Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for assembling structures using modular components are often complex and require skilled labor, limiting their accessibility and versatility for creating a variety of objects, such as furniture and playhouses, especially for children.
Innovation Solution
A method involving interlocking structural members with slots and bases featuring grooves allows for the sequential assembly of stable structures by a single individual, using interchangeable components that can be easily stacked, expanded, and disassembled, utilizing thumb screws for added stability when necessary, and can be made from various materials like foam or wood.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If modular components are used for assembling structures, then versatility and ease of assembly are improved, but structural stability and rigidity deteriorate
Solution Approach 1:
The structure is divided into multiple modular components (bases, support members, structural members) that can be independently manufactured and assembled. Each component has standardized grooves and slots that enable flexible reconfiguration while maintaining stability through precise geometric interlocking.
Solution Approach 2:
Structural members are nested within bases through groove-and-slot interfaces, creating a hierarchical assembly where smaller components fit into larger ones. This nesting provides both versatility in configuration and stability through deep engagement of interlocking features.
2Stability of the object's composition
If complex assembly methods are used, then structural stability is improved, but ease of operation and accessibility deteriorate
Solution Approach 1:
The grooves and slots are designed to self-align and self-lock when components are assembled. The geometric features guide proper positioning automatically, eliminating the need for complex alignment procedures or specialized tools, thereby maintaining stability while simplifying assembly.
Solution Approach 2:
The groove-and-slot interface acts as an intermediary mechanism that translates simple insertion motions into stable structural connections. This intermediary feature enables unskilled individuals to achieve rigid assemblies through straightforward assembly actions.
3Strength
If precision cuts are made for grooves and slots, then structural rigidity is improved, but manufacturing complexity and cost increase
Solution Approach 1:
The groove and slot designs serve multiple functions: they provide structural rigidity through precise geometric interlocking, enable easy assembly through self-alignment, and simplify manufacturing by using standardized forms that can be replicated across all components. This universal design achieves rigidity without proportionally increasing manufacturing complexity.

AI summary
A method for assembly of structural systems comprising structural members with slots. Specific structural members are sequentially interconnected in rigid alignment. A first structural member is positioned with two upward facing slots. A second structural member having a downward slot and an upward slot is engaged with the first structural member by engaging the downward slot with one of the upward slots of the first structural member providing a stable structure. A third structural member having a downward slot and an upward slot is engaged with the second structural member by engaging the downward slot with the upward slot of the second structural member providing a stable structure. A fourth structural member having two downward slots is engaged with the third structural member and the first structural member by engaging the downward slots with the upward slots providing a finished structure.
