Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional energy store modules are used in vehicles, then the vehicle can transport loads and supply electrical consumers, but the energy store modules are not easily interchangeable and do not optimize energy supply for different applications
Solution Approach 1:
The energy storage system is divided into separate, interchangeable energy store modules that can be independently exchanged. Each module is a self-contained unit with standardized interfaces, allowing different module types (battery, ultracapacitor) to be swapped without affecting the overall system architecture or requiring complex reconfiguration.
2Productivity
If energy store modules are made interchangeable with insert parts, then rapid exchange is possible, but the structural complexity of the housing component increases
Solution Approach 1:
The housing component incorporates an insert part that can dynamically change position between inserted and removed states. This dynamic element allows the housing to adapt its configuration based on whether an energy store module is present, enabling rapid exchange while maintaining structural integrity through a relatively simple mechanism.
3Power
If ultracapacitor modules are used for high peak current values, then rapid charging is possible, but the energy storage capacity is lower compared to battery modules
Solution Approach 1:
Different regions of the energy storage system use different module types optimized for specific functions. Ultracapacitor modules are deployed in locations where high peak current and rapid charging are required, while battery modules are positioned for sustained energy supply. The DC/DC converter strategically manages power flow to match each module type's optimal operating characteristics to the specific demands of different consumers.
4Adaptability or versatility
If a DC/DC converter is integrated with the energy store module, then adaptable energy supply is enabled, but the complexity of the energy store module increases
Solution Approach 1:
The DC/DC converter is integrated directly into the energy store module, merging the energy storage function with the voltage conversion and power management functions. This consolidation allows the module to autonomously adapt its output to match the requirements of different consumers, eliminating the need for separate power management components and reducing overall system complexity.

Implementation Method 1
an inductive supply via a secondary winding on the underside of the vehicle is possible, and all consumers of the vehicle are supplyable from the secondary winding as long as they are inductively coupled with sufficient strength to a primary conductor installed in the floor

AI summary
A vehicle, in particular a logistics vehicle, includes a frame and a housing component secured in place thereon. An insert part on the housing component is insertable into a space region of the vehicle, and a first or a second energy store module is situated on the insert part and a DC/DC converter which is electrically connected to the energy store module.
