Foundation Truss Assembly with Automated Rail Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manual and semi-automatic processes in manufacturing box spring or foundation frame components are labor-intensive and limit production speeds, increasing labor costs and requiring substantial manual interaction for alignment and fastening operations.
Innovation Solution
A system and method for substantially automated formation of trusses for foundation frames, utilizing a first and second truss rail assembly station linked by a conveyor, with adjustable assembly conveyors, pusher rails, and actuated pusher blocks to align and secure wooden components, followed by automatic fastening using staplers or nail guns, enabling efficient transfer and assembly of trusses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual processes are used to align and assemble foundation components, then ease of operation is maintained, but productivity is limited and labor costs increase
Solution Approach 1:
The assembly process is divided into discrete stations (first truss rail assembly station, second truss rail assembly station) with specialized functions at each station, allowing simultaneous operations and improved throughput while reducing the skill level required at each individual station
Solution Approach 2:
Jigs and fixtures are introduced as intermediary devices that automatically position and align truss rails, blocks, and slats during assembly, eliminating the need for manual alignment while ensuring precise positioning and repeatable quality
2Ease of operation
If semiautomatic equipment is introduced to reduce manual labor, then ease of operation improves, but device complexity increases and substantial manual interaction is still required
Solution Approach 1:
The assembly system uses standardized, multi-functional components and fixtures that can accommodate different truss configurations and sizes, reducing overall system complexity while maintaining versatility. The same basic fixture design can be adjusted for various production needs without requiring completely different equipment
Solution Approach 2:
The system incorporates self-aligning features and automatic feeding mechanisms that reduce the need for operator intervention. Components are designed to automatically position themselves during assembly, and the equipment performs its own basic functions without requiring constant manual oversight or adjustment

AI summary
A system and method for forming a foundation truss for a box spring or mattress foundation frame includes a first truss rail assembly station having a series of block feeders, a top rail hopper and a filler strip hopper that received stacks of truss components such as blocks, top rails and filler strips and feed such truss components into stacked registration. The stacked truss components are moved into engagement with a series of staplers that secure the filler strips, top rails and blocks together to form first truss rail portions, which are then fed to a second truss rail assembly station where a bottom rail is automatically applied thereto.
