Truss Assembly Table With Bidirectional Ejection and Gantry Sensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing truss assembly tables are limited in their ability to eject built trusses from both ends and lack automatic control systems for securing connector plates to truss members during assembly.
Innovation Solution
The truss assembly table incorporates truss ejection assemblies that can be retracted or extended to eject trusses from the ends, truss end stop assemblies that engage and disengage truss members during assembly, and a control system with a gantry and sensor assembly to manage the assembly process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If truss ejection assemblies are added to enable ejection from both ends, then productivity is improved, but device complexity increases
Solution Approach 1:
The ejection system is divided into multiple independent ejection assemblies distributed along the table, with each assembly capable of independent operation. This segmentation allows the system to achieve bidirectional ejection capability while maintaining modular complexity, where each segment handles a specific ejection task without requiring complete system redesign.
Solution Approach 2:
The ejection assemblies are designed with universal functionality to operate in multiple positions and directions. Each assembly can function for both end ejection and side ejection operations, reducing the need for separate specialized mechanisms and thereby managing device complexity while improving productivity.
2Manufacturing precision
If automatic control system with sensor assembly is implemented, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
Sensor assemblies are integrated into the gantry and control system to provide real-time feedback on connector plate positioning and securing status. This feedback mechanism enables automatic adjustment and precise control of the connector plate application process, achieving high manufacturing precision while the modular feedback loops keep control complexity manageable.
Solution Approach 2:
The control system incorporates self-adjusting capabilities where the sensor assembly automatically detects positioning errors and the system self-corrects without external intervention. This self-service feature reduces the need for complex manual control mechanisms and achieves high precision through automated error correction.
3Ease of operation
If truss end stop assembly is made movable between engagement and non-engagement positions, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The end stop assembly is designed with dynamic positioning capability, allowing it to move between engagement and non-engagement positions as needed during different stages of truss assembly. This dynamic adjustment enables operators to easily control truss member engagement while the movement mechanism is kept simple through guided linear motion and minimal actuation points.
