Split Headlamp Battery Connection With Elastic Buckle Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Split type headlamps face challenges in minimizing weight and head load while ensuring energy supply, as existing designs with replaceable power supplies are bulky, heavy, and poorly waterproof due to large installation and locking structures.
Innovation Solution
A connection arrangement featuring a headlamp band with a fixed holder and elastic buckle system that securely attaches the power supply and power wire, using a clamping slot and through hole for stable and waterproof connections, reducing component count and volume through a hollow-carved design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a replaceable power supply with installation and locking structure is used, then the power supply can be replaced, but the volume and weight increase and waterproof effect deteriorates
Solution Approach 1:
The patent combines the installation structure and locking structure into an integrated fixed holder that is directly formed on the headlamp band. The fixed holder includes installing portions that directly engage with the headlamp band and locking portions that secure the power supply, eliminating the need for separate installation and locking components. This integration reduces the overall volume while maintaining replaceability functionality.
Solution Approach 2:
The fixed holder serves multiple functions simultaneously: it provides installation attachment to the headlamp band, locking engagement with the power supply, and structural support. The integrating portions and locking portions work together as a unified multi-functional structure that reduces component count and volume while enabling power supply replacement.
2Adaptability or versatility
If a replaceable power supply with installation and locking structure is used, then the power supply can be replaced, but the weight increases
Solution Approach 1:
The patent merges the installation and locking functions into a single integrated fixed holder structure that is directly formed on the headlamp band. This consolidation eliminates redundant components and reduces the overall weight of the power supply installation system while maintaining the ability to replace the power supply.
Solution Approach 2:
The patent extracts the installation and locking structures from the power supply itself and relocates them to the headlamp band as a fixed holder. This separation allows the power supply to be lighter while the installation/locking functionality resides in the headlamp band structure, reducing the weight burden on the replaceable power supply unit.
3Adaptability or versatility
If a replaceable power supply with installation and locking structure is used, then the power supply can be replaced, but the waterproof effect deteriorates
Solution Approach 1:
The patent integrates the power supply connection and sealing functions into the fixed holder structure on the headlamp band. The locking portions and installing portions are designed as a unified structure that maintains waterproof sealing while enabling power supply replacement, preventing water ingress at the connection interface.
4Reliability
If a fixed power supply is used, then the power supply is stable, but the volume and weight increase
Solution Approach 1:
The patent segments the power supply system into a fixed holder portion on the headlamp band and a separate replaceable power supply unit. This segmentation allows the power supply to be smaller and lighter while the fixed holder provides the stable mounting and connection infrastructure, achieving both compactness and reliability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution provides a lightweight, stable, and waterproof connection that maintains power flow and prevents battery displacement, reducing head load and improving user experience by minimizing volume and weight while ensuring reliable energy supply.
Implementation Method 1
an elastic buckle is disposed at an outer side of the second end of the power wire, and the elastic buckle can cross the fixed holder and then snap into the clamping slot
