Modular Assembly Jig System for On-Site Construction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional construction methods are inefficient due to the need for off-site assembly and transportation of large, hollow prefabricated elements, leading to high transportation costs and laborer fatigue from bending and handling heavy objects in precarious positions.
Innovation Solution
A modular assembly jig system that can be configured on-site, comprising a jig platform assembly, support assembly, alignment assembly, guide assembly, adjustable clamp assembly, and extension assembly, allowing for secure and adjustable construction of structural elements directly on the site, reducing the need for off-site fabrication and minimizing laborer strain.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If prefabricated elements are assembled offsite and transported to construction site, then construction speed is improved, but transportation cost increases and space efficiency deteriorates
Solution Approach 1:
The system divides the construction process into modular components - a reusable jig platform and discrete structural elements (walls, roofs, floors) that can be assembled on-site. This segmentation eliminates the need to transport large hollow prefabricated assemblies, reducing transportation costs while maintaining construction speed through standardized modular components
Solution Approach 2:
The jig platform assembly serves as an intermediary device that enables efficient on-site assembly of structural elements. It provides a stable working platform with integrated guides and clamps, allowing rapid construction without transporting complete prefabricated structures, thus resolving the contradiction between construction speed and transportation efficiency
2Ease of operation
If structural assemblies are constructed on horizontal plane, then ease of operation is improved, but laborer fatigue increases and safety deteriorates
Solution Approach 1:
The jig platform elevates the construction workspace from ground level to an elevated platform, changing the vertical dimension of work. This allows structural elements to be assembled at ergonomic heights on the platform while maintaining horizontal assembly benefits, reducing back strain from bending and improving safety by providing stable working surfaces with integrated fall protection
3Adaptability or versatility
If modular assembly jig system is configured on-site, then adaptability is improved, but device complexity increases
Solution Approach 1:
The jig system is segmented into standardized modular components (platform members, support members, interconnects) that can be configured for different structural assemblies. This segmentation provides adaptability for various construction needs while keeping individual components simple and manageable, reducing overall system complexity through standardization
Solution Approach 2:
The jig platform components are designed as universal, multi-functional elements that can be reused across different construction projects and configurations. The standardized interconnects and modular design allow the same basic components to serve multiple purposes, reducing device complexity while maintaining high adaptability to different structural requirements

AI summary
A modular assembly jig system for use in constructing a structural element on a construction site is disposable between an operative assembled configuration and a collapsed configuration for transport or storage. The system includes a jig platform assembly comprising a plurality of platform members, and a support assembly disposed in a supporting relation to the jig platform assembly. An alignment assembly disposed along the jig platform assembly facilitates alignment of a portion of the structural element during construction. A guide assembly having at least one guide member is at least temporarily interconnected to the jig platform assembly, and an adjustable clamp assembly is operatively positionable along at least a portion of the guide assembly. The adjustable clamp assembly retains at least a portion of the structural element in position during construction. An extension assembly is provided to increase an operative working area of the jig platform assembly.
