Relay Cavity Integration for Compact Power Distribution Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power distribution apparatuses have large design margins and space waste, leading to increased size and weight, which hinders miniaturization and increases production costs.
Innovation Solution
A power distribution apparatus with a base that includes an accommodating cavity and a relay fixedly mounted within, where the inner wall of the cavity connects to the relay, exposing part of the relay's outer wall, allowing the relay to be protected and omitting its own shell structure, thereby facilitating compactness and reducing design margin and space waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the relay is provided with its own shell structure for protection, then the relay is protected, but the overall size and weight of the power distribution apparatus increases
Solution Approach 1:
The patent merges the protective shell function from the relay into the base structure. The base's accommodating cavity serves dual purposes: it holds the relay and provides protection, eliminating the need for a separate relay shell. This integration reduces overall component count and weight while maintaining protection functionality.
Solution Approach 2:
The base structure is designed to perform multiple functions simultaneously: it accommodates the relay, provides mechanical protection through its cavity walls, and serves as a mounting structure. This multi-functionality eliminates the need for dedicated protective shells on individual components.
2Reliability
If the relay is provided with its own shell structure, then the relay is protected, but the design margin and space waste increase
Solution Approach 1:
The protective enclosure function is merged into the base structure. The accommodating cavity of the base serves as the protective environment for the relay, eliminating redundant shell structures and reducing overall apparatus volume.
Solution Approach 2:
The patent extracts the protective shell requirement from the relay component itself and transfers this protective function to the base structure. This separation allows the relay to be mounted openly within the cavity without its own shell, reducing total volume.
3Stability of the object's composition
If the relay is fixedly mounted with the inner wall of the accommodating cavity connected to the relay, then the mounting stability is improved, but the assembling complexity increases
Solution Approach 1:
The base structure is segmented to include specific positioning features such as protrusions or recesses that engage with corresponding features on the relay. This segmentation creates natural alignment and fixing points that simplify the assembly process while ensuring stable mounting.

AI summary
A power distribution apparatus, a battery, and an electrical device are described. The power distribution apparatus includes a base and a relay. The base forms an accommodating cavity. The relay includes a switch unit, and at least part of an outer wall of the switch unit is exposed in the accommodating cavity. An inner wall of the accommodating cavity is connected to the relay to fix the relay to the accommodating cavity. The power distribution apparatus can fix the relay in the accommodating cavity. Furthermore, the relay fixed in the accommodating cavity can use the inner wall of the accommodating cavity to replace its own shell structure. Therefore, the own shell structure of the relay can be omitted, an integrated and miniaturized power distribution apparatus can be formed, and design margin and space waste can be reduced.
