locally sourced primary material.
4Strength
If high compression pressure is applied to achieve stable wall blocks, then the load carrying capability increases, but the energy consumption and construction time increase
Solution Approach 1:
The system performs preliminary soil stabilization by adding additives that improve soil cohesion and compressibility before the compression process. This pre-treatment reduces the energy required during compression while achieving the same or better strength outcomes.
Solution Approach 2:
The invention changes the physical and chemical parameters of the soil through additive incorporation, transforming it into a more compressible and cohesive material. This parameter modification enables effective wall block formation at lower compression pressures, reducing energy consumption.

AI summary
The invention relates toa method for creating a stabilized soil wall (1), comprising the steps of: supplying soil to the location where a wall element that is to become part of the wall is to be created, creating a compression space (2) at the location where the wall element is to be created, arranging an amount of soil in the compression space, compressing the soil in the compression space to obtain the wall element (6, 7), arranging the wall element at the location where the wall is to be created and, if required, compressing subsequent wall elements (6, 8) and arranging them adjacent to the first wall element until the desired wall size is achieved.
