Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fan lamps with folding blades face pollution issues due to lubricating oil being thrown out by centrifugal force during blade retraction, as existing mechanisms lack effective containment.
Innovation Solution
A fan lamp design featuring a turntable, elastic restoring assembly, and fan blades connected through an upper and lower cover with a central spindle, forming a closed accommodating space to house the elastic member, reducing the likelihood of lubricating oil ejection during blade extension and retraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fan blades are made into a folding type with elastic retraction mechanism, then the blowing function can be provided seasonally, but lubricating oil is thrown out by centrifugal force causing pollution
Solution Approach 1:
The patent utilizes the centrifugal force that was causing harm (throwing out lubricating oil) as a beneficial force to drive the fan blade unfolding mechanism. The centrifugal force generated during motor rotation automatically pushes the fan blades from the folded state to the unfolded state, eliminating the need for separate unfolding mechanisms and preventing lubricating oil leakage.
Solution Approach 2:
The patent employs a flexible connecting structure between the fan blade and the rotating assembly that allows the blade to transition between folded and unfolded states. This flexible connection design enables the blade to retract elastically when the motor stops while maintaining structural integrity and preventing lubricating oil from being ejected during operation.
2Productivity
If fan blades are unfolded by centrifugal force during rotation, then the blowing function is activated, but lubricating oil is ejected causing environmental pollution
Solution Approach 1:
The patent converts the harmful centrifugal force into a beneficial driving mechanism for blade deployment. The centrifugal force generated during rotation is used to automatically unfold the fan blades from their folded storage position to the operational position, while the blade design and connection structure prevent lubricating oil from being ejected during this process.
3Ease of operation
If fan blades retract elastically upon switching off, then the folding mechanism works automatically, but the lubricating oil mechanism causes pollution
Solution Approach 1:
The patent implements a self-service mechanism where the fan blades automatically retract to their folded position using elastic restoring force when the motor stops rotating. This eliminates the need for separate retraction mechanisms, reduces structural complexity, and prevents lubricating oil from being exposed to centrifugal forces that would cause pollution.
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 design effectively contains lubricating oil within the closed space, minimizing pollution and ensuring smooth operation of the fan blades while maintaining their folding functionality.
Implementation Method 1
an elastic member, two ends of the elastic member are connected with the upper cover and the lower cover respectively, the upper cover can rotate relative to the lower cover and drives the elastic member to be deformed elastically
Implementation Method 2
Upon the fan being switched on, the fan blades are unfolded by a centrifugal force generated by the rotation of a central spindle of the fan
