Driving mechanism and driving method for furniture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current furniture systems lack a driving mechanism that combines both push-open and self-closing functions efficiently, requiring separate products for each functionality.
Innovation Solution
A driving mechanism for furniture that includes a first driving device with a locking device and a swing member, which accumulates and releases driving force to move a second furniture part from a retrieve position to an open position, and back, using elastic members and external forces to engage and disengage the locking mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate products are used for push-open and self-closing functions, then each function can be optimized independently, but the overall device complexity and product quantity increase
Solution Approach 1:
The patent combines push-open and self-closing functions into a single driving mechanism. The first elastic member provides push-open force while the second elastic member provides self-closing force, allowing both functions to be integrated in one device rather than requiring separate products.
Solution Approach 2:
The driving mechanism is designed to perform multiple functions: it can push the drawer open, close the drawer automatically, and provide damping during closing. This multi-functional design eliminates the need for separate push-open and self-closing products.
2Ease of operation
If elastic members are used to accumulate driving force, then push-open and self-closing functions are achieved, but the force required to engage the locking mechanism increases
Solution Approach 1:
The swing member in the locking device is designed to pivot dynamically between engaged and disengaged states. During drawer opening, it naturally pivots to disengage from the first driving device while engaging the second driving device, reducing the force needed for transition.
Solution Approach 2:
The locking mechanism operates in periodic cycles: the swing member engages and disengages from different driving devices in sequence during drawer movement. This periodic engagement allows the system to switch between push-open and self-closing modes without requiring high continuous engagement force.
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
Enables seamless transition between open and closed positions of furniture parts, providing both push-open and self-closing functionalities with a single mechanism, enhancing user convenience and operational efficiency.
Implementation Method 1
the first elastic member of the first driving device accumulates a first driving force; and when the swing member is operatively disengaged from the locking part and the guiding member, the first driving force is released to drive the second furniture part to move from a retrieve position to an open position
Implementation Method 2
the second driving device comprises a second base, a second elastic member and a capturing member... the second elastic member of the second driving device releases the second driving force to drive the second furniture part to move toward the retrieve position
Implementation Method 3
the locking device comprises a locking part and a guiding member, the guiding member is configured to generate a force toward the locking part

AI summary
A driving mechanism for furniture is disclosed. The furniture includes a first furniture part and a second furniture part movable relative to the first furniture part. The driving mechanism includes a driving device, a locking device and a swing member. The driving device includes an elastic member. The locking device includes a locking part and a guiding member, the guiding member is for generating a force toward the locking part. The swing member is movably connected to the second furniture part. When the swing member is operatively engaged between the locking part and the guiding member, the elastic member of the driving device accumulates a driving force; and when the swing member is operatively disengaged from the locking part and the guiding member, the driving force is released to drive the second furniture part to move from a retrieve position to an open position relative to the first furniture part.
