Candleholder with Nesting Envelope and Centering Projection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Candle holders designed for disk-shaped candles, particularly tea lights, appear unattractive when not in use and lack aesthetic appeal, limiting their decorative potential, especially when used in large numbers.
Innovation Solution
A candle holder design featuring a receiving body with a centering extension and an enveloping body that forms a seamless, aesthetically customizable exterior, allowing for stackability and creative arrangements, with options for additional elements like ballast or fragrance inserts, and materials like sheet metal and plastic for enhanced appearance and manufacturability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If an enveloping body is added to cover the receiving body, then aesthetic appearance is improved, but device complexity increases
Solution Approach 1:
The enveloping body is nested over the receiving body, with the enveloping body forming an outer shell that covers the inner receiving body. This nesting approach allows the aesthetic envelope to protect and enhance the functional receiving body without requiring separate mounting structures, thereby improving appearance while minimizing added complexity.
2Area of stationary object
If candle holders are arranged in stacked groups, then space utilization is improved, but aesthetic appearance deteriorates due to visible gaps and irregular arrangements
Solution Approach 1:
The centering extension protrudes asymmetrically beyond the enveloping body, creating a distinctive stacking interface. This asymmetric design element allows multiple candle holders to stack neatly in columns while the protruding extension provides visual interest and prevents单调 repetition, thereby maintaining aesthetic appeal in stacked arrangements.
Solution Approach 2:
The enveloping body features a convex cross-sectional profile that complements the concave profile of the stack base, creating smooth curved surfaces for stacking. These curved geometries allow candle holders to nest together seamlessly in stacked arrangements, eliminating gaps and creating an aesthetically pleasing columnar appearance while maximizing space utilization.
3Shape
If the enveloping body is made from sheet metal, then aesthetic quality is improved, but manufacturing complexity increases
Solution Approach 1:
The enveloping body is formed from a sheet metal blank that is shaped into a thin-walled envelope structure. This thin-film approach allows the sheet metal to be formed into complex curved surfaces and aesthetic profiles while minimizing material usage and simplifying the manufacturing process through standard sheet metal forming techniques.

AI summary
The invention relates to a candleholder (20) for receiving disk-shaped candles, in particular tea candles, having a receiving body (21) and an envelope body (22), which is implemented independently of the receiving body, and which is implemented as an annular sleeve having a substantially L-shaped or U-shaped cross-section, having an envelope shell (40), which covers a peripheral surface (39) of the receiving body, an annular envelope disc, which covers the top side of the receiving body, and an envelope border, which borders an inner margin of a receiving opening of the receiving body, wherein the bottom side of said receiving body is provided with a centering projection, which protrudes from an annular stacking base of said receiving body, and the outer centering diameter thereof corresponding to an inner centering diameter of said envelope border, and wherein said envelope disc of said envelope body has a cross-sectional profile which corresponds to a cross-sectional profile of said stacking base.
