Graduate shows 2015: Taiwan designer Guan-Hao Pan has created a set of condom packages modelled on phallic vegetables, which users can hold to determine the correct girth for their contraceptive sheath (+ slideshow).
Pan's Love Guide Condoms are packed into tubes that are based on different fruit and vegetables, and correspond to the size of the latex sheaths inside.
The five different sizes range from zucchini – the biggest at five centimetres in diameter – down through turnip, banana, carrot, and finally cucumber, measuring three centimetres across.
The designer hopes that by holding the cylinders, users will be able to match one with their penis girth.
In each tube, 12 condoms are individually packaged in containers with lids patterned to look like the sliced fruit and vegetables.
Made from card, the packaging carries simple graphics including the Love Guide logo and a drawing of the food.
Pan – who studied at the National Taipei University of Technology – designed the condoms to prevent users from picking up the incorrect size, as this can have consequences.
"Studies show that more than 60 per cent of users choose a wrong size while shopping for condoms," he said in his project statement. "In addition to discomfort, wrong size selection increases the risk of slippage and rupture."
"A condom becomes much less effective if it is the wrong size, worn on the wrong side, or its tip is not squeezed when worn," Pan added. "It may cause pregnancy and/or sexually-transmitted diseases."
He also identified that condoms are commonly worn inside out, increasing the risk of tearing the latex and of spillages.
To prevent mishaps, he added a flap inside each container that pushes up the teat for easier application.
"Each condom comes in a specially designed case with a rising tip, making it easy to pick the condom from the right side while squeezing the tip at the same time," said Pan, who added that this also aids application in the dark and for the blind.
Earlier this year, a group of UK schoolchildren won an award for a conceptual condom design that would change colour when it comes into contact with a sexually transmitted infection.
Designers have come up with a variety of other ideas for improving contraception, including a condom wrapper that can be opened with a simple finger-clicking action and an open-source, intrauterine device made using a one-cent coin.
A condom applicator designed to help AIDS prevention was named the Most Beautiful Object in South Africa in 2007.
