Size design analysis of Portable PVC Baseball
The size design of portable PVC baseball needs to balance functionality (easy to carry and operate) and practicality (meeting the requirements of usage scenarios). The following are the key design dimensions and specific suggestions:
Core size range
Diameter design
Mainstream size: 6.0 cm to 7.0 cm (7.2-7.3 cm smaller than standard baseball).
Portability: The 6.0 cm diameter sphere has a volume of approximately 60% of a standard sphere and can be easily placed in the side pocket or pocket of a backpack.
Maneuverability: The 7.0-centimeter diameter sphere is closer to the standard ball grip, making it suitable for the transition from portability to training.
Limit size: The diameter of some portable models can be compressed to 5.5 centimeters (such as fidget spinner toy balls), but the authenticity of the hitting feedback must be sacrificed.
Weight optimization
Lightweight target: Usually controlled within 50 to 100 grams (a standard ball weighs approximately 140 to 150 grams).
Children’s version: 50-70 grams, reducing the difficulty of hitting and enhancing safety.
Adult version: 80-100 grams, balancing portability and a good hitting feel.
2. Adaptation of size to usage scenarios
Travel/Outdoor scene:
Size selection: Diameter 6.0-6.5 cm, weight 50-70 grams.
Design logic: The miniaturized design is convenient to carry while retaining the basic hitting function, making it suitable for entertainment during short trips or camping.
Desktop/indoor scene:
Size selection: Diameter 6.5-7.0 cm, weight 80-100 grams.
Design logic: By controlling the flight distance (such as reducing weight) to minimize space occupation, while maintaining a certain impact feedback, it is suitable for office or home tabletop games.
Children’s enlightenment scene:
Size selection: Diameter 6.0-6.5 cm, weight 50-70 grams.
Design logic: Lightweight design reduces the risk of accidental hits, large-sized balls enhance grip stability, and help children quickly master hitting skills.
3. Collaborative design of materials and structures
PVC material selection:
Foamed PVC: By using microcellular foaming technology to reduce density and achieve weight reduction (for example, the density can be reduced to 0.8-1.0 grams per cubic centimeter), while maintaining the elasticity of the sphere.
Composite structure: It adopts a composite structure with an inner core (such as cork) and a PVC outer shell, which not only ensures durability but also reduces the overall weight.
Surface treatment:
Anti-slip texture: The surface is coated with a concave-convex texture or silicone coating to enhance grip stability and reduce the risk of dropping.
Wear-resistant coating: Made of high-hardness PVC material or surface hardening treatment, it enhances the ball’s wear resistance and extends its service life.
4. User demand-driven design optimization
Security Enhancement
Edge rounded corner treatment: Avoid sharp edges and corners to reduce the risk of injury when accidentally hitting the body.
Soft inner core: Made of low-density PVC or foamed materials to reduce impact force.
Enhancement of fun
Replaceable casing: Through modular design, users are allowed to replace the casing in different colors or patterns, enhancing the product’s appeal.
Lighting/sound function: Built-in LED lights or miniature bells to enhance the fun of night or indoor activities.
5. Reference to actual cases
Children’s portable version:
With a diameter of 6.2 centimeters and a weight of 65 grams, the surface is decorated with cartoon patterns and has a bell inside. It is suitable for children aged 3 to 8.
Adult travel fee:
With a diameter of 6.8 centimeters and a weight of 90 grams, it features an anti-slip texture design on the surface, making it suitable for outdoor travel or picnics.
