Description

Technical Field

[0001] The invention relates to the technical field of jewelry design, and in particular to a template ruler for designing a multifunctional jewelry necklace. Background Art

[0002] In the field of jewelry design, especially when designing high-end jewelry necklaces, designers often face the challenge of quickly and accurately drawing necklaces of various shapes and sizes. Drawing a necklace first requires determining the center point of the inner circle of the collar, which then determines the shape and design area of ​​the necklace.

[0003] Jewelry design drawings typically use A4 paper, so it's necessary to determine the vertical centerline of the A4 paper. Based on the dimensions of the main design area of ​​the necklace, the intersection of the horizontal centerpoint and the vertical centerline is located, serving as the center point for the necklace's inner ring design. After determining the center point, the designer uses a compass to draw the necklace's inner ring, typically requiring accurate calculation of its dimensions before completing the drawing with the compass. After completing the inner ring, the designer needs to determine the shape of the necklace's outer ring, a process often aided by a universal curved ruler. However, since the curves of universal curved rulers may not always be perfectly suitable for necklace designs, designers often rely on their experience and hand-drawing skills to repeatedly adjust the curves to ensure a smooth flow. This process typically takes 5 to 10 minutes, but often presents issues such as unsmooth lines, tilting, pinholes left by the compass, stains from wiping auxiliary lines, and blurred images.

[0004] Furthermore, high-end jewelry necklace designs often use large gemstones as the main stones. When drawing gemstones and accent stones, designers often use template rulers of universal shapes, including the TIMELT-777-1 and TIMELT-777-2, which range in size from approximately 3mm to 18mm. However, these sizes cannot meet the gemstone size requirements commonly used in high-end jewelry necklace design, especially large gemstones between 25mm and 35mm. Furthermore, radial design methods are often used to arrange design elements in high-end jewelry necklace design, requiring designers to use protractors to draw marking lines at different angles. This process requires carrying multiple template rulers or compasses with different functions, which is not only inconvenient to carry, but also relatively cumbersome at each step.
