Solution Overview

Problem

Epoxy glides in drawer mechanisms often result in rough, uneven movement due to single rollers and loose fits, while ball bearing glides are costly and labor-intensive, making them unsuitable for mass production in kitchen and bathroom cabinetry, and they struggle with warped or misshapen drawers.

Innovation Solution

A drawer glide mechanism incorporating a v-notch socket with a first elongate guide member and a nested second elongate guide member, featuring a ball bearing component for smooth movement and adjustable floating and fixed members to accommodate warped drawers, allowing for easy installation and adjustment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If epoxy glides with single rollers are used, then cost is reduced, but drawer movement becomes rough and uneven

Engineering Contradiction:
ImprovecostVSAvoiddrawer movement smoothness
Core Design Contradiction:
Ease of manufactureVSEase of operation

Solution Approach 1:

The patent employs a nested structure with an inner guide member positioned within an outer guide member, both containing rollers that contact the drawer. This nested arrangement allows multiple rollers to work together at different positions, providing smooth drawer movement while maintaining the cost-effectiveness of using standard epoxy glide components.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The drawer glide mechanism is divided into separate functional segments: an outer guide member with outer rollers, an inner guide member with inner rollers, and a drawer connector. This segmentation allows each component to be manufactured independently using standard epoxy glide processes, keeping costs down while the coordinated operation of all segments delivers smooth movement.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If ball bearing guide members are used, then drawer movement smoothness is improved, but cost and labor increase

Engineering Contradiction:
Improvedrawer movement smoothnessVSAvoidcost and labor
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

The patent replaces expensive ball bearing components with multiple standard epoxy glide rollers arranged in a nested configuration. These conventional rollers, while individually simpler, work together to provide ball bearing-level smoothness at a fraction of the cost and complexity, making the solution ideal for mass production in kitchen and bathroom cabinetry.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The nested guide members and rollers are designed to dynamically interact during drawer operation. The inner and outer rollers work in coordination, with their relative positions and contact points optimizing smooth movement throughout the drawer's travel range, achieving ball bearing performance without the associated cost and manufacturing complexity.

Inventive Principle:
Principle #15Dynamics

3Ease of operation

If ball bearing glides are used, then drawer movement smoothness is improved, but device complexity increases

Engineering Contradiction:
Improvedrawer movement smoothnessVSAvoidstructure complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The nested guide members serve multiple functions simultaneously: they guide drawer movement, support roller rotation, accommodate variations in drawer alignment, and provide structural stability. This multi-functionality is achieved using standard epoxy glide components rather than specialized ball bearing assemblies, reducing overall device complexity while maintaining smooth operation.

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

Solution Approach 2:

The nested arrangement of guide members and rollers creates a compact, integrated structure where the inner guide member fits within the outer guide member. This nesting reduces the overall footprint and simplifies installation compared to separate ball bearing components, while the coordinated rollers provide the smooth movement characteristic of more complex mechanisms.

Inventive Principle:
Principle #7Nested doll (Nesting)

4Ease of manufacture

If standard v-notch sockets are used, then installation simplicity is improved, but adaptability to warped drawers decreases

Engineering Contradiction:
Improveinstallation simplicityVSAvoidaccommodation of warped drawers
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The drawer connector is designed with dynamic adjustment capabilities, allowing it to adapt to warped or misaligned drawers during installation and operation. The connector can accommodate variations in drawer geometry while maintaining proper engagement with the nested guide members, preserving both installation simplicity and adaptability to non-ideal drawer conditions.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The separation of the drawer connector from the nested guide members allows independent optimization of each component. The v-notch sockets can remain simple for easy installation, while the connector design specifically addresses adaptability to warped drawers through its joint configuration and mounting geometry.

Inventive Principle:
Principle #1Segmentation

AI summary

A drawer glide mechanism can include a first elongate guide member, a second elongate guide member, a ball bearing component, a v-notch socket, a release mechanism, and/or a roller support. The first elongate guide member can include a distal end that is configured to fit within an opening in the v-notch socket. The drawer glide mechanism can further include one or more floating members and fixed members. In some cases, the drawer glide mechanism includes a release member configured to facilitate separation of the first and second elongate guide members when actuated and to inhibit or prevent accidental separation of the first and second elongate guide members.
