Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing construction sets are limited in forming various types of corner joints at angles other than 90°, as they either restrict angle variation or require specific bevel end faces, lacking versatility in connecting structural elements at different orientations.
Innovation Solution
A model construction set with blocks of square cross-sections and rectangular faces of different widths, featuring inner longitudinal passages and round, identically sized holes for alignment, along with auxiliary parts like hollow cubes and block fragments for flexible connections, allowing for a wide range of corner joints from 0° to 180° regardless of block orientation, secured by standard fasteners.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional construction sets use blocks with limited connection methods, then assembly is simple, but the ability to form various types of corner joints at angles other than 90° is restricted
Solution Approach 1:
The construction set employs universal connecting elements that can form various types of corner joints at different angles (0° to 180°) regardless of block orientation. The connecting elements are designed with multiple functional capabilities, allowing them to adapt to different connection requirements without requiring specialized blocks for each angle type.
Solution Approach 2:
The system separates the connection functionality from the block structure by introducing independent connecting elements. These elements act as intermediaries that provide the angular adjustment capability, while the blocks themselves maintain simple cubic or rectangular shapes with standard holes, dividing the complexity into manageable components.
2Adaptability or versatility
If construction sets require specific bevel end faces to form various corner joints, then angle variation is possible, but ease of operation and alignment becomes difficult
Solution Approach 1:
The connecting elements serve as intermediaries between blocks, providing the angular adjustment capability without requiring modified block end faces. These intermediaries absorb the complexity of angle variation, allowing blocks to maintain simple geometries with standard hole patterns that are easy to align and assemble.
3Stability of the object's composition
If construction sets use fixed connection methods, then structural stability is achieved, but flexibility for movable connections is lost
Solution Approach 1:
The connecting elements are designed to provide both fixed and movable connection capabilities. The system allows structures to be assembled with stable fixed joints where rigidity is required, while also enabling movable connections that permit rotation or adjustment, thereby providing dynamic adaptability to different structural requirements.

AI summary
The invention relates to a construction set for erecting structures that can be assembled and disassembled. The technical result consists in expanding the functional capabilities of a construction set, which makes it possible to assemble a high-strength structure. The present model construction set comprises blocks with a square cross-section having faces of different widths and lengths, identical circular apertures, and an internal longitudinal passage, for connection in a longitudinal and a transverse direction to form angles that are rigidly and movably connected. The blocks are made of square tubing of compatible standard sizes. Provided are auxiliary parts produced by cutting away an end face of a block, making it possible to use the blocks as pivotable levers and to use a unified fastening connective element as a pivot pin, wherein the position of one of the blocks changes along spherical coordinates at any point of the surface of a hemisphere. The blocks are inserted into one another in order to increase the strength of structures.
