Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional machinery systems are used to manipulate modules in confined spaces, then the modules can be manipulated with sufficient accuracy, but the assembly and dismantling of multiple elements (upper beams, lower beams, support elements) is required, resulting in significant assembly times
Solution Approach 1:
The machinery system is divided into separate functional modules: a mobile platform for positioning, a cantilever arm for manipulation, and fixing devices for module attachment. This segmentation allows each component to be optimized independently and enables faster assembly by reducing the number of elements that need to be assembled together in the aircraft housing.
Solution Approach 2:
The arm and fixing devices are pre-assembled on the mobile platform before entering the aircraft housing. This preliminary assembly eliminates the need to assemble structural elements (upper beams, lower beams, support elements) inside the confined space, significantly reducing assembly time while maintaining manipulation accuracy.
2Manufacturing precision
If traditional machinery systems with multiple assembly steps are used, then manipulation accuracy can be achieved, but the ability to handle multiple modules simultaneously is limited
Solution Approach 1:
The cantilever arm is designed with universal fixing devices that can attach to different types of modules (upper modules, lower modules) using the same attachment mechanism. This multi-functionality allows the system to handle multiple module types simultaneously without requiring different manipulation systems for each module type, thereby increasing productivity while maintaining precision.
Solution Approach 2:
The mobile platform provides dynamic positioning capability, allowing the arm to be repositioned between modules during manipulation. This dynamic adjustment enables the system to handle multiple modules simultaneously by quickly moving between different work positions, increasing productivity without compromising manipulation accuracy.
3Stability of the object's composition
If the arm is mounted on a fixed base, then structural stability is improved, but the system cannot be easily repositioned or adapted to different locations
Solution Approach 1:
A mobile platform serves as an intermediary between the fixed environment and the cantilever arm. This platform provides the necessary structural stability to support the arm while simultaneously enabling easy repositioning to different locations. The platform acts as a mediator that combines the benefits of both fixed and mobile mounting, resolving the contradiction between stability and adaptability.

AI summary
The machinery system comprises an arm having an upper fixing device arranged to fix to the arm at least one upper module to be manipulated in an upper plane and a lower fixing device arranged to fix to the arm at least one lower module to be manipulated in a lower plane; a first securing device of the arm configured to control the positioning of the arm; the arm being mounted cantilever-fashion on the first securing device. The machinery system makes it possible to at least halve the manipulation time for two modules by virtue of the arm mounted cantilever-fashion, to which two modules can be fixed.
