Engineering Contradiction Analysis
1Ease of operation
If conventional transport trolleys are used for aircraft wings, then they can transport the wing from storage to assembly location, but they are bulky and difficult to maneuver
Solution Approach 1:
The transport trolley is divided into separate functional modules: a base unit with displacement means, a separately movable deck, and a hexapod platform that can be independently positioned. This segmentation allows each component to be optimized for its specific function while reducing the overall footprint when not in use.
Solution Approach 2:
The deck is made translationally mobile on the base through motorized systems, allowing dynamic adjustment of the deck position relative to the base. The hexapod platform provides six degrees of freedom for dynamic positioning of the load. This dynamic capability enables the trolley to adapt its configuration to minimize footprint while maintaining maneuverability.
2Manufacturing precision
If a hexapod platform is used for fine positioning, then positioning precision is improved, but device complexity increases
Solution Approach 1:
The hexapod platform serves multiple functions: it supports the load, provides fine positioning in six degrees of freedom, and integrates with the motorized deck system for coordinated movement. This multi-functionality justifies the structural complexity by eliminating the need for separate positioning and support systems.
Solution Approach 2:
The manual positioning mechanisms are replaced with motorized systems controlled by a control unit. The hexapod's six actuators are controlled electronically rather than through complex mechanical linkages, reducing mechanical complexity while maintaining high positioning precision through electronic control.
3Adaptability or versatility
If a mobile deck is used for position adjustment, then adaptability is improved, but device complexity increases
Solution Approach 1:
The deck displacement function is merged with the hexapod positioning system through coordinated control. The motorized system that moves the deck on the base is integrated with the hexapod's actuation system, allowing unified control of both deck position and platform orientation through a single control unit.
Solution Approach 2:
The control unit automatically coordinates the movement of the deck and hexapod platform based on positioning requirements. The system self-regulates the complex multi-axis movements without requiring external coordination, reducing operational complexity while maintaining high adaptability.

AI summary
A transport trolley for transporting a load comprising a base mounted on motorized wheels, a deck mounted to be translationally mobile on the base in a direction of translation, a first motorized system displacing the deck, a hexapod platform comprising a platform and a set of six jacks in which each is mounted articulated between the deck and the platform. The platform comprises a plurality of bearing points configured to come under the load and each bearing point takes the form of a receptacle with its opening oriented upwards. A control unit controls each motorized wheel, the first motorized system and each jack. The use of a hexapod platform makes it possible to finely position the wing at its position of fixing onto the fuselage and the use of a mobile deck supporting the hexapod platform allows for adjustability of the position despite a smaller footprint around the aircraft.
