Innovation Solution
A structural wall design featuring cross-linked or exogenous elements that allow interior filling, utilizing renewable materials like wood and expanded polystyrene to distribute loads and provide insulation, enabling prefabrication and on-site filling with a variety of materials for thermal, acoustic, and fire resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If internal structural elements (pillars, diagonals, chains) are placed in the longitudinal axis of the wall, then structural strength and stability are improved, but the ability to fill the wall interior is blocked
Solution Approach 1:
The patent removes internal structural elements (diagonals, chains, pillars) from the longitudinal axis of the wall and relocates them to the external surface. This extraction allows the interior cavity to remain open and accessible for filling with insulating materials, while the external structural elements maintain the wall's strength and stability.
Solution Approach 2:
The patent transitions structural elements from a one-dimensional internal arrangement (along the longitudinal axis) to a two-dimensional external arrangement (on the surface plane). This dimensional change enables the interior space to be utilized for filling while external elements provide structural support.
2Temperature
If wall thickness is increased to improve insulation and stability, then thermal and acoustic insulation are improved, but material transport and construction complexity increase
Solution Approach 1:
The patent divides the wall into two functional parts: a thin structural shell (providing strength with minimal material) and an interior cavity (filled with insulating materials). This segmentation allows the wall to achieve high insulation performance without proportionally increasing the quantity of structural material required.
Solution Approach 2:
The patent creates a composite wall structure combining a thin structural shell (wood, metal, or other materials) with insulating fill materials (expanded polystyrene, glass wool, polyurethane foam). This composite approach achieves superior thermal and acoustic insulation while minimizing the quantity of each individual material used.
3Ease of manufacture
If conventional wall systems are used, then construction is simplified, but industrialization of filling placement is prevented
Solution Approach 1:
The patent employs pre-fabricated wall panels with integrated external structural elements and pre-installed insulation layers. These panels are manufactured off-site with precision and then assembled on-location, enabling industrialized production while simplifying on-site construction. The open interior cavity is prepared in advance to receive bulk filling materials efficiently.

AI summary
Structural wall with frame in wood, metal, plastic, polycarbonate or other resistant material that has no diagonals or chains strengtheners on its longitudinal axis or, in their absence, its structure is reticulated or articulated. This wall Gets the necessary rigidity through a structuring external to its longitudinal axis by different diagonal elements attached to studs or pillars and slabs, in way to allow a spill or padding to your interior with materials that you they give this wall performance of habitability, such as thermal insulation, acoustic insulation, thermal inertia and resistance the fire, using very cheap fillers as the soil of the place or simple mixtures as the with chaff mud, mud with expanded polystyrene, light concrete, soil with chip wood, soil and volcanic ash, or even the use of industrial waste as chopped tires or other items, some difficult to recycle; In short, you can use a wide range of fillers, depending on the specific need. This way of structuring allows, through the possibility of access at work inside a padded, improving ostensibly simple, fast and economic benefits of habitability of the walls, being easily prefabricate and industrialize, and with a great variety of applications in homes and various types of buildings.
