Due to the scarcity of land resources, traditional burials occupy large amounts of land. The state has also emphasized funeral reforms, promoting cremation—where the deceased are directly cremated and placed into urns. Mr. Luo, Sales Manager of HuaHeng Columbarium Factory in Jiangxi, China, noted that many people still choose to bury urns underground, ultimately leading to wasteful land use. A more efficient approach is centralized storage of urns, such as placing them in shelves or cabinets—a Columbarium.
A typical Columbarium adopts a frame-style structure, where each compartment divides the larger space into smaller units, known as Columbarium niches, to store individual urns. Doors can be installed on these compartments, with portraits or glass panels attached. Existing structures are primarily designed for storing ashes, yet people also place significant emotional value on them. For instance, some families prefer both centralized and independent storage for their loved ones' urns. However, many current structures lack sufficient strength, especially since urns are often made from high-density materials that are relatively heavy. This imposes new demands on the structural integrity of the Columbarium framework.
The manufacturing process of columbariums still faces the following shortcomings:
The process is complex, involving numerous welded structures, complicated production steps, and difficulties in assembly. This often results in inadequate strength and precision.
Decorative panels are typically welded in place, making them difficult to replace.
Modular columbariums use a panel-style structure formed by pressing and folding sheets, which simplifies the process and allows easy disassembly. However, several issues persist:
The support panels are composed of interlocked sheets with a hollow middle structure, leading to insufficient strength. To ensure robustness, additional reinforcement structures are required.
The connection and fixation between panels rely solely on flanged edges, making it challenging to achieve consistent shape and strength. Reinforcement ribs are often not securely fixed, complicating the assurance of their positions.
Flanging is required on all four sides of the support panels, significantly increasing both processing time and cost. Additionally, flanging all sides necessitates corner cutting, which is tedious and difficult to execute with high quality.
Patterns on the doors cannot be altered, limiting functional flexibility and opportunities for personalized Columbarium design.
