Solution Overview

Problem

Existing drawer panel adjustment mechanisms only allow for upward and downward movement, failing to align front panels of furniture drawers precisely in the left-right direction, which affects the overall quality perception of furniture.

Innovation Solution

A drawer panel adjusting device featuring a fixed member with limiting blocks, a first movable member with an adjusting hole and spiral block, and a second movable member with a guiding block, enabling the front panel to move upward, downward, leftward, or rightward by utilizing a combination of spiral blocks and guiding grooves for precise alignment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a conventional board connecting mechanism is used for drawer panel adjustment, then upward and downward movement of the front panel is enabled, but leftward and rightward adjustment capability is lost

Engineering Contradiction:
Improveadjustment capabilityVSAvoidmechanism structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The adjustment mechanism is divided into two independent adjustment members: a first adjusting member for upward/downward movement and a second adjusting member for leftward/rightward movement. Each adjustment member has its own control portion and adjusting hole, allowing independent operation for each adjustment direction, thereby achieving multi-directional adaptability without excessive complexity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention transitions from single-direction (vertical only) adjustment to multi-directional (vertical + horizontal) adjustment by introducing a second adjusting member that operates in a different dimensional plane. The second adjusting member's spiral block engages with limiting blocks to enable leftward/rightward movement, adding a new dimension of adjustment capability

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Manufacturing precision

If the front panel position is fixed during assembly, then assembly speed is fast, but alignment precision with other drawers is poor

Engineering Contradiction:
Improvepanel alignment precisionVSAvoidassembly process
Core Design Contradiction:
Manufacturing precisionVSEase of manufacture

Solution Approach 1:

The adjustment members are pre-installed on the drawer frame before the front panel is attached. The control portions of the adjustment members extend through the front panel, allowing alignment adjustments to be made after the panel is in place but before final tightening, ensuring precise alignment without complicating the assembly process

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The first and second adjusting members act as intermediary mechanisms between the drawer frame and the front panel. These adjusters provide controlled movement capability during assembly, allowing the front panel to be precisely positioned in multiple directions before being fixed in place, thereby achieving high alignment precision

Inventive Principle:
Principle #24Intermediary (Mediator)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The device allows for easy and precise adjustment of the front panel's position relative to other boards, enhancing the alignment of drawers and improving the overall quality and aesthetic appeal of furniture by enabling multi-directional movement.

Implementation Method 1

A first adjusting member includes a first side having a first control portion and a second side having a spiral block. A spacing between the spiral block and a central axis of the first adjusting member gradually increases from an end of the spiral block toward the other end of the spiral block.

Methodology Applied
Scientific EffectScrew mechanism: Screw

Implementation Method 2

The second adjusting member includes an outer periphery having a spiral guiding groove. The second adjusting member extends through the second adjusting hole and is restrained in the assembling groove. The guiding block is engaged in the spiral guiding groove.

Methodology Applied
Scientific EffectSpiral guiding mechanism: Screw
