Solution Overview

Problem

The challenge of efficiently collecting a needed number of batteries for secondary usage is hindered by the difficulty in coordinating the collection of multiple batteries from various vehicles within a limited time frame, leading to potential waste if not collected within three months, due to maintenance of battery quality.

Innovation Solution

An information processing device with a control unit that acquires and processes first and second user information, including time limits, positions, materials, and deterioration levels, to transmit notifications to second users with adjusted conditions such as price, region, material, and deterioration criteria based on the time limit, facilitating easy collection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the system transmits notifications to all second users regardless of conditions, then the collection process is simple, but the time required to collect batteries increases and quality maintenance becomes difficult

Engineering Contradiction:
Improveease of battery collectionVSAvoidtime limit for battery collection
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The notification transmission is dynamically adjusted based on multiple parameters including time limits, battery quality requirements, user positions, and battery specifications. The control unit selectively transmits notifications to second users whose batteries meet the required conditions, optimizing both collection efficiency and quality maintenance within time constraints.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The system dynamically determines notification transmission based on real-time conditions such as current time versus time limits, battery status, and user availability. This dynamic approach allows the system to adapt notification strategies to changing conditions, ensuring timely collection while maintaining battery quality standards.

Inventive Principle:
Principle #15Dynamics

2Productivity

If the system adjusts notification conditions based on time limits and battery specifications, then collection efficiency improves, but the system complexity increases

Engineering Contradiction:
Improvebattery collection efficiencyVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The control unit receives first information including time limits and battery specifications, processes this feedback information, and adjusts notification transmission accordingly. This feedback mechanism enables the system to optimize collection efficiency by targeting notifications to appropriate second users based on their battery conditions and the collection requirements.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The notification process is segmented into distinct evaluation stages: checking time limit compliance, verifying battery specification matches, determining user eligibility, and selectively transmitting notifications. This segmentation complexifies the system structure but organizes the complexity into manageable, modular components that improve overall collection efficiency.

Inventive Principle:
Principle #1Segmentation

3Quantity of substance

If the system collects batteries from a wide region, then the available battery pool increases, but the time and cost for collection increase

Engineering Contradiction:
Improvenumber of available batteriesVSAvoidcollection time
Core Design Contradiction:
Quantity of substanceVSLoss of time

Solution Approach 1:

The system evaluates the position information of second users relative to the first user's location and prioritizes notifications to users in closer proximity. By applying local quality principles, the system collects batteries from nearby regions first, reducing transportation time and costs while still achieving sufficient quantity through progressive expansion to farther regions if needed.

Inventive Principle:
Principle #3Local quality
