USB Split Head Lamp With Backup Power for Battery Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing split head lamps lack interchangeability in their power supply systems, leading to difficulties in replacing batteries and potential darkness during replacement, as they are often exclusively designed for specific structures, and users may be left without lighting.
Innovation Solution
A split head lamp with a built-in energy storage element, incorporating a head lamp body, connecting line, and external power source, featuring a USB interface, MCU chip, and gear switch for power control, allowing compatibility with various power sources and ensuring continuous lighting during battery replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a battery and interface are exclusively designed for a specific structure, then the power supply system can be integrated well, but the interchangeability is poor
Solution Approach 1:
The patent applies universality by designing a standardized USB interface that can connect to various external power sources (power banks, mobile phones, computers, wall adapters). This allows the headlamp to work with multiple different power sources while maintaining a stable integrated structure through the universal USB connection standard.
2Ease of repair
If the battery is replaced in a traditionally designed head lamp, then the power supply can be renewed, but the user will be trapped in darkness without lighting during replacement
Solution Approach 1:
The patent applies preliminary action by providing an energy storage element (built-in battery) that is pre-charged and ready to immediately take over power supply when the external power source is disconnected or being replaced. This ensures continuous lighting without interruption during battery replacement operations.
3Adaptability or versatility
If the head lamp uses a built-in energy storage element with USB interface, then the interchangeability of power supply is improved, but the device complexity increases
Solution Approach 1:
The patent applies self-service by implementing automatic power source switching controlled by an MCU chip that detects the presence and status of external power sources. The system automatically manages power intake from external sources, charging the built-in battery, and switching between power sources without requiring manual user intervention, thereby reducing operational complexity despite increased structural complexity.

AI summary
The present application relates to a split head lamp of a built-in energy storage element. The split head lamp includes a head lamp body, a connecting line and an external power source. The head lamp body includes a light-emitting assembly, a circuit board, an energy storage element, and a Micro Control Unit (MCU) chip; the MCU chip is mounted on the circuit board; the circuit board is provided with an energized interface for plugging in the connecting line; power supply of the energy storage element and the external power source is regulated by a program stored in the MCU chip; and the energized interface is a Universal Serial Bus (USB) interface, a power supply system has better interchangeability; and through the present application, lighting may also be continuously temporarily provided when the external power source is replaced or is low, such that the split head lamp is more user-friendly.
