Mother and baby bags often need to carry a large number of items such as milk bottles, diapers, and clothes, which are heavy. If the traditional carrying system is not designed properly, mothers carrying it for a long time may easily cause shoulder and neck pain and waist strain. Optimizing the carrying system based on ergonomics can reasonably disperse the weight of the bag according to the structure and movement of the human body, reduce pressure concentration, improve carrying comfort, and reduce the risk of physical injury. This is not only related to the use experience of mothers, but also crucial to their physical health. Therefore, it is of urgent practical significance to optimize the ergonomics and improve the comfort of the mother and baby bag carrying system.
The shoulder strap is a key component that directly contacts the shoulder, and its design determines the stress on the shoulder. The wide shoulder strap design can increase the shoulder stress area and reduce the pressure per unit area. For example, increasing the shoulder strap width from the conventional 3 cm to 5-6 cm can effectively relieve the pain of shoulder constriction. At the same time, the shoulder strap should have good curvature and elasticity, fit the shoulder curve, and reduce friction. Add breathable pressure relief sponge to the inner side of the shoulder strap to enhance breathability and further disperse pressure. In addition, the shoulder strap buckle with adjustable length is designed to meet the needs of mothers of different heights, ensuring that the shoulder strap is always in the right position to avoid slipping or being too tight.
The waist belt can effectively transfer weight to the waist in the mother and baby bag carrying system, reducing the burden on the shoulders. The optimized waist belt should be thickened and widened to increase the contact area with the waist. For example, a waist belt with a width of 15-20 cm and high-density foam filling can provide comfortable support. The waist belt must have flexible adjustment functions and can be accurately adjusted according to the waist circumference of the mother to ensure a close fit to the waist. At the same time, the angle and position of the waist belt should be reasonably set to match the natural waist curve of the human body, evenly distribute part of the weight to the pelvis, make the waist the main load-bearing part, and improve the overall stability and comfort of the carrying.
A good back support system is an important guarantee for the comfort of the mother and baby bag. The back of the bag is cut three-dimensionally to fit the curve of the back of the human body, reduce the gap, and avoid the bag shaking when carrying. Built-in hard support plates or elastic support strips enhance the support of the back and prevent the bag from deforming and oppressing the back. At the same time, the back is filled with breathable mesh and soft cushioning materials to form an air circulation channel to accelerate heat dissipation and keep the back dry. For example, the use of honeycomb breathable materials not only ensures support but also improves breathability, and it is not easy to feel stuffy when carrying for a long time.
In addition to structural optimization, reducing the weight of the carrying system itself can also improve comfort. Lightweight and high-strength materials are used to make shoulder straps, waist belts and back support components, such as high-strength nylon fibers instead of traditional cotton materials, which can reduce weight while ensuring durability. Simplify the structural design of the carrying system, remove unnecessary decorations and accessories, and reduce redundant weight. In addition, through the reasonable internal structure design of the bag, the placement of items is optimized to make the weight distribution more even, avoid the extra burden caused by the center of gravity shift, and achieve overall load reduction.
To adapt to different usage scenarios of mothers, the mother and baby bag carrying system should be flexible and multifunctional. Design a detachable and convertible carrying method, such as shoulder, crossbody, hand-held and other modes to switch freely. Add an adjustable chest strap, connect the shoulder straps on both sides, adjust the distance between the shoulder straps to prevent the shoulder straps from slipping, and enhance the stability of the carrying in special circumstances, such as going up and down stairs and running. In addition, set multiple buckles and storage pockets on the carrying system to facilitate the hanging of small objects such as baby stroller hooks and keys, and improve the convenience and comfort of use.
It is crucial to conduct ergonomic testing and user feedback collection on the optimized mother and baby bag carrying system. Invite mothers of different body shapes and ages to conduct actual carrying experience tests, simulate daily travel, shopping and other scenarios, and record the carrying time, pressure perception of various parts of the body and comfort evaluation. Use pressure sensors and other equipment to collect pressure distribution data on shoulders, waist, back and other parts, and analyze pressure concentration points and unreasonable designs. Based on the test results and user feedback, targeted improvements are made to the carrying system, and the design is continuously improved to ensure that the optimized carrying system achieves the best results in terms of ergonomics and comfort.
