Electronic Load Switch Direct Contact for Energy Storage Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical circuits that connect energy storage devices or loads often require manual assembly of mechanically pressed spring contacts, which are costly and labor-intensive, and also necessitate additional temperature sensors for monitoring.
Innovation Solution
The use of an electronic load switch as an electrical contact on the circuit to directly connect energy storage devices or loads, eliminating the need for spring contacts and allowing the load switch to serve both as a mechanical and electrical interface, and potentially replacing mechanical switches, while also providing temperature monitoring capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If spring contacts are used for electrical connection of energy storage devices, then reliable electrical contact is achieved, but assembly effort and manufacturing complexity increase
Solution Approach 1:
The patent combines the electrical contact function and mechanical retention function into a single integrated load switch component. The load switch simultaneously provides electrical connection and mechanical retention of the energy storage device, eliminating the need for separate spring contacts and reducing assembly complexity while maintaining reliable electrical contact.
Solution Approach 2:
The load switch serves multiple functions: it acts as an electrical switch, an electrical contact, and a mechanical retention element. This multi-functionality reduces the number of components needed and simplifies the overall assembly process while ensuring reliable electrical connection.
2Reliability
If spring contacts and cables are used for contacting energy storage devices, then electrical connection is established, but manufacturing costs increase
Solution Approach 1:
The patent merges the electrical contact function with the load switch component, eliminating the need for separate spring contacts and cables. This integration reduces the number of parts that need to be manufactured and assembled, thereby lowering manufacturing costs while maintaining reliable electrical connection.
Solution Approach 2:
The patent extracts and eliminates unnecessary components (spring contacts and cables) from the system by using the load switch to directly contact the energy storage device. This reduction in component count directly reduces manufacturing costs.
3Measurement precision
If additional temperature sensors are installed for monitoring energy storage temperature, then temperature monitoring capability is achieved, but device complexity and assembly effort increase
Solution Approach 1:
The load switch is designed to serve dual purposes: electrical switching and temperature monitoring. By integrating a temperature sensor with the load switch, the system achieves temperature monitoring capability without adding separate sensor components, thereby reducing assembly effort and device complexity.
Solution Approach 2:
The patent combines the temperature monitoring function with the load switch component. The temperature sensor is integrated into the load switch housing or structure, allowing simultaneous electrical switching and temperature measurement without requiring additional separate mounting and wiring operations.
4Ease of operation
If mechanical switches are used for switching energy storage devices, then switching function is achieved, but the opportunity to integrate temperature monitoring and reduce component count is lost
Solution Approach 1:
The patent replaces the conventional mechanical switch with an electronic load switch that incorporates temperature monitoring capability. This electronic switch maintains the switching function while adding temperature monitoring, thereby increasing adaptability and versatility without compromising ease of operation.
