Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a frame structure with folding storage is used to reduce packaging volume, then the volume for packaging and transportation is reduced, but the processing accuracy requirement and assembly difficulty increase due to hole alignment requirements
Solution Approach 1:
The patent extracts the fastening function from screw-based connections and implements it through elastic clamping strips that directly clamp the supporting rod. This eliminates the need for through holes and screw holes in the upper and center tubes, thereby resolving the hole alignment precision problem while maintaining the folding frame structure for compact packaging
Solution Approach 2:
The patent introduces elastic clamping strips as an intermediary component between the frame structure and the supporting rod. These clamping strips provide the fastening function without requiring precise hole alignment, serving as a mediator that connects the folding frame to the supporting rod through a tolerance-friendly mechanism
2Reliability
If screws are used to fix the decorated tree trunk, then the trunk can be secured, but the assembly becomes more difficult and the fixation reliability decreases due to potential screw stripping or loosening
Solution Approach 1:
The patent replaces the screw-based mechanical fastening system with an elastic clamping mechanism. The elastic clamping strips use elastic deformation and friction force to secure the supporting rod, eliminating screws entirely. This substitution improves reliability by avoiding screw stripping and loosening issues while simplifying the assembly process
Solution Approach 2:
The elastic clamping strips automatically adjust to the supporting rod through elastic deformation, providing self-adjusting clamping force. The elasticity of the strips allows them to accommodate minor dimensional variations and maintain reliable fixation without requiring precise manual adjustment, making the assembly process easier and more reliable
3Reliability
If through holes are formed in the upper tube and center tube for screw fixation, then the decorated tree can be fixed, but the processing complexity and assembly difficulty increase
Solution Approach 1:
The patent extracts the fixation function from the tube structure itself (which would require through holes) and relocates it to separate elastic clamping strips. This separation eliminates the need for through holes in the upper and center tubes, simplifying the tube structure while maintaining reliable fixation through the clamping mechanism

Function Achieved in This Case
The solution provides a simple and efficient installation method, increased stability, and reduced processing costs by eliminating the need for precise screw alignment, while ensuring secure locking and easy folding and expansion of the bracket.
Implementation Method 1
a pressing spring, wherein the pressing spring is arranged on an upper end of the locking pin, and downward pressure is provided by the pressing spring to the locking pin
Implementation Method 2
a plurality of elastic clamping strips are formed on a lower hole edge of the inserting through hole, and an upper end of each elastic clamping strip is connected with the lower hole edge of the inserting through hole by a single point, so as to make the elastic clamping strips have a certain deformation property

AI summary
The present invention discloses a decorated tree bracket base. A locking seat is installed on an upper sleeve, the locking seat has a sleeve structure, and an inserting through hole which is the same as a center hole of the supporting tube shaft is formed in the locking seat; a plurality of elastic clamping strips are formed on the lower hole edge of the inserting through hole, and the upper end of each elastic clamping strip is connected with the lower hole edge of the inserting through hole by a single point. An elastic clamping structure can not only realize the effect of fixing the trunk of the decorated tree, but also provide a simpler and more efficient installation method and a low installation difficulty, which is more in line with the current market demand.
