Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional camping lights with integrated power supply and wire designs are bulky, inconvenient to carry, and have fixed wire lengths, limiting their application range and incurring high repair costs when the wire is damaged.
Innovation Solution
A simple and portable camping light design featuring a winding reel with oppositely arranged first and second wire winding disks, a winding disk clamp, and a wire tightening shaft, allowing for separable components and adjustable wire length, along with a detachable winding reel structure for enhanced flexibility and convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If an integrated design on power supply and wire is used, then the structure is simple, but the volume is large and portability is poor
Solution Approach 1:
The camping light is divided into separate modules: a power supply unit and a lighting unit connected by an extendable wire. The power supply can be detached from the lighting components, allowing the main body to be compact while the wire can be extended when needed. This segmentation resolves the contradiction by enabling small storage volume while maintaining functional simplicity through modular design.
Solution Approach 2:
The wire connecting the power supply to the lighting unit is designed to be extendable and retractable rather than fixed. This dynamic wire length adjustment allows the camping light to have a compact form when stored (wire retracted) while providing sufficient reach when in use (wire extended), thus resolving the volume-portability contradiction.
2Device complexity
If an integrated design on power supply and wire is used, then the structure is simple, but portability and flexibility are poor
Solution Approach 1:
By separating the power supply from the lighting unit with a detachable connection, the design allows users to carry only the essential components and attach the power supply when needed. This modular segmentation improves portability while maintaining operational simplicity through standardized connection interfaces.
Solution Approach 2:
The extendable and retractable wire provides dynamic flexibility, allowing the camping light to adapt between a compact portable state and an extended operational state. This dynamic design directly addresses the portability and flexibility requirements while keeping the overall structure simple.
3Device complexity
If the wire length is fixed, then the structure is simple, but the application range is limited
Solution Approach 1:
The wire is designed with extendable and retractable capabilities, transforming from a fixed-length component to a dynamically adjustable one. This allows the camping light to adapt to various application scenarios by adjusting the wire length, thereby expanding the application range while maintaining structural simplicity through the use of a telescopic mechanism.
4Device complexity
If the wire is damaged, then the repair cost is high, but the integrated design prevents modular replacement
Solution Approach 1:
By segmenting the camping light into replaceable modules with detachable connections, the design allows the power supply or wire to be independently replaced if damaged. This modular segmentation enables cost-effective repairs by replacing only the damaged component rather than the entire integrated unit, directly addressing the repair cost issue.
Solution Approach 2:
The detachable design allows damaged components like the wire to be easily removed and replaced with new ones, while the main power supply unit can be retained and reused. This approach reduces repair costs by enabling selective replacement of only the damaged parts rather than discarding the entire system.

AI summary
A simple and portable camping light is provided, which aims to provide a simple and portable camping light that is simple in structure and convenient to assemble and disassemble. A key point of the technical solution is that a rotary plate matched with a second wire winding disk is arranged at a bottom end of a winding reel; the second wire winding disk is rotatably connected to a first wire winding disk; and the winding reel can be of an integrally formed structure and is fixedly connected to the first wire winding disk; or the winding reel can be of a detachable structure and includes an upper reel body and a lower reel body. The camping light is simple in structure, and a light string can be orderly collected. Different structural designs of the winding reel meet a variety of usage needs, and the components are connected stably.
