Floor Lamp Insertion Rod Snap-Fit Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floor lamps suffer from instability due to a poor fixing manner of the insertion rod, leading to loosening and potential falling off when used for extended periods.
Innovation Solution
A floor lamp device with a grounding device featuring a snap-fit connection between the insertion rod and inner mounting seat, utilizing a sharp end portion, assembling portion with elastic elements, and a fastener for secure assembly, along with an outer decorative lampshade for enhanced stability and ease of assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a floor insertion rod is fixedly connected to a connecting pipe after a top of the floor insertion rod is tightly assembled to the connecting pipe, then the assembly is simple to manufacture, but the stability is poor and the insertion rod loosens and falls off after long use
Solution Approach 1:
The patent applies the dynamics principle by transforming the static tight assembly connection into a dynamic snap-fit connection with elastic portions. The elastic portions can deform during assembly and then recover to maintain a secure connection, providing both ease of assembly and long-term stability. This dynamic characteristic allows the connection to adapt to slight dimensional variations while maintaining reliability.
Solution Approach 2:
The patent segments the connection structure into distinct functional parts: the insertion rod with elastic portions, the inner mounting seat with assembling groove, and the fastener. This segmentation allows each component to perform its specific function - the elastic portions provide flexibility, the groove provides positioning, and the fastener provides securing - thereby achieving both simple assembly and reliable connection.
2Strength
If a snap fit connection is used between the insertion rod and inner mounting seat with elastic portions, then the connection strength is improved, but the device complexity increases
Solution Approach 1:
The patent merges multiple functions into the elastic portions: they serve as both the connection element and the securing mechanism. The elastic portions are integrated directly into the insertion rod structure, eliminating the need for separate fastening components while providing both flexibility and secure attachment. This merging reduces overall device complexity despite the improved connection strength.
Solution Approach 2:
The elastic portions perform self-service by automatically deforming during assembly to engage with the assembling groove and then recovering to maintain the connection. The fastener further simplifies the process by providing a self-contained securing mechanism that requires no additional tools or complex assembly steps. This self-service characteristic maintains simplicity while achieving strong connections.
