Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing engineered wood structural systems face challenges in transmitting loads, particularly bending and twisting loads, due to non-rigid connections and interruptions in vertical continuity, which affects the structural integrity and efficiency of multi-story buildings.
Innovation Solution
The proposed engineered wood structural system uses a combination of vertical and horizontal structural elements made from high-strength engineered wood components connected through durable adhesives and reinforced spacers, with specific seat configurations and connectors to ensure continuous load transmission across multiple floor levels, including vertical, shear, and bending loads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If non-rigid connections are used between horizontal structural elements and wall panels, then vertical loads can be transmitted, but shear loads, bending loads, and twisting loads cannot be properly transmitted across the different constructive elements
Solution Approach 1:
The patent merges multiple connection functions into a single rigid connection system. The connection element simultaneously transmits vertical loads, shear loads, bending loads, and twisting loads between horizontal structural elements and wall panels, replacing the need for separate connection mechanisms for each load type.
Solution Approach 2:
The connection system employs composite construction combining horizontal boards, vertical spacers, and connection elements made of engineered wood or metal, creating a rigid joint capable of withstanding multi-directional loads while maintaining structural integrity.
2Ease of manufacture
If beams are stacked on top of wall panels to transmit vertical loads, then connections are simplified, but the vertical continuity of wall panels is interrupted, preventing continuous load transmission through multiple floor levels
Solution Approach 1:
The patent introduces vertical spacers as intermediary elements that extend through the height of horizontal structural elements. These spacers maintain the separation and continuity of wall panels across multiple floor levels, allowing load transmission without interrupting panel continuity.
Solution Approach 2:
The solution transitions from horizontal stacking of beams on panels to a three-dimensional interlocking system where vertical spacers penetrate through horizontal elements, creating continuous vertical pathways for load transmission while maintaining panel integrity.
3Ease of operation
If vertical connectors of beams in one direction interfere with vertical connectors of beams in another direction at the same structural node, then alignment is simplified, but the resistance and load transmission capability are reduced
Solution Approach 1:
The patent employs a hierarchical nesting arrangement where vertical spacers are positioned within the structural depth of horizontal beams, and connection elements are nested within the joint region. This allows multiple beams to converge at the same node without their connectors interfering, as each connector operates in its own nested spatial zone.

AI summary
An engineered wood structural system including multiple vertical structural elements (10) and multiple horizontal structural elements (20, 120) wherein multiple horizontal structural elements (20, 120) of the same floor level are laterally adjacent slabs connected to each other through a perimetral region of the upper horizontal board of one slab attached to a perimetral region of the upper horizontal board of other laterally adjacent slab directly, through complementary staggered steps or through a joint connector, to transfer horizontal loads.
