Solution Overview

Problem

The existing trunk share systems face inefficiencies in parcel delivery operations due to the vehicle's unsuitability as a delivery destination for certain packages, such as frozen products, which can degrade in quality when left in the vehicle, and the need for direct delivery to recipients, leading to potential redelivery issues.

Innovation Solution

An information processing system that acquires package attribute information and surrounding environment data to determine if a vehicle is suitable as a collection and delivery point, considering factors like temperature, sunlight, and recipient presence, and includes a notification system to ensure packages are delivered to the recipient directly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a vehicle is designated as a collection and delivery place for all packages, then the convenience and flexibility of the delivery system is improved, but the quality of temperature-sensitive packages (such as frozen products) deteriorates due to unsuitable environmental conditions in the vehicle

Engineering Contradiction:
Improveflexibility of delivery systemVSAvoidquality degradation of frozen products
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The system evaluates specific local conditions (vehicle environment attributes such as temperature control capability, sunlight exposure, and duration of storage) against package requirements to determine suitability. This allows different parts of the delivery system (vehicle vs. other locations) to be optimized for different package types, preventing quality degradation of temperature-sensitive items while maintaining vehicle availability for appropriate packages.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system performs preliminary evaluation of vehicle suitability based on package attributes before delivery assignment. By assessing whether the vehicle environment is appropriate for the specific package type in advance, the system prevents quality degradation from occurring, allowing flexible vehicle usage for suitable packages while redirecting unsuitable packages to alternative locations.

Inventive Principle:
Principle #10Preliminary action

2Productivity

If the system automatically determines vehicle suitability based on package attributes, then delivery efficiency is improved by preventing quality issues, but the system complexity increases due to additional determination processes

Engineering Contradiction:
Improvedelivery efficiencyVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system uses automated rule-based determination that evaluates package attributes against pre-defined vehicle suitability criteria without requiring manual intervention. This self-service approach improves delivery efficiency by automatically preventing unsuitable deliveries while maintaining manageable system complexity through standardized evaluation rules rather than complex algorithms.

Inventive Principle:
Principle #25Self-service

3Measurement precision

If the system considers surrounding environment conditions in addition to package attributes, then the accuracy of vehicle suitability determination is improved, but the information processing requirements and system complexity increase

Engineering Contradiction:
Improveaccuracy of suitability determinationVSAvoidinformation processing requirements
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system collects and evaluates surrounding environment conditions (such as parking location, sunlight exposure, ambient temperature) in advance of delivery assignment, combining this information with package attributes to make accurate suitability determinations. This preliminary gathering of environmental data improves determination accuracy while managing information processing requirements through structured data collection protocols.

Inventive Principle:
Principle #10Preliminary action

AI summary

An information processing system includes: an acquisition portion configured to acquire pieces of attribute information of a first package; a controlling portion configured to perform a determination process of determining whether or not a first vehicle is suitable as a collection and delivery place for the first package based on package attribute condition information that is included in the attribute information of the first package, the package attribute condition information being related to an attribute of the first package as one of determination conditions based on which the first vehicle is determined to be suitable as the collection and delivery place; and an output portion configured to output a result of the determination process.
