Solution Overview

Problem

Existing methods for connecting wooden panels fail to create a monolithic structure that ensures stability, rigidity, and ease of assembly, while also allowing for efficient calculation of structural statics without needing individual panel-by-panel calculations.

Innovation Solution

A method involving the creation of cavities in adjacent panels' edges, insertion of a connecting element with inclined screw seats, and securing with screws at a 30°-70° angle, followed by sealing with adhesive tape to form a monolithic structure.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If wooden panels are connected using existing connecting elements (recessed connections), then assembly is simplified, but a monolithic structure cannot be ensured and stability is reduced

Engineering Contradiction:
Improveease of assemblyVSAvoidmonolithic structure stability
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The connecting element is divided into multiple functional parts: a first connecting part inserted into a recess in one panel, a second connecting part inserted into a recess in the other panel, and a connecting body joining these parts. This segmentation allows each part to perform specific functions (insertion, connection, stabilization) while collectively achieving both easy assembly and monolithic structure formation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The first and second connecting parts are nested within recesses of the wooden panels, with the connecting body extending between them. This nesting approach allows the connecting element to be embedded within the panel structure, creating a compact and stable connection that maintains the monolithic character while enabling straightforward assembly.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Ease of operation

If panels are connected without form coupling, then assembly is easier, but a stable monolithic structure cannot be ensured

Engineering Contradiction:
Improveease of assemblyVSAvoidstructural reliability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The connecting element is designed with pre-formed first and second connecting parts that are inserted into recesses before the panels are fully positioned. This preliminary insertion action enables form coupling to be established during assembly, ensuring both ease of operation and structural reliability without requiring complex post-assembly adjustments.

Inventive Principle:
Principle #10Preliminary action

3Manufacturing precision

If individual panel connections are calculated separately, then connection precision is improved, but design time and costs increase

Engineering Contradiction:
Improveconnection precisionVSAvoiddesign time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The connecting element merges multiple connection functions into a single standardized component that can be used across all panel joints. This standardization allows the entire wall structure to be calculated and designed as an integrated system rather than individual connections, reducing design time and costs while maintaining connection precision through the standardized geometry of the connecting element.

Inventive Principle:
Principle #5Merging (Combining)
