Tealight Holder Bottom Grooves for Paraffin Drainage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing table tealight holders experience substantial loss of unused liquid paraffin due to inefficient drainage, leading to wastage in large-scale production.
Innovation Solution
A table cup-shaped tealight holder with a groove-shaped forming along the bottom edge and a central conical recess, where the grooves connect to the recess at specific angles to facilitate the flow of liquid paraffin during the final burning phase, allowing for its more extensive utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If a groove-shaped forming is provided along the bottom edge to drain liquid paraffin, then liquid paraffin can be drained to the groove, but a substantial amount of liquid paraffin remains unused at the bottom centre
Solution Approach 1:
The bottom structure is segmented into multiple functional zones: a central recess for collecting liquid paraffin, radial grooves for drainage pathways, and an outer groove-shaped forming for final collection. This segmentation allows liquid paraffin to be systematically directed through different zones, ensuring complete utilization while maintaining a relatively simple overall structure.
Solution Approach 2:
The invention introduces a vertical dimension by creating a recess in the bottom centre that extends downward. This vertical space allows liquid paraffin to be collected and stored in a three-dimensional manner rather than merely flowing along the two-dimensional bottom surface, thereby increasing the effective capacity for liquid paraffin utilization.
2Productivity
If the bottom is made convex towards the inner part to drain liquid paraffin to the groove, then liquid paraffin flows to the groove, but part of the liquid paraffin remains not used
Solution Approach 1:
The grooves are pre-configured to extend from the outer groove-shaped forming toward the central recess, creating predetermined drainage pathways. This preliminary arrangement ensures that liquid paraffin is automatically directed toward the center and collected in the recess, maximizing utilization before the tealight holder is removed from the flame.
Solution Approach 2:
The invention optimizes the angle parameters of the grooves and the depth of the recess to control liquid paraffin flow characteristics. By adjusting these geometric parameters, the system ensures that liquid paraffin flows efficiently into the recess without remaining stagnant in the grooves, thereby maximizing utilization efficiency.
