Management Device for Proportional CO2 Emission Calculation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for calculating CO2 emissions from product production do not accurately account for emissions during the transportation process, especially when multiple products are consolidated on a moving object, leading to incomplete carbon footprint assessments.
Innovation Solution
A management device and method that calculates CO2 emissions by storing energy consumption data and using a weight ratio to proportionally divide energy consumption between consolidated products, converting this energy into CO2 emissions using established conversion formulas.

1Productivity
If multiple products are consolidated on a moving object for transportation, then transportation efficiency is improved, but accurate calculation of CO2 emissions for each product becomes difficult
Solution Approach 1:
The patent segments the total CO2 emissions into distinct components: fixed emissions (independent of load) and variable emissions (proportional to product weight). By dividing the emission calculation into these segments, the system can accurately attribute emissions to each consolidated product based on its weight ratio, resolving the measurement precision issue while maintaining consolidation benefits
Solution Approach 2:
The patent introduces a weight ratio parameter to dynamically allocate variable CO2 emissions among consolidated products. By changing the calculation approach from uniform distribution to weight-proportional distribution, the system achieves accurate emissions attribution that reflects the actual energy consumption pattern of each product during consolidated transportation
2Ease of manufacture
If CO2 emissions are calculated based on total energy consumption without product differentiation, then calculation simplicity is improved, but environmental accountability for individual products deteriorates
Solution Approach 1:
The patent segments the total energy consumption into fixed and variable components, where fixed energy consumption generates fixed emissions and variable energy consumption generates variable emissions. This segmentation allows the system to maintain calculation simplicity while preserving product-specific emissions information through weight ratio-based allocation of the variable portion
Solution Approach 2:
The patent applies a weight ratio parameter to the variable emissions portion to differentiate emissions among products. This parameter change enables the system to transition from a simple total-emissions calculation to a differentiated calculation that maintains ease of use while preventing loss of product-specific emissions information

AI summary
A control device reads power consumption, information on the delivery number and weight of a first product set, and information on the delivery number and weight of a second product set from a storage device. The control device proportionally divides the power consumption. The control device reads a first conversion formula from the storage device, and calculates CO2 emissions from transportation of the first product set from an A station to a B station and CO2 emissions from transportation of the second product set from the A station to the B station by substituting the power consumptions, into the first conversion formula.
