Innovation Solution
A retractable device comprising a retractable main component, holding component, and auxiliary component with clamping edges, buckles, and a handle, allowing for stable and efficient winding and unwinding of decorative light strings, with a storage compartment to keep accessories secure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If simple plastic spool winding is used to package decorative light strings, then the decorative light strings can be stored on spools, but the winding operation is time-consuming and laborious, and the simple plastic spool has no structure to pre-fix the decorative light string causing displacement or loosening during winding
Solution Approach 1:
The retractable auxiliary component pre-fixes one end of the decorative light string before winding begins. This preliminary fixation eliminates the need for manual adjustment during winding, prevents displacement and loosening, and enables automatic winding through rotation of the retractable main component, significantly reducing winding time and labor.
Solution Approach 2:
The retractable device enables automatic winding through the rotation of the retractable main component, which automatically winds the decorative light string without requiring manual repeated winding operations. The system serves itself by converting rotational motion into automatic winding action, reducing both time and labor requirements.
2Stability of the object's composition
If simple plastic spool winding is used, then storage is possible, but the winding is not tight causing the decorative light string to be easy to displace or loosen
Solution Approach 1:
The retractable auxiliary component performs preliminary fixation of one end of the decorative light string before winding begins. This pre-fixing ensures the light string remains stationary and tight during the winding process, preventing displacement and loosening, and achieving stable, tight winding results.
Solution Approach 2:
The retractable auxiliary component provides localized fixation at the end of the decorative light string, creating a stable anchor point that ensures tight winding throughout the entire length of the light string. This local fixation point prevents overall displacement during winding.
3Ease of manufacture
If bundling and binding packaging method is used, then operation is simple, but the decorative light strings get entangled with each other and wires knotting occurs during untie process
Solution Approach 1:
The retractable device enables automatic unwinding through rotation of the retractable main component, which automatically unwinds the decorative light string without requiring manual untangling. The system serves itself by converting rotational motion into automatic unwinding action, eliminating entanglement and knotting issues while maintaining simple packaging operation.
