Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing split type headlamps face challenges in ensuring energy supply while minimizing weight and maintaining a compact, waterproof, and stable connection between the power supply and power wire, particularly with replaceable power supplies.
Innovation Solution
A connection arrangement featuring a detachable power supply and power wire with an elastic buckle and clamping slot, utilizing a fixed holder with a through hole and elastic clamping portions to secure the connection, and a hollow-carved design for reduced weight and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a replaceable power supply is used, then the power supply can be replaced and charged separately, but the installation and locking structure becomes larger and heavier
Solution Approach 1:
The power supply system is segmented into detachable components: the power supply unit can be separated from the headlamp body through a simplified locking mechanism. This segmentation allows independent replacement and charging of the power supply without requiring a complex integrated locking structure, thereby reducing overall weight while maintaining replaceability.
Solution Approach 2:
The power supply is extracted as an independent replaceable module from the headlamp system. By taking out the power supply and providing a simple receptacle structure in the headlamp body, the design eliminates the need for heavy-duty locking mechanisms while enabling easy replacement and separate charging of the power supply unit.
2Adaptability or versatility
If a replaceable power supply with contacts is used, then the power supply can be replaced, but the connection structure becomes heavier and poor in waterproof effect
Solution Approach 1:
The traditional contact-based connection structure is replaced by extracting the power supply as a separate module with a simplified receptacle. This extraction eliminates complex contact structures that compromise waterproofing, while the receptacle design inherently provides better environmental sealing.
Solution Approach 2:
The receptacle structure incorporates sealing elements and protective coverings that create a waterproof barrier between the headlamp body and the power supply. This shell-based approach provides effective waterproof protection while maintaining the replaceable nature of the power supply.
3Device complexity
If a fixed power supply is used, then the structure is simpler, but the volume is larger and the weight is heavier
Solution Approach 1:
The power supply system is segmented into a fixed headlamp body with a simple receptacle and a separate power supply unit. This segmentation maintains structural simplicity in the headlamp while allowing the power supply weight to be optimized independently through modular design and material selection.
Solution Approach 2:
The power supply unit utilizes lightweight materials and optimized dimensional parameters to reduce weight while maintaining necessary structural integrity. The receptacle in the headlamp body is designed with minimal necessary structure, changing the parameters of both components to achieve weight reduction without significantly increasing overall complexity.
