Hindered-to-flip-up structure for desktop lifting platform, and corresponding desktop lifting platform
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional desktop lifting platforms risk damaging items on the desk and overloading the electric motor during descent, as they may press or crush objects and cause mechanical stress.
Innovation Solution
A hindered-to-flip-up structure for the desktop lifting platform, featuring a supporting plate with a flip plate that rotates upwardly when limited by a limiting device, preventing downward rotation and thus protecting items from crushing and reducing motor overload.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the desktop board descends directly without a flip mechanism, then the structure is simple, but items on the desk may be crushed and the motor may be overloaded
Solution Approach 1:
The patent applies the dynamics principle by transforming the static desktop board into a dynamic flip board that can rotate between horizontal and vertical positions. The flip board is hinged to the support column and can automatically flip upward when encountering resistance during descent, converting a potentially harmful static pressing force into a dynamic avoidance motion that protects both items and the motor
Solution Approach 2:
The patent introduces an intermediary flip mechanism between the motor-driven support column and the desktop board. This flip board acts as a mediator that absorbs the impact when items are present on the desk, preventing direct transmission of crushing force to both the items and the motor, thereby resolving the contradiction between simplicity and protection
2Reliability
If the desktop board presses down on items during descent, then the lifting function is achieved, but the motor may be overloaded and damaged
Solution Approach 1:
The patent applies preliminary anti-action by pre-configuring the flip board with a downward pressing force mechanism. Before the motor-driven descent begins, the flip board is positioned to exert a preliminary downward force, creating a pre-compressed state that prevents sudden motor overload when encountering items during the descent process
Solution Approach 2:
The dynamic flip mechanism allows the board to automatically adjust during operation. When resistance is detected during descent (indicating items are present), the flip board rotates upward, dynamically changing the operation mode from direct pressing to flipped avoidance, thereby protecting the motor while maintaining operational simplicity
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 structure effectively prevents items from being crushed and protects the lifting platform by allowing the flip plate to flip upward when encountering objects, ensuring safe operation and reducing the risk of motor overload.
Implementation Method 1
the flip plate rotates upwardly when limited by a limiting device
Implementation Method 2
the flip plate is in rotatable connection with the fixing plate while downward rotation of the flip plate is limited by a limiting device

AI summary
Disclosed is a hindered-to-flip-up structure for a desktop lifting platform, wherein the desktop lifting platform includes a lifting column, and a supporting plate that rises or descends with the lifting column; the hindered-to-flip-up structure is disposed on the supporting plate; the supporting plate includes a fixing plate and a flip plate in rotatable connection with the fixing plate; a limiting device is provided on the supporting plate; when the flip plate rotates downwardly, the limiting device limits the flip plate from downward rotation; the flip plate is free to rotate upwardly. Further disclosed is a desktop lifting platform adopting the hindered-to-flip-up structure. The disclosures offer advantages of better protecting the desktop lifting platform and protecting items on the desk from being excessively crushed and crashed. The disclosures are mainly placed on a work platform such as a desk.
