Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If electrical members are arranged in conventional configurations, then the power distribution apparatus can be assembled, but the space utilization is low and the mounting space required is large
Solution Approach 1:
The patent transforms the conventional three-dimensional arrangement of electrical members into a two-dimensional planar layout by designing the electrical assembly to be flat in the thickness direction. This dimensional reduction allows the electrical members to be arranged on the same plane or on multiple planes that are closely stacked, significantly improving space utilization and reducing the overall volume required for mounting the power distribution apparatus.
Solution Approach 2:
The patent integrates multiple electrical members (such as relays, fuses, and circuit breakers) into a single compact electrical assembly structure. By merging these previously separate components into one unified assembly with a standardized interface, the patent reduces the total mounting space required and simplifies the overall arrangement complexity while maintaining all necessary functional capabilities.
2Device complexity
If the power distribution apparatus occupies large space, then all electrical members can be accommodated, but the structural compactness of power consuming devices and batteries is affected
Solution Approach 1:
The electrical assembly is designed to be flat in the thickness direction (first direction), effectively reducing it to two dimensions. This allows the power distribution apparatus to occupy minimal space in the thickness direction while accommodating all necessary electrical members through careful planar arrangement, thereby improving structural compactness without compromising functionality.
Solution Approach 2:
The patent optimizes the dimensional parameters of the electrical assembly by controlling the ratio M (where 1≤M≤1.2) between the size of the electrical assembly in the first direction and the size of the largest electrical member in that direction. This parameter optimization ensures the assembly remains compact while accommodating all electrical members, directly improving structural compactness.
3Volume of moving object
If conventional electrical member arrangement is used, then assembly is straightforward, but space utilization is low and mounting space is large
Solution Approach 1:
Multiple electrical members are integrated into a single modular electrical assembly with a unified structure and standardized interface. This merging approach improves space utilization by compacting the arrangement of electrical members while maintaining ease of manufacture through modular design that allows the entire assembly to be installed as one unit, simplifying the manufacturing process.
Solution Approach 2:
The electrical assembly is designed with a universal interface and standardized structure that can accommodate different types of electrical members (relays, fuses, circuit breakers) in a compact arrangement. This multi-functional design maintains ease of manufacture by using standardized components and assembly methods while achieving high space utilization through optimized internal layout.

AI summary
A power distribution apparatus, a battery, and a power-consuming device are provided. The power distribution apparatus includes an electrical assembly comprising at least two electrical members. Among them, the electrical member with the largest size in a first direction is defined as the first electrical member. The size of the first electrical member in the first direction is not greater than its sizes in other directions. The ratio of the size of the electrical assembly to the size of the first electrical member in the first direction is defined as M, where 1≤M≤1.2. This configuration enables the apparatus to have a flatter structure, reduces the space it occupies in a preset direction, facilitates the layout of other components, enhances structural compactness, improves system performance, and helps lower manufacturing costs.
