Multi-Orientation Battery Contact Planes for Vibration Resilience
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery systems for portable electronic devices experience instant power interruptions due to external forces or vibrations, leading to abnormal shutdowns and potential device damage, as the contact between the battery pack and the device is disrupted.
Innovation Solution
A battery with multi-orientation conductions featuring a casing with differently angled contact planes and electrical connecting assemblies that can maintain power transmission by switching to alternative contact points when one connection is interrupted, ensuring continuous power supply.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single contact pad and receiving element are used for power transmission, then the structure is simple, but power supply is interrupted when the battery pack displaces due to external forces or vibrations
Solution Approach 1:
The battery pack is divided into multiple contact planes (at least two) with different vertical directions, and the receiving element is segmented into multiple receiving points corresponding to different contact planes. This segmentation allows the system to maintain power supply through alternative contact points when the battery pack displaces, resolving the contradiction between reliability and complexity by distributing the power transmission function across multiple independent contact interfaces.
Solution Approach 2:
The invention introduces multi-dimensional contact planes with different vertical directions (e.g., first vertical direction and second vertical direction perpendicular to each other). This dimensional diversification allows the electrical connecting assemblies to maintain contact with different receiving points based on the displacement direction, thereby maintaining power supply reliability without requiring excessive complexity in a single plane.
2Adaptability or versatility
If the battery pack is allowed to move freely to accommodate external forces, then the device is more adaptable, but the contact between receiving element and contact pad is disrupted causing power interruption
Solution Approach 1:
The invention creates a dynamic contact system where the battery pack can displace in response to external forces while maintaining electrical connection. The multiple contact planes and receiving points are arranged such that as the battery pack moves, different contact plane-receiving point pairs engage, allowing the system to adapt to displacement while maintaining continuous power supply, thus resolving the contradiction between adaptability and reliability.

AI summary
A battery (100) includes a casing (110), a battery pack (120), and at least two electrical connecting assemblies (130). The casing (110) includes an inner space (111) and plural contact planes (140). Vertical directions of the contact planes (140) are different. The battery pack (120) includes a battery cell (121) disposed in the inner space (111), and the battery pack (120) includes a positive electrode (120a) and a negative electrode (120b). The electrical connecting assemblies (130) are electrically connected to the positive electrode (120a) and the negative electrode (120b) respectively, so as to transmit power between the battery pack (120) and an electronic device. The electrical connecting assembly (130) electrically connected to the positive electrode (120a) is arranged on at least two of the contact planes (140), and the electrical connecting assembly (130) electrically connected to the negative electrode (120b) is arranged on at least two of the contact planes (140). If power supply in one certain direction is interrupted, the battery (100) transmits power in the other directions, thereby avoiding power supply from being interrupted.
