Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If traditional masonry materials (bricks, concrete blocks) are used, then structural strength and durability are achieved, but environmental impact and carbon footprint increase

Engineering Contradiction:
Improvestructural strengthVSAvoidenvironmental impact
Core Design Contradiction:
StrengthVSObject-affected harmful factors

Solution Approach 1:

The patent changes the material parameter from traditional masonry materials to bio-based panels containing natural fibers (wood, cotton, hemp, bamboo, grass). This parameter change maintains structural integrity while eliminating the environmental harm associated with conventional materials, as the bio-based materials are renewable and biodegradable

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The invention uses composite materials consisting of natural fibers bonded with a binding agent to form panels. This composite approach creates materials that are both structurally sound and environmentally friendly, combining the strength of natural fibers with the bonding properties of adhesives to achieve durability without environmental harm

Inventive Principle:
Principle #40Composite materials

2Productivity

If building blocks are designed for easy assembly and disassembly, then installation speed and flexibility improve, but structural stability and connection strength may deteriorate

Engineering Contradiction:
Improveinstallation speedVSAvoidstructural stability
Core Design Contradiction:
ProductivityVSStability of the object's composition

Solution Approach 1:

The building system is segmented into modular panels with standardized connection elements. Each panel can be independently assembled and disassembled using the connection mechanism, enabling fast installation while maintaining structural stability through the standardized interlocking design that ensures proper alignment and secure bonding

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a connection element as an intermediary component between panels. This intermediary mechanism facilitates easy assembly and disassembly while ensuring structural stability through proper engagement of connection elements with the panels, acting as a mediator that balances accessibility with structural integrity

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If building blocks are made from renewable materials, then environmental sustainability improves, but manufacturing precision and material consistency may worsen

Engineering Contradiction:
ImproverenewabilityVSAvoidmaterial consistency
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The patent changes the material source from conventional to renewable bio-based materials while controlling manufacturing parameters to ensure consistency. By standardizing the composition ratios of natural fibers and binding agents, and controlling moisture content and density parameters, the invention achieves both renewability and manufacturing precision

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The invention applies local quality control by ensuring consistent distribution of natural fibers and binding agents within each panel. This localized quality assurance maintains material consistency across different panels while preserving the renewable nature of the materials through controlled processing of natural fiber sources

Inventive Principle:
Principle #3Local quality

AI summary

The invention describes a multi-layer building block (1) comprising at least two wooden layers (2), where the building block further comprises a first outer surface (3) and a second outer surface (5) and first to fourth inner surfaces (6, 7, 9, 10), where the first inner surface ( 6) comprises at least one primary locking groove (8a), and second inner surface (7) on the opposite side of the building block (1) comprises at least one primary locking groove (8a) at the same distance(s) from at least one of the outer surfaces (3, 5) as the at least one primary locking groove (8a) of the first the inner surface (6). All wooden layers (2) are glued together or indirectly attached to each other via a functional layer (15) and where each wooden layer includes one or more pieces of wood of approximately the same total thickness over, essentially, the entire area of the wooden layer. Furthermore, the invention includes a building block system which includes a primary locking strip (11a) which can lock the building blocks to each other and a method for building a wall with the building blocks.
