Solution Overview

Problem

Existing drawer dividers are complex and costly to assemble, requiring multiple parts and significant time due to separate components and intricate mechanisms, making them inefficient for adaptation to different drawer dimensions.

Innovation Solution

A drawer divider design featuring a single-piece plastic clamping piece with integrated spring bars, allowing for compact and stable assembly with adjustable clamping travel, and a hollow profile partition that can be easily adapted to various drawer sizes using transverse divider clamping pieces.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple separate parts and intricate mechanisms are used in drawer dividers, then the clamping function can be achieved, but the assembly complexity and manufacturing cost increase significantly

Engineering Contradiction:
Improveclamping functionVSAvoidassembly complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the plug-in section, spring element, and contact section into a single integrated clamping piece. This merging of previously separate components (plug, spring, and contact part) into one monolithic structure reduces the number of parts that need to be assembled while maintaining the complete clamping function, directly resolving the contradiction between reliability and assembly complexity

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If multiple separate parts are used in drawer dividers, then the clamping function can be achieved, but the assembly time and effort increase significantly

Engineering Contradiction:
Improveclamping functionVSAvoidassembly time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

By integrating the spring element, plug-in section, and contact section into a single clamping piece, the patent eliminates the need to assemble multiple separate components. This single-piece design allows for rapid installation into the partition opening without the time-consuming process of assembling multiple parts, directly addressing the time loss issue

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If separate components are used in drawer dividers, then the clamping function can be achieved, but the manufacturing cost increases significantly

Engineering Contradiction:
Improveclamping functionVSAvoidmanufacturing cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent manufactures the clamping piece as a single injection-molded plastic component that integrates the spring element, plug-in section, and contact section. This consolidates multiple manufacturing operations into one process, reducing tooling costs, assembly costs, and inventory management costs while maintaining the full clamping function

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent transitions from using metal springs and separate metal/plastic components to using a plastic spring element integrated into a plastic clamping piece. This material and structural parameter change simplifies manufacturing and reduces costs while maintaining functional performance

Inventive Principle:
Principle #35Parameter changes

AI summary

The divider (10) has a partition wall (11) whose two ends are arranged with a front-sided aperture (16), and a springy clamping piece (12) including a plug-in section (17) that is placed in the front-sided aperture and rests with a stop part outside at a front side of the partition wall. An arrangement portion (18) is arranged at a drawer wall. The arrangement portion is movable toward the section against return force of a spring element. The spring element is formed through a spring bar that is formed as a one-piece plastic part together with the section and the arrangement portion.
