Solution Overview

Problem

Conventional locker management systems face challenges in maximizing the turnover rate of delivery lockers, leading to inefficiencies and increased costs due to unused or underutilized lockers.

Innovation Solution

A locker management system that includes a management server for tracking the status of item shipping from distribution centers to locker spots, and a spot terminal for managing the availability and usage of electronically controlled lockers. The system allows customers to select and designate locker spots and the duration for which items are kept, enabling flexible management and increased utilization of lockers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If lockers are kept occupied for longer periods to accommodate customer pickup schedules, then customer convenience is improved, but locker turnover rate decreases

Engineering Contradiction:
Improvecustomer convenienceVSAvoidlocker turnover rate
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The system dynamically adjusts locker availability based on real-time status and customer requests. Lockers transition between occupied, available, and reserved states based on automated monitoring and customer pickup actions, optimizing both convenience and turnover rate through flexible state management

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system continuously monitors locker status and provides real-time feedback to both customers and the management system. This feedback loop enables automated decisions about locker allocation and release, balancing customer convenience with efficient turnover by notifying customers when items are ready and automatically managing locker states

Inventive Principle:
Principle #23Feedback

2Reliability

If more lockers are installed to ensure availability, then locker availability improves, but installation cost and area requirements increase

Engineering Contradiction:
Improvelocker availabilityVSAvoidinstallation cost
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The locker system is designed to serve multiple functions: storing items during delivery, holding items for customer pickup, and automatically releasing lockers when items are ready. This multi-functionality maximizes the utilization of each locker, reducing the total number needed while maintaining high availability

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system performs preliminary actions by automatically notifying customers when items arrive at lockers and managing locker allocation in advance. This proactive approach ensures lockers are used efficiently and available when needed, reducing the requirement for excess locker capacity

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If lockers are reserved for extended periods to accommodate delayed pickups, then customer flexibility is improved, but locker utilization efficiency decreases

Engineering Contradiction:
Improvecustomer flexibilityVSAvoidlocker utilization efficiency
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The system dynamically manages locker reservations based on actual customer pickup behavior. Reservation periods are flexible and adjustable, allowing customers to pick up items at their convenience while the system automatically releases lockers when items are collected, optimizing both flexibility and utilization efficiency

Inventive Principle:
Principle #15Dynamics

AI summary

A locker management system including a management server that manages status of shipping of items and status of keeping each of the items at the locker spots. The locker spot is equipped with an electronically controlled locker and a spot terminal, and the management server receives selection and designation of the locker spot to keep the item and designation of predetermined length of time for which the item is kept at the locker spot, and upon delivery of the item to the locker spot, notifies a customer terminal of a locker number. When a customer visits the locker spot and reads an identification code attached to the locker, and transmits this code and the customer ID to the management server, the management server performs necessary checking processing. If the answer of the checking processing is positive, the management server transmits a signal for unlocking a locker to the locker.
