Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If cells operate at low temperatures, then energy storage capacity is maintained, but charging and discharging speed decreases and safety is compromised

Engineering Contradiction:

Improvecharging and discharging speedVSAvoidlow temperature operation

Core Design Contradiction:

ProductivityVSTemperature

Solution Approach 1:

The heating base pre-heats the battery cells before charging or discharging operations begin. The temperature sensing mechanism detects low temperature conditions and activates the heating base in advance, warming the cells to an optimal temperature range before the main charging/discharging process starts, thereby ensuring both speed and safety from the outset

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The heating base acts as an intermediary device between the low-temperature environment and the battery cells. It mediates the temperature condition by providing controlled heating, allowing the cells to operate at optimal temperatures even when the external environment is cold, thus resolving the conflict between maintaining energy storage capacity and achieving fast charging/discharging

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If heating is applied to cells at low temperatures, then charging and discharging performance improves, but energy consumption increases

Engineering Contradiction:

Improvecharging and discharging efficiencyVSAvoidenergy consumption for heating

Core Design Contradiction:

ProductivityVSUse of energy by moving object

Solution Approach 1:

The temperature sensing mechanism continuously monitors the cell temperature and provides feedback to the control system. When cells reach the optimal temperature range for charging/discharging, the feedback signal automatically stops or reduces heating, ensuring that energy is not wasted on unnecessary heating while still achieving the required performance improvement

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The heating base applies heating only partially - specifically targeted at the battery cells that need it, and only for the duration necessary to reach optimal operating temperature. This partial action approach avoids excessive energy consumption by limiting heating to the minimum required amount to improve charging/discharging efficiency

Inventive Principle:

Principle #16Partial or excessive action
