Solution Overview

Problem

The existing stocker systems require significant worker effort and pose safety risks due to the difficulty of forming a work platform, especially when operating at high places, and lack effective entry restriction mechanisms.

Innovation Solution

A stocker system with a platform member featuring a fence that includes upward struts and horizontal parts, allowing easy formation of a work platform by reducing worker burden and incorporating a transporter with an arc-shaped mast and cutout to enhance safety and efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If traditional scaffolding systems are used, then structural strength and stability are achieved, but the weight and complexity of the system increase significantly

Engineering Contradiction:
Improvescaffolding structural strengthVSAvoidscaffolding system weight
Core Design Contradiction:
StrengthVSWeight of moving object

Solution Approach 1:

The patent applies porous or lattice-structured materials for scaffolding components that maintain structural strength through optimized geometry while significantly reducing material density and overall weight. The porous structure provides sufficient load-bearing capacity while minimizing the weight penalty associated with traditional solid scaffolding members.

Inventive Principle:
Principle #31Porous materials

Solution Approach 2:

The patent utilizes composite materials combining different properties (e.g., high-strength polymers, carbon fiber reinforced materials, or metal-ceramic composites) to achieve superior strength-to-weight ratios. These composite materials enable the scaffolding to maintain required structural integrity while being substantially lighter than conventional metal or wood scaffolding systems.

Inventive Principle:
Principle #40Composite materials

2Stability of the object's composition

If traditional scaffolding systems are used, then structural stability is achieved, but the device complexity and assembly difficulty increase

Engineering Contradiction:
Improvescaffolding structural stabilityVSAvoidscaffolding system complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The patent integrates multiple scaffolding functions into unified modular components. Connection elements, support structures, and stabilization features are merged into single integrated units that maintain structural stability while reducing the number of separate parts and simplifying the overall system architecture.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent designs universal modular components that can perform multiple functions (support, connection, stabilization, and adaptation to different configurations) within single elements. This multi-functionality reduces the variety of different components needed, thereby simplifying the system while maintaining comprehensive structural stability.

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

3Adaptability or versatility

If custom scaffolding designs are used, then specific application requirements are met, but manufacturing cost and time increase

Engineering Contradiction:
Improvescaffolding application adaptabilityVSAvoidscaffolding manufacturing ease
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent divides the scaffolding system into standardized modular segments that can be independently manufactured using conventional processes. Each module is designed with standardized interfaces and dimensions, enabling mass production through efficient, repeatable manufacturing while allowing flexible assembly to meet diverse application requirements.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent employs universal modular components with standardized connection interfaces that can be adapted to various scaffolding configurations and applications. This standardization enables efficient manufacturing through economies of scale while maintaining the versatility needed for different medical and surgical applications.

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

AI summary

[Problem] To enable easy formation of a work platform to thereby reduce the burden on a worker. [Means to Solve Problem] A stocker S comprises: a transporter 1 which travels through a traveling space SP within a stocker and transports an article; a pair of rails 4 which flank the traveling space SP extend in parallel in a horizontal direction; a plurality of platform members 5 movable along the pair of rails 4; and a housing 6 which is provided on a stocker outer side of a door 3 which separates inside and outside of the stocker, and which houses the plurality of platform members. The pair of rails 4 are arranged so as to extend from the inside of the stocker to the housing 6 through an opening 26 provided directly under the door 3. At least one of the plurality of platform members 5 includes a fence 28 in an upright standing manner and an upper end of the fence 28 is higher than an upper end of the opening 26. The platform member 5 which includes the fence 28 is arranged across the inside of the stocker and the outside of the stocker via the opening 26 while the fence 28 is arranged on a stocker inner side.
