Post and Beam Coupling with Pre-Cut Slot Connectors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing post and beam systems lack the capability to couple beams to posts in a safe, rapid, accurate, eye-appealing, and economical manner.
Innovation Solution
A post and beam system comprising a beam with a vertically disposed slot and beam holes, a post with a connector having beam apertures, and dowels extending through the beam holes and apertures to securely couple the beam to the post, allowing for efficient and accurate assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional post and beam coupling methods are used, then structural integrity can be maintained, but the assembly process is time-consuming and labor-intensive
Solution Approach 1:
The patent applies preliminary action by pre-cutting slots in the beams and pre-drilling holes in both beams and posts before assembly. The connector pieces are also prepared in advance with matching dimensions. This preliminary preparation eliminates the need for on-site cutting and drilling during assembly, significantly reducing assembly time and labor requirements while maintaining structural integrity through precise pre-fitted connections.
2Manufacturing precision
If traditional coupling methods are used, then safety can be ensured, but accuracy and precision in alignment are difficult to achieve
Solution Approach 1:
The patent introduces connector pieces as intermediary elements that mediate between beams and posts. These connectors feature slots that receive dowels and have predetermined geometries that ensure precise alignment. The intermediary connectors act as alignment guides, making it easy to achieve accurate positioning while maintaining reliable and safe couplings through the standardized connection mechanism.
3Ease of manufacture
If custom coupling solutions are developed, then aesthetic appeal can be improved, but material and manufacturing costs increase
Solution Approach 1:
The patent applies segmentation by dividing the coupling system into separate, modular components: beams with slots, posts with holes, and intermediate connector pieces. This segmentation allows each component to be manufactured independently using standard woodworking processes, reducing manufacturing costs. The modular design also enables flexible arrangement and configuration to achieve various aesthetic appearances while maintaining ease and economy of manufacture.

AI summary
A beam has an upper face, a lower face, side faces, and an end face. The end face has a rectangular configuration and is vertically disposed. The end face has a slot vertically disposed and parallel with, and equally spaced from, the side faces. Beam holes extend through the beam on opposite sides of the slot. A post has a front face, a parallel rear face, and parallel side faces. A connector has a first section and a second section. Beam apertures are formed in the first section. The first section is positioned in the slot with the beam apertures aligned with the beam holes. The second section is attached to the post. Dowels extend through the beam holes and the beam apertures thereby coupling the beam to the post. The system also includes tools for accurately cutting and drilling components, wood and otherwise, to be coupled.
