Innovation Solution

A method utilizing standardized transport containers with RFID tags, managed by a control system, that automates the delivery process through an elevator system with detectors and sub-control systems to optimize the flow of goods to their destination floors, minimizing traffic and ensuring timely delivery.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If diverse different means and methods for transportation are used in a relatively unsystematic manner, then various goods can be transported to different floors, but the transportation process becomes inefficient and causes delays

Engineering Contradiction:
Improvetransportation means diversityVSAvoidtransportation efficiency
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The system segments the transportation process into standardized modules: uniform transport containers with RFID tags, dedicated elevator shafts, and automated control subsystems. Each component is standardized and can be independently optimized, yet they work together as an integrated system, resolving the contradiction between versatility and efficiency.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The elevator system is designed to serve multiple functions: transporting construction materials during construction phases and later serving as a passenger elevator for the completed building. The standardized container system can accommodate various types of goods while following uniform protocols, achieving both versatility and efficiency.

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

2Speed

If goods are transported using temporary hoist arrangements and construction time elevators, then delivery to upper floors is enabled, but traffic congestion and scheduling difficulties occur

Engineering Contradiction:
Improvevertical transport capabilityVSAvoiddelivery delays
Core Design Contradiction:
SpeedVSLoss of time

Solution Approach 1:

The system incorporates RFID detectors that automatically track container locations and a central control system that monitors elevator status, container destinations, and scheduling information. This feedback mechanism enables real-time optimization of transport routes and timing, preventing congestion and delays while maintaining high vertical transport capability.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

Containers are equipped with RFID tags that pre-identify their destination floors and contents. The control system receives and processes this information in advance, allowing elevators to be scheduled and dispatched proactively rather than reactively, thereby eliminating waiting times and delivery delays.

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If manual scheduling and coordination of transportation is performed, then flexibility in handling different goods is maintained, but the process becomes complex and error-prone

Engineering Contradiction:
Improvescheduling flexibilityVSAvoidcoordination complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The system employs automated self-service mechanisms where RFID detectors automatically identify containers, the control system autonomously schedules elevator dispatch based on destination and priority, and the system self-coordinates to prevent conflicts. This automation maintains operational flexibility while eliminating the complexity and errors associated with manual scheduling.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical coordination processes with an electronic control system that uses RFID technology for automatic identification and tracking. This substitution transforms the complex manual scheduling task into an automated electronic decision-making process, reducing operational complexity while maintaining or enhancing flexibility.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

4Extent of automation

If standardized transport containers with RFID tags are used, then automated tracking and delivery optimization is enabled, but initial setup and equipment costs increase

Engineering Contradiction:
Improvetransport monitoring automationVSAvoidimplementation cost
Core Design Contradiction:
Extent of automationVSEase of manufacture

Solution Approach 1:

The standardized containers serve dual purposes: they are used during construction for material transport and later can be adapted for use in the completed building's logistics or storage systems. The RFID tags and detection infrastructure support both construction-phase automated tracking and post-construction operations, amortizing the initial investment over multiple operational phases and reducing overall implementation cost.

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