Solution Overview

Problem

Electric vehicles equipped with cooling boxes face challenges in maintaining refrigerated or frozen conditions while traveling, as the battery power is often insufficient to cover both refrigeration needs and travel distance, leading to concerns about reaching the destination with perishable goods.

Innovation Solution

A notification system integrated with an electric vehicle, including a cooling box, battery, and RF tags, which acquires storage information and sends warning signals to the user if the travel distance with refrigerated or frozen goods is shorter than a predetermined distance, ensuring timely notification and preventing reduced travel range.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the electric vehicle operates the cooling box to preserve commodities under refrigerated or frozen conditions, then the storage function is improved, but the travelling distance that can be covered becomes shorter due to increased power consumption

Engineering Contradiction:
Improvecommodity preservationVSAvoidtravelling distance
Core Design Contradiction:
ReliabilityVSLength of moving object

Solution Approach 1:

The notification device provides advance warning to the user before the battery power becomes insufficient, allowing the user to take preliminary actions such as adjusting the cooling box settings, reducing power consumption, or planning alternative routes. This prevents the situation where the vehicle runs out of power while maintaining commodity preservation.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The notification system establishes a feedback loop that continuously monitors battery power levels and communicates the impact on travelling distance to the user. This feedback enables the user to make informed decisions about power management and commodity preservation, balancing the two competing requirements.

Inventive Principle:
Principle #23Feedback

2Reliability

If the electric vehicle increases battery power allocation to the cooling box, then the commodity preservation reliability is improved, but the available power for travelling is reduced

Engineering Contradiction:
Improvecooling box operationVSAvoidpower availability for travel
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The notification device may suggest partial actions such as adjusting the cooling box to operate at reduced capacity, using intermittent cooling cycles, or maintaining higher temperatures than ideal for shorter periods. These partial measures allow the vehicle to travel farther while still providing adequate commodity preservation for the journey.

Inventive Principle:
Principle #16Partial or excessive action

AI summary

The notification system includes: an electric vehicle provided with a cooling box, a battery, and wheels driven by the electric power from the battery; an acquisition device configured to obtain storage information indicating storage conditions for a commodity selected by a user; a processor configured to send a warning signal when a travelling distance which can be covered by the electric vehicle with the selected commodity being preserved in the cooling box under the storage conditions indicated by the storage information is shorter than a predetermined distance; and a notification device configured to notify the user of a warning upon receiving the warning signal.
