Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If traditional concrete blocks are used, then cost is reduced, but thermal resistance deteriorates

Engineering Contradiction:
Improvethermal resistanceVSAvoidcost
Core Design Contradiction:
Loss of energyVSEase of manufacture

Solution Approach 1:

The building block combines plastic insulation material with concrete structural elements to create a composite structure. The plastic core provides thermal insulation while the concrete outer layer provides structural strength and durability, resolving the contradiction between thermal resistance and cost by integrating materials with complementary properties.

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

Different parts of the building block have different material properties: the inner core uses plastic for insulation, while the outer surface uses concrete for strength. This local differentiation allows each material to perform its optimal function, achieving good thermal resistance without the full cost penalty of using expensive insulation materials throughout.

Inventive Principle:
Principle #3Local quality

2Productivity

If concrete blocks with mortar joints are used, then structural strength is maintained, but assembly time increases due to drying requirements

Engineering Contradiction:
Improveassembly timeVSAvoidstructural integrity
Core Design Contradiction:
ProductivityVSStability of the object's composition

Solution Approach 1:

The building block is segmented into distinct functional zones: an insulating plastic core and a structural concrete shell. This segmentation allows the concrete to be poured directly onto the plastic without requiring mortar joints, eliminating drying time while maintaining structural integrity through the integrated design.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The plastic insulation and concrete structure are merged into a single monolithic building block. This integration eliminates the need for separate mortar layers and allows for direct assembly of blocks without drying time, significantly improving productivity while maintaining structural stability through the combined material system.

Inventive Principle:
Principle #5Merging (Combining)

3Loss of energy

If adhesive mortar is applied between concrete blocks, then blocks are bonded together, but thermal bridges are created reducing energy efficiency

Engineering Contradiction:
Improveenergy efficiencyVSAvoidblock bonding
Core Design Contradiction:
Loss of energyVSEase of manufacture

Solution Approach 1:

The harmful adhesive mortar layer is completely removed from the construction system. Instead of bonding blocks with mortar that creates thermal bridges, the plastic-insulated concrete blocks are designed to interlock directly, eliminating the thermal bridge effect and improving energy efficiency while still achieving block bonding through the plastic protrusions and recesses.

Inventive Principle:
Principle #2Taking out (Extraction)

4Loss of energy

If thicker building blocks are used to improve thermal resistance, then insulation performance increases, but footprint increases reducing useful surface area

Engineering Contradiction:
Improvethermal resistanceVSAvoidfootprint
Core Design Contradiction:
Loss of energyVSArea of stationary object

Solution Approach 1:

The thermal resistance is improved not by increasing the overall thickness of the building block (which would increase footprint), but by changing the material parameters - specifically using plastic insulation material with high thermal resistance properties. This allows achieving good insulation performance while maintaining a compact footprint suitable for urban planning constraints.

Inventive Principle:
Principle #35Parameter changes
