Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The invention optimizes the proportion of sheep wool fiber strands in the earth mixture to achieve desired mechanical properties. By carefully controlling the fiber content and distribution, the mixture achieves improved horizontal thrust resistance and stability without excessive complexity in material composition or processing.

Inventive Principle:
Principle #35Parameter changes

3Stability of the object's composition

If multiple strata are stacked and compacted to form constructive elements, then structural stability is improved, but manufacturing time and process complexity increase

Engineering Contradiction:
Improvestructural stabilityVSAvoidmanufacturing efficiency
Core Design Contradiction:
Stability of the object's compositionVSProductivity

Solution Approach 1:

The constructive element is formed by stacking and compacting multiple strata of the earth-sheep wool mixture. Each stratum is compacted separately to ensure density and stability, then stacked consecutively to build the complete element. This segmented approach allows for controlled manufacturing of each layer while maintaining overall structural integrity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The sheep wool fiber strands are pre-mixed with the earth material before stacking and compaction. This preliminary preparation ensures uniform distribution of fibers throughout each stratum, improving horizontal thrust resistance and preventing shrinkage during the compaction and stacking process, thereby streamlining the manufacturing workflow.

Inventive Principle:
