Mechanical Spring loaded lid is commonly used in Trash Can. Robustness of mechanical spring is preferred in such products. Sliding mechanism of sofa-set (plate 23B) cum double-bed is preferred in a smaller studio-apartment space. Spring-loaded mechanism is a common feature in ball-point pen (plate 22C). Household stool (plate 22D) with a spring mechanism allows it to reach vertically higher position. Wire Gauge (plate 23E) like hand-tool or pruner uses spring mechanism to convert greater pressure (energy) through spring mechanism.  

Spring is compressed to store energy which is used to convert in to other energy. The stored energy is an import factor in industrial product design and in consumer products. Human body functions as spring during various physical movements. Number industrial tools are dependent on spring mechanism. The spring mechanism (tools) that reduces the human stress great deal and provide comfort.

Animal beings have applied the spring like activities from their birth. It has helped them to physically achieve something for their pleasure or survival. Jumping to catch, jumping to cross a barrier or jumping for pleasure is part of spring paradigm. Muscles, joints and various anatomical functioning coordinate to activate the spring like mechanism (plate 24A-C). Human body has enormous capacity to demonstrate the spring like quality. Each time it takes difficult jumping action it shows various acute angles and gestures that the body can perform.  Figure Skating is one those sports which can demonstrate the most amazing difficult angular gestures and performances. Following are some of the Figure Skating (on ice or on ground) gestures that demonstrate the Spring Paradigm.
