Innovation Solution
A system comprising a first array and a second array connected via an interlinking connection, with integrated circuits and contact patches, and optionally including a battery management system, to simplify the installation and reduce complexity by using flexible printed circuits and jumper wires that do not require additional fastening devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional connection methods with multiple fastening devices are used to connect battery arrays, then the connection stability is improved, but the device complexity and packaging difficulty increase
Solution Approach 1:
The patent combines multiple fastening functions into a single integrated connection structure. The connection structure includes conductive elements that simultaneously provide electrical connection and mechanical fastening, eliminating the need for separate fastening devices and reducing overall system complexity while maintaining connection stability.
Solution Approach 2:
The connection structure serves multiple functions simultaneously: it provides electrical conductivity between battery arrays, mechanical support through integrated fastening, and structural alignment. This multi-functionality reduces the number of separate components needed and simplifies the overall packaging arrangement.
2Reliability
If multiple separate connections are used to connect battery arrays, then the connection reliability is improved, but the organization and installation complexity increase
Solution Approach 1:
The patent merges multiple separate connection operations into a single integrated connection structure that establishes both electrical and mechanical connections simultaneously. This reduces the number of installation steps and simplifies the organization process while maintaining reliable connections through the integrated design.
3Stability of the object's composition
If additional fastening devices and mounts are used to secure battery arrays, then the structural stability is improved, but the packaging space and device complexity increase
Solution Approach 1:
The patent integrates fastening functions directly into the connection structure itself, eliminating the need for separate mounts and clips. The connection structure includes built-in fastening elements that provide structural stability while occupying minimal additional space, as the fastening capability is incorporated into the existing connection volume rather than adding separate components.
