Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If each standby battery product is connected to one USB power supply for charging, then the charging function is reliable and universal, but the charging process becomes inconvenient and time-consuming due to repeated plugging and unplugging

Engineering Contradiction:

Improvecharging function reliabilityVSAvoidcharging convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent combines multiple standby battery products into a single charging system where multiple batteries can be charged simultaneously through one power supply connection. The first standby battery product serves as both a power consumer and a charging station for the second standby battery product, eliminating the need for separate power supply connections for each battery.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The first standby battery product acts as an intermediary charging device between the power supply and the second standby battery product. It receives power through its power input interface and transfers charging current to the second battery through their mutual contact, simplifying the charging operation.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If multiple standby battery products are charged simultaneously using external power supplies, then the charging efficiency is improved, but the device complexity and number of power supply connections increase

Engineering Contradiction:

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent combines the power input and power output functions within a single standby battery product. The first standby battery product has both a power input interface for receiving power and the capability to transmit power to the second standby battery product through their mutual contact, creating a self-sufficient charging system.

Inventive Principle:

AI summary

An electrical charging system includes a charging socket and a standby battery product. The charging socket has a socket casing, and a power input interface on the socket casing and electrically connected to a first conductive contact that extends above the socket casing. The standby battery product has a battery casing with a battery housed inside the battery casing, the battery casing further including a conductive pin and a second conductive contact, with the conductive pin and second conductive contact electrically connected to the battery. When the battery casing is placed on top of the socket casing, the conductive pin is aligned with, and contacts, the first conductive contact, creating a charging path that is defined by the power input interface (which receives external power), the first conductive contact of the socket casing, the conductive pin of the battery casing, and the electricity storage unit of the battery product.
