Solution Overview

Problem

Existing drawer front connecting devices are complex, difficult to manufacture, and require significant space, making them unsuitable for all drawer designs and posing challenges in adjusting the drawer front's position relative to the side frame, especially for heavy or large fronts.

Innovation Solution

A drawer adjustment device comprising a housing, a spring element, an adjusting element, and a locking arrangement, where the adjusting element is rotatably mounted on the housing, allowing for lateral and height adjustments of the drawer front, with a locking element that moves between positions to secure the adjustment, enabling simple and secure height adjustment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a robust adjustment device is used to ensure safe functioning, then reliability is improved, but device complexity increases

Engineering Contradiction:
Improvesafe functioning of adjustment optionsVSAvoidcomplicated and robust construction
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The adjustment device is segmented into distinct functional modules: a locking element for securing positions, an adjusting element for movement, and a spring element for providing force. This segmentation allows each component to be optimized independently while maintaining overall reliability without excessive complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The adjustment device incorporates dynamic elements including a rotatably mounted adjusting element that enables lateral and height adjustments, and a locking element that can move between locked and unlocked states. This dynamic design provides reliable adjustment functionality while maintaining structural efficiency.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If a multi-part structure is used to provide adjustment options, then adaptability is improved, but manufacturing complexity increases

Engineering Contradiction:
Improveadjustment options for drawer front positionVSAvoidcomplicated to manufacture
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The adjustment device is designed as a universal component that can be applied to various drawer configurations. The housing can be mounted on drawer side parts, and the front connector can be attached to drawer fronts of different sizes and weights, providing versatile adjustment capability without requiring multiple specialized components.

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

Solution Approach 2:

Multiple adjustment functions (lateral adjustment, height adjustment) are merged into a single integrated device comprising a housing, locking element, adjusting element, and spring element. This consolidation reduces the number of separate parts that need to be manufactured and assembled compared to traditional multi-component adjustment systems.

Inventive Principle:
Principle #5Merging (Combining)

3Strength

If a robust connecting device is used to absorb high forces, then strength is improved, but space requirements increase

Engineering Contradiction:
Improveforces absorbed by connecting deviceVSAvoidfree space on drawer side parts
Core Design Contradiction:
StrengthVSArea of stationary object

Solution Approach 1:

The adjustment device components are nested within a compact housing structure. The locking element, adjusting element, and spring element are arranged in a space-efficient configuration within the housing, allowing the entire adjustment mechanism to be mounted on the drawer side part without requiring excessive space.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The adjustment device utilizes three-dimensional space efficiently by arranging components in multiple dimensions within the housing. The locking element moves along the longitudinal axis, the adjusting element rotates about an axis, and the spring element provides force in a direction complementary to these movements, maximizing strength while minimizing footprint on the drawer side part.

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