Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different high-voltage distributors are used for different vehicle variants, then the specific requirements of each vehicle variant are met, but the costs increase and the number of variants becomes large
Solution Approach 1:
The patent implements a universal high-voltage distributor design where a single basic structure can serve multiple vehicle variants through configurable protection elements. The distributor includes multiple mounting devices that can accommodate different types and numbers of high-voltage protection elements (fuses, semiconductor protection elements) depending on the specific vehicle variant requirements, eliminating the need for completely different distributor designs for each variant.
Solution Approach 2:
The distributor is segmented into modular components with multiple independent mounting devices, each capable of being equipped with or without protection elements. This segmentation allows flexible configuration where only the necessary protection elements are installed for each vehicle variant, while the basic distributor structure remains the same across all variants.
2Adaptability or versatility
If existing high-voltage distributors are adapted for different vehicle variants, then the specific requirements are met, but the adaptation process is time-consuming
Solution Approach 1:
The distributor is pre-configured with multiple mounting devices that are ready to accommodate different protection elements. The grid dimensions are pre-designed to accept standard design classes of high-voltage protection elements, allowing quick assembly without time-consuming adaptations. The basic structure is prepared in advance with all necessary mounting positions available.
Solution Approach 2:
The distributor design allows dynamic configuration where protection elements can be easily added or removed from mounting devices based on specific vehicle variant requirements. The grid-based mounting system enables flexible reconfiguration without requiring structural modifications, reducing adaptation time significantly.
3Reliability
If the high-voltage distributor is equipped with protection elements, then safety is improved, but the device complexity increases
Solution Approach 1:
High-voltage protection is implemented locally at each mounting device through individual protection elements rather than a complex centralized protection system. Each mounting device can be independently equipped with appropriate protection elements (fuses, semiconductor protection elements) based on the specific requirements of the connected high-voltage outlet, simplifying the overall configuration.
Solution Approach 2:
The mounting devices are designed with self-contained protection capabilities where each device can independently provide high-voltage protection for its associated outlet. The grid dimension standardization allows mounting devices to self-configure with appropriate protection elements from standard design classes, reducing the complexity of system-wide protection configuration.

AI summary
The invention relates to a high-voltage distribution board for a hybrid or electric vehicle, in particular for a commercial vehicle, which can be easily and quickly adapted to the requirements of different vehicle variants without having to significantly alter the basic design of the high-voltage distribution board. The high-voltage distribution board comprises a support structure (23); a conductor arrangement (24a, 24b, 30a, 30b) arranged on the support structure (23) for current and voltage distribution to form several high-voltage outputs; several mounting devices (34) arranged on the support structure (23), each of which is assigned to a high-voltage output and can be equipped with a high-voltage fuse element (22), wherein, in the case of an unequipped mounting device, the assigned high-voltage output cannot be energized.
