Solution Overview

Problem

Existing automated stock control systems face challenges in modifying drawer configurations to meet customer needs, have low storage density due to space-consuming trays or carriers, and are expensive to manufacture and maintain.

Innovation Solution

A modular storage system with cartridges that hold multiple drawers, each equipped with a guide block and solenoid latch mechanism, allowing for easy removal and reconfiguration of drawers without requiring access to the rear of the housing, and enabling flexible adjustment of drawer widths and heights.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If trays or movable carriers are used to hold drawers, then the drawers can be supported and guided, but the storage density decreases due to the space occupied by these trays and carriers

Engineering Contradiction:
Improvedrawer support and guidanceVSAvoidstorage density
Core Design Contradiction:
Stability of the object's compositionVSQuantity of substance

Solution Approach 1:

The patent extracts the drawer support and guidance function from separate trays or carriers and integrates it directly into the housing structure. Guide blocks are mounted to the housing to engage with grooves in the drawers, providing support and guidance without requiring additional tray structures. This eliminates the space-consuming intermediate carriers while maintaining drawer stability.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent merges the support and guidance functions with the housing structure itself. The guide blocks are attached to the housing and work in conjunction with the drawer grooves to provide stable support. This consolidation eliminates redundant components (separate trays and carriers) and maximizes storage density by using the housing structure for multiple functions.

Inventive Principle:
Principle #5Merging (Combining)

2Adaptability or versatility

If separate latch mechanisms with separate control circuitry are provided for each drawer, then each drawer can be independently controlled, but the device complexity increases

Engineering Contradiction:
Improveindependent drawer controlVSAvoidlatch mechanism and control circuitry
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent employs a universal latch mechanism design where a single type of solenoid-actuated latch can be used for multiple drawers. The latch mechanism is standardized and can control different drawers through a common control system, reducing the variety of components needed while maintaining independent control capability.

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

Solution Approach 2:

The patent introduces a control system that acts as an intermediary between the user and the latch mechanisms. The controller receives access requests and selectively actuates the appropriate solenoids to release specific drawers. This centralized control approach simplifies the overall system by reducing the number of independent control circuits needed while maintaining individual drawer accessibility.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of manufacture

If drawers are removed by accessing the rear of the housing, then the drawers can be released from carriers, but the ease of operation decreases

Engineering Contradiction:
Improvedrawer removal capabilityVSAvoiddrawer removal accessibility
Core Design Contradiction:
Ease of manufactureVSEase of operation

Solution Approach 1:

The patent inverts the traditional drawer removal approach by allowing drawers to be removed from the front of the housing rather than requiring access to the rear. The guide blocks are designed to disengage from the drawer grooves when the drawer is pulled forward, enabling front-access removal. This reversal of the removal direction significantly improves operational ease while maintaining the structural integrity of the system.

Inventive Principle:
Principle #13The other way round (Inversion)

4Adaptability or versatility

If modification of drawer layout is required, then the system can be adapted to customer needs, but the manufacturing cost increases due to redesign requirements

Engineering Contradiction:
Improvedrawer layout flexibilityVSAvoidmanufacturing cost
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent segments the storage system into modular components: the housing, guide blocks, drawers with standardized grooves, and latch mechanisms. This segmentation allows individual drawers to be easily added, removed, or reconfigured without requiring redesign of the entire system. The standardized interface between guide blocks and drawer grooves enables flexible layout modifications while maintaining manufacturing efficiency through component reusability.

Inventive Principle:
Principle #1Segmentation
