Solution Overview

Problem

Existing drawer side frames are not stable and complicate the assembly process, particularly when dealing with bases of different thicknesses, as they often result in damage due to protruding stops and uneven surfaces.

Innovation Solution

A side frame design featuring a support rail with a horizontal web and vertical wall section, including adapters with guide tabs that allow the floor to be aligned and moved along the vertical wall without hitting the adapters, ensuring smooth assembly by providing a stepless guidance mechanism.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a projecting stop is provided on the vertical wall section to assist with mounting bottoms of varying thicknesses, then adaptability to different base thicknesses is improved, but the base may be stopped against the stop during insertion, complicating installation and potentially leading to damage

Engineering Contradiction:
Improveadaptability to different base thicknessesVSAvoidease of installation
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The guide tab acts as an intermediary element between the base and the adapter. It provides a smooth guiding surface that directs the base into the correct position without the base directly contacting the adapter's edge, thus preventing damage while maintaining adaptability to different thicknesses

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The guide tab is pre-formed on the vertical wall section to create a stepless transition surface before the base reaches the adapter. This preliminary guiding action prevents the base from striking the adapter during insertion, eliminating the need for corrective actions during installation

Inventive Principle:
Principle #10Preliminary action

2Reliability

If the adapter edge is exposed on the vertical wall section, then the adapter can be securely fixed to the support rail, but the base may strike or be damaged by the adapter during insertion

Engineering Contradiction:
Improvesecure fixation of adapterVSAvoiddamage to base during installation
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The guide tab serves as a protective intermediary that covers the exposed edge of the adapter. It allows the base to be guided safely into position without directly contacting the potentially harmful adapter edge, thus preventing damage while the adapter remains securely fixed

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The guide tab provides a cushioning effect by creating a stepless transition that prevents the base from striking the adapter. This protective measure is built into the structure beforehand, eliminating the risk of damage during the insertion process

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

3Ease of operation

If a stepless guidance mechanism is implemented using a guide tab, then the ease of assembly is improved, but the device complexity increases due to additional structural elements

Engineering Contradiction:
Improveease of assemblyVSAvoidstructural complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The guide tab is integrally formed with the support rail structure, merging the guidance function into the existing component rather than adding a separate part. This reduces assembly steps while providing the necessary stepless guidance mechanism

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The guide tab is only formed in the specific local area where guidance is needed on the vertical wall section. This localized modification provides the necessary guidance function without significantly increasing the overall complexity of the entire support rail structure

Inventive Principle:
Principle #3Local quality

AI summary

The invention relates to a side panel (1) for a drawer comprising a carrier rail (2), on which a horizontal support strip (7) for a base (16) and a vertical wall section (8) is formed, wherein at least one adapter (3, 4) is secured to the vertical wall section (8), on which a cover (5, 6) and/or a wall element can be fixed, wherein a guide tab (12, 13, 32) is arranged on the vertical wall section (8) next to the at least one adapter (3, 4), which covers at least one part of an edge of the adapter (3, 4). In this way, the assembly of the base (16) on the carrier rail (2) is simplified.
