TECHNICAL FIELD
[0001] The present application relates to a learning aid, in particular a learning aid for assisting posture correction for pupils in the body development period, and more particularly to a conscious incentive type sitting posture corrector and a method of use. BACKGROUND
[0002] At present, in today's society, whether it is a child with heavy schoolwork or an office worker who needs to work at a desk for a long time, long-term sitting has become a normal part of life. However, long periods of sitting can easily lead to the formation of an incorrect sitting posture. In particular, for children whose bodies are still in the development stage, when they are engaged in activities such as homework or reading, their bodies will involuntarily bend forward, resulting in problems such as a hunched back, a forward-stretched head and neck, and the like. This incorrect sitting posture not only affects personal appearance, leading to a hunched back and a low head and neck when walking in adulthood, but also poses a serious threat to health, being the culprit of a series of health problems such as myopia, cervical spondylosis, and scoliosis, and can cause lifelong physical defects.
[0003] In order to solve this problem, a variety of sitting posture correction products have appeared on the market. For example, functional correction desks and chairs can regulate the sitting posture to some extent, but cannot effectively prevent the user from bending the upper body forward and lying on the desk. Another common solution is to install a chest baffle on the desk, with the intention of preventing the body from being too close to the desktop. However, this design often backfires, as the user, especially children, will involuntarily lean their center of gravity on the upper part of the baffle, especially the neck and head, resulting in more severe forward bending and stretching of the neck and head.
[0004] In addition, there are also some mandatory physical correction devices, such as restraints worn on the back and neck, and posture sensing alarms. These devices use external force to restrain or sound / vibration alarms to remind the user. Although they have some effect, their disadvantages are also very obvious: first, physical restraint greatly limits the user's body freedom, forcing them to be in a fixed posture for a long time, which is very easy to cause fatigue and muscle stiffness; second, this kind of mandatory intervention can cause strong discomfort and a sense of being restrained in the user, easily leading to aversion and resistance, resulting in their unwillingness to wear it for a long time, and ultimately failing to correct the posture.
[0005] The shortcomings of the above prior art make it a difficult problem for many parents and office workers to effectively correct an incorrect sitting posture in a comfortable, non-mandatory and willingly accepted manner. SUMMARY
