THE SOLUTION PROVIDED BY LF TECHNOLOGIES

Industrial Design

Human-Machine Interface

Mechanical Design

In view of the qualification and evolution of their product, our client, a French manufacturer of sporting goods, was looking for a complete solution for testing and rating their products, allowing a classification according to simple and easily understandable criteria.

Main functions

Objective

Find a technical solution that avoids the need for a full-scale test (floating bipalm robot “swimming” in a pool, etc.), while guaranteeing accurate measurements and high reproducibility of the tests.

Problematic Issues

How to design test equipment to qualify fins on efficiency and acceleration criteria with an ergonomic system and a simple and quick implementation

Solution and Result

LF Technologies has designed a small volume pool where only one leg is represented. The pool is oblong in shape and does not exceed 4 metres in length and 1.5 metres in width. Its shape allows water to circulate with little effort.

Two keels equipped with trolleys simulate a human leg. By varying the position of the trolleys, it is possible to simulate several leg sizes.

The water circulation is done thanks to propellers to simulate the diver’s speed of advance in the water.

LF Technologies has proposed a system to qualify the fin alone and to measure its performance in different finning configurations.

The measurements carried out make it possible to characterise and classify the fins tested according to objective criteria of thrust force, swimming power and efficiency.
