Flame-shaped chip assembly inversion for flameless candle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic flameless candles have a large opening in their housing, exposing the internal structure and affecting the appearance and protection of the internal components during assembly and use.
Innovation Solution
A flame-shaped chip design featuring an upper flame-shaped piece, an umbrella, and a needle, where the needle serves as the umbrella rod, allowing for independent placement and easy assembly/disassembly, and the umbrella covers the internal structure for aesthetic and protective purposes, with the needle acting as a fulcrum for swinging the flame-shaped piece.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the flame-shaped chip is fixed inside the candle and the candle-shaped housing is wrapped through the flame-shaped chip through the central opening, then the assembly is completed, but the opening in housing becomes large and the internal structure is exposed
Solution Approach 1:
Instead of inserting the flame-shaped chip through the bottom opening of the housing, the patent inverts the assembly sequence by inserting the chip through the top opening. The needle component passes through the top of the housing first, then the umbrella and flame-shaped piece are assembled in reverse order, allowing the housing to completely enclose the internal structure without large exposed openings.
Solution Approach 2:
The patent employs nested structure where the flame-shaped piece is positioned within the umbrella, and both are contained within the housing. The needle serves as a central axis through which all components are nested, creating a compact arrangement that fits within the housing without requiring large openings.
2Ease of operation
If the opening in housing is large to accommodate the flame-shaped chip, then assembly is possible, but the internal structure can be seen from the opening affecting overall appearance
Solution Approach 1:
The patent reverses the traditional assembly approach by inserting components from the top rather than through a large bottom opening. This inversion allows the housing to be closed completely, hiding the internal structure while maintaining assembly feasibility through the top opening that can be smaller and less obtrusive.
3Productivity
If the flame-shaped chip is assembled through the central opening of the housing, then the assembly is completed, but there is no protection for the internal structure
Solution Approach 1:
The patent creates a nested arrangement where the flame-shaped piece is positioned within the umbrella structure, and both are contained within the housing. This nested configuration protects the internal components while maintaining a compact assembly process that does not compromise assembly efficiency.
Solution Approach 2:
By inverting the assembly sequence to insert from the top, the housing can be closed to enclose and protect the internal structure, whereas traditional bottom-insertion methods leave the structure exposed or require large openings that compromise protection.
