Solution Overview
Problem
Kitchen cupboards with unfriendly designs that produce loud noises when the pull-out basket is used are inconvenient for users and fail to enhance living comfort.
Innovation Solution
A pull-out basket with sliding rail structures incorporating a hydraulic damper, which includes a cylinder, piston rod, tensile resilient member, and locking mechanism, to reduce noise during extension and retraction, utilizing a tensile spring for reverse pulling force and silencing effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional sliding rail structures are used, then the structure is simple, but loud noises are produced during extension and retraction
Solution Approach 1:
The patent introduces a hydraulic damper as an intermediary component between the sliding rail structures. The damper includes a cylinder with piston rod, tensile resilient member, and locking mechanism that mediates the interaction between the extending/retracting basket and the fixed slot, converting harmful noise into controlled hydraulic damping action while maintaining structural integrity
Solution Approach 2:
The patent applies hydraulic principles by incorporating a hydraulic damper with cylinder and piston rod into the sliding rail structure. The hydraulic system provides controlled resistance during extension and retraction, eliminating noise through fluid damping while managing the complexity through integrated hydraulic components
2Productivity
If the basket is pulled out quickly, then the operation is efficient, but noise is generated
Solution Approach 1:
The hydraulic damper provides velocity-dependent damping force that increases with pulling speed, allowing quick operation while suppressing noise through hydraulic resistance. The fluid-based damping system naturally adapts to different operation speeds, providing silence during both slow and fast movements
Solution Approach 2:
The hydraulic damper serves multiple functions simultaneously: it provides noise elimination, controls extension/retraction speed, and offers buffering action. This multi-functionality allows efficient operation at various speeds without generating noise, as the single component handles both speed control and noise suppression
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 hydraulic damper effectively eliminates noise when the basket is pulled out, enhancing user experience and living comfort by providing a silent operation.
Implementation Method 1
The hydraulic damper comprises a cylinder; an end of the cylinder is connected with a piston rod
Implementation Method 2
a middle section of the fixed slot is mounted with a hydraulic damper; the hydraulic damper achieves silencing and buffering effects when the sliding rail structures extend and retract
Implementation Method 3
a tensile resilient member is mounted below the cylinder; the piston rod and the tensile resilient member is connected with a connection block; the tensile spring provides a reverse pulling force to the hanging hook
