Solution Overview

Problem

Existing hooking devices for connecting drawers to longitudinal guides lack the ability to adjust the front portion of the drawer in the longitudinal direction, leading to potential aesthetic issues with self-closing and push-type drawer systems, requiring separate adjustment devices that increase complexity and cost.

Innovation Solution

A hooking device with a support body that can be fixed to the drawer, featuring an oscillating command lever and adjustable parts that allow for longitudinal, height, and lateral adjustments, including a wedge-shaped element and manual gripping elements, to precisely position the drawer relative to the guide without additional adjustment devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If separate regulating devices are provided for longitudinal adjustment of the drawer front, then the drawer position can be precisely adjusted, but the constructive complexity and cost increase

Engineering Contradiction:
Improvedrawer front position precisionVSAvoidconstruction complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent combines the longitudinal adjustment function with the existing hooking device by making the support body adjustable in the longitudinal direction. The support body is divided into a fixed part and a movable part that can slide relative to each other, allowing longitudinal position adjustment without requiring separate regulating devices. This merging of functions reduces overall device complexity while maintaining precise adjustment capability.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The support body is designed to perform multiple functions: it provides lateral adjustment, height adjustment, and now longitudinal adjustment. By making the support body itself adjustable in the longitudinal direction through the sliding mechanism between fixed and movable parts, the device achieves multi-functionality without adding separate adjustment mechanisms, thereby reducing complexity.

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

2Ease of manufacture

If the longitudinal guides are fixed with non precise positioning, then the installation is easier, but the aesthetic result deteriorates due to improper drawer front positioning

Engineering Contradiction:
Improveinstallation easeVSAvoiddrawer front position precision
Core Design Contradiction:
Ease of manufactureVSManufacturing precision

Solution Approach 1:

The support body incorporates a dynamic adjustment mechanism where the movable part can slide along the longitudinal direction relative to the fixed part. This allows the drawer front position to be dynamically adjusted after installation, enabling precise positioning without requiring extremely precise initial fixing of the longitudinal guides, thus maintaining both installation ease and aesthetic precision.

Inventive Principle:
Principle #15Dynamics

3Device complexity

If the drawer front position is not precisely controlled, then the adjustment mechanism is simpler, but the operation of self-closing and push-type systems deteriorates

Engineering Contradiction:
Improveadjustment mechanism complexityVSAvoidsystem operation reliability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The movable part of the support body enables dynamic positioning of the drawer front along the longitudinal direction, ensuring that the drawer front stops at the correct position for proper operation of self-closing and push-type systems. This dynamic adjustment capability maintains system reliability without requiring overly complex adjustment mechanisms.

Inventive Principle:
Principle #15Dynamics
