Drawer Hooking Assembly With Integrated Longitudinal Adjustment
Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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.
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.
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
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.
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
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.
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 enables precise and versatile adjustment of the drawer's position, ensuring correct alignment and operation of self-closing and push-type systems, enhancing aesthetic results and reducing complexity and costs by integrating adjustment capabilities within the hooking device.
