Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing CO2 capturing systems in vehicles face inefficiencies in desorbing CO2 due to insufficient heat generated by the engine, leading to incomplete CO2 discharge into storage stations.
Innovation Solution
A control system that utilizes a controller to manage energy sources within the vehicle, including thermal energy from a heat accumulator, to desorb CO2 from the capturing device and ensure complete discharge, with the option to receive additional energy from an external recovery station if internal energy is insufficient, and incentivizes CO2 discharge by offering compensation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If CO2 is captured by the capturing agent during engine operation, then CO2 capture is achieved, but the engine heat is insufficient to fully desorb CO2 from the capturing agent
Solution Approach 1:
The patent combines multiple heat sources (engine waste heat and external power station heat) into a unified desorption system. The control unit manages heat input from both the engine and external power station to the thermal energy storage device, which then supplies sufficient thermal energy to the capturing agent for complete CO2 desorption, resolving the contradiction between CO2 capture quantity and desorption temperature requirement
Solution Approach 2:
The patent introduces a thermal energy storage device as an intermediary between the heat sources (engine and external power station) and the capturing agent. This intermediary stores thermal energy and releases it at the appropriate time and temperature level required for effective CO2 desorption, bridging the gap between insufficient engine heat and the high temperature needed for complete desorption
2Reliability
If engine heat is used to desorb CO2, then energy self-sufficiency is maintained, but CO2 discharge is incomplete when engine heat is insufficient
Solution Approach 1:
The patent implements a dynamic energy management system where the control unit continuously monitors and adjusts the ratio of heat input from the engine versus external power station based on real-time conditions. This dynamic adjustment ensures complete CO2 discharge by optimizing the energy source mix, maintaining reliability while managing energy consumption flexibly according to available resources
Solution Approach 2:
The patent changes the energy supply parameters by introducing external power station heat as an additional energy source. The control unit regulates the amount of external heat input to complement engine heat, ensuring that the total thermal energy supplied to the capturing agent is sufficient for complete CO2 desorption, thereby improving discharge completeness without excessive energy consumption

Function Achieved in This Case
Ensures complete and efficient discharge of CO2 into recovery stations, reducing global warming by effectively utilizing waste heat and motivating consumers and drivers to collect CO2, while minimizing external energy consumption.
Implementation Method 1
CO2 emitted from an internal combustion engine and CO2 in the air are recovered by a capturing material disposed at a through channel of gas
Implementation Method 2
exhaust gas emitted from an engine is supplied to a capture agent to capture CO2 contained in the exhaust gas
Implementation Method 3
The captured CO2 is desorbed from the capturing material by heat generated from the internal combustion engine
Implementation Method 4
the CO2 captured by the conventional capturing system is heated by the engine's waste heat to be desorbed from the capture agent
