With the advancement of transportations and the proliferation of trade barriers among nations, goods from one country can be easily transported and sold to another country. Consumers worldwide benefit the most from this advancement and proliferation as foreign goods are no longer out-of-reach due to either the mere impracticality of shipping as well as exorbitant prices. Despite these developments, international or domestic shipping cost is still an inevitable overhead expense for goods sold in any country.
Shipping cost is determined by both weight and size. To reduce weight, there must be innovative designs that would minimize materials used yet provide proper structural integrity to render a product suitable for its intended use. To reduce volume, parts must be innovatively designed to occupy the smallest footprint possible for ease of packaging and transportation. Designing a product with shipping economy and ease of distribution in mind, the product would have a much higher market penetration power than a similar product not so designed.
The present invention is a rectangular shape flame heater and a pyramid shape flame heater. Both products are rather tall and bulky when fully assembled. The nature of a heater demands strong rigidity and high durability per safety and reliability expectations. For these reasons, traditional flame heaters are made by welding solid metallic parts together. They are therefore very heavy and bulky for shipping, distribution and relocation purposes.
To overcome these shortcomings, the present invention provides a knock-down design of a rectangular shape flame heater and a knock-down design of a pyramid shape flame heater. Before being fully assembled, parts of either heater occupy a space volume many times smaller than the space volume of a fully assembled heater. The pre-assembled compact size is ideal for economy of shipment and ease of distribution.
