Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing furniture and building structures require professional tools for assembly, limiting user customization and flexibility, and existing self-assembling solutions lack a simple and stable connecting method.
Innovation Solution
A column-beam connecting assembly with an arc channel and anchor slots on the connecting column, and half T-shaped jointing heads on the connecting beam, allowing for tool-free assembly and a stable frame structure, utilizing a mortise and tenon structure for additional stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If professional assisting tools are used for assembly, then assembly stability and precision are improved, but assembly complexity and user requirements increase
Solution Approach 1:
The connecting assembly enables users to complete the assembly process themselves without professional tools. The groove and column head structure allows direct manual insertion and positioning, while the mounting part with anchor slots provides self-locking capability through simple snapping motion, eliminating the need for external assisting tools
Solution Approach 2:
The connecting assembly is divided into distinct functional components: the groove for positioning, the column head for insertion, and the mounting part with anchor slots for secure attachment. This segmentation allows each component to perform its specific function independently, achieving reliable assembly through simple individual elements rather than complex integrated tools
2Adaptability or versatility
If custom furniture is manufactured according to customer requirements, then adaptability is improved, but manufacturing time increases
Solution Approach 1:
The furniture system is segmented into standardized connecting assemblies that can be pre-manufactured and stored. These modular components with standardized grooves and mounting parts can be quickly reconfigured to create custom furniture layouts, eliminating the need for time-consuming custom manufacturing while maintaining adaptability
Solution Approach 2:
The connecting assembly enables dynamic reconfiguration of furniture structures. Users can easily assemble, disassemble, and rearrange the standardized components to create different furniture configurations according to changing requirements, providing customization without the time cost of traditional manufacturing
3Ease of operation
If simple connecting methods are used for assembly furniture, then ease of assembly is improved, but structural stability deteriorates
Solution Approach 1:
The groove is designed with a curved cross-section that receives the column head. This curved geometry provides guiding and centering functions during insertion, ensuring precise positioning. The curvature also creates natural contact points that enhance structural stability while maintaining simple manual assembly operations
Solution Approach 2:
The mounting part features asymmetric anchor slots positioned at specific locations. This asymmetric arrangement creates a unique snapping fit with the column head, preventing accidental disassembly while maintaining simple assembly. The asymmetric design ensures proper orientation and stable connection without complex mechanisms

AI summary
The invention discloses a column-beam connecting assembly capable of being manually assembled, including connecting columns and connecting beams. The connecting column is formed with an arc channel along the axial direction. The arc channel opens to the surface of the column as a groove. A number of pairs of anchor slots are shaped on both sides of the groove, and the anchor slots of the same pair are at the same height. Mounting parts for snapping into the anchor slots are shaped on both sides of the connecting beam. Half T-shaped jointing heads are provided on the outer ends of said mounting pans for connecting to the arc channel, and said jointing heads are either in the shape of a column head matching the arc channel, or in the shape of a hook head. A frame structure assembled by the connecting parts is further disclosed.
