Solution Overview

Problem

Existing automated stock control systems require different sizes of supports for drawers of varying sizes, leading to increased manufacturing costs, assembly time, and complexity due to the need for multiple fastening methods and components.

Innovation Solution

A support component with a resilient leg and engagement protrusions that can be easily attached and removed from panels without screws, allowing for the same component to support different sized drawers by adjusting the position of a projecting rib, reducing the need for multiple support sizes and simplifying assembly and reconfiguration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If different sizes of supports are used to support drawers of different sizes, then the stability of the drawer is improved, but the device complexity and manufacturing cost increase

Engineering Contradiction:
Improvedrawer stabilityVSAvoidsupport component variety
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The support component is designed with a resilient leg that can flex to accommodate different drawer sizes and weights. The same support component can be used for both standard and large drawers, eliminating the need for multiple support sizes. The resilient leg adapts its deflection based on the load, providing universal applicability across different drawer configurations.

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

Solution Approach 2:

The support component uses a resilient leg whose physical properties (flexibility, deflection) change based on the applied load. This allows a single component to provide appropriate support for different drawer sizes by dynamically adjusting its mechanical response rather than requiring different rigid support structures.

Inventive Principle:
Principle #35Parameter changes

2Strength

If screws are used to attach the support to the panel, then the strength of the connection is improved, but the ease of manufacture and assembly time worsen

Engineering Contradiction:
Improveconnection strengthVSAvoidassembly time
Core Design Contradiction:
StrengthVSEase of manufacture

Solution Approach 1:

The support component features a self-latching mechanism with an engagement protrusion that automatically secures to the panel when the resilient leg is compressed. This eliminates the need for separate fastening operations with screws, allowing the support to attach itself to the panel through simple compression and release actions during assembly.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The screw fastening mechanism is completely removed from the design. Instead of requiring separate fasteners, the support component integrates its attachment function directly into the resilient leg structure, which both supports the drawer and secures to the panel in a single unified mechanism.

Inventive Principle:
Principle #2Taking out (Extraction)

3Ease of manufacture

If the support is designed for standard drawer sizes, then the manufacturing cost is reduced, but the adaptability to different drawer sizes worsens

Engineering Contradiction:
Improvemanufacturing costVSAvoiddrawer size compatibility
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The support component is designed as a universal solution that works with both standard and large drawers. The resilient leg's flexibility allows it to accommodate various drawer weights and sizes without requiring different support components, achieving both cost efficiency and versatility.

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

Solution Approach 2:

The support component transitions from a static, fixed-position support to a dynamic, adaptable support. The resilient leg can deflect and adjust its position dynamically based on the drawer size and weight, allowing a single component design to serve multiple drawer configurations that would traditionally require different static support structures.

Inventive Principle:
Principle #15Dynamics
