Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery chargers are inefficient in charging batteries of various sizes due to their fixed charging slots, leading to increased size and reduced usage efficiency.
Innovation Solution
A battery charger design featuring a guide part that is movable between a charging space and a support space, using guide pins or guide walls to adjust the storage space according to the size of the battery, ensuring proper positioning and efficient charging of batteries of different sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple slots of different sizes are provided to charge batteries of various sizes, then the charger can accommodate different battery sizes, but the overall size of the battery charger increases
Solution Approach 1:
The guide part is designed to be movable between a first position (protruding into the charging space) and a second position (retracted), allowing the charging space volume to dynamically adjust based on battery size. This enables a single charging slot to accommodate multiple battery sizes without increasing the overall charger size.
Solution Approach 2:
The guide part serves multiple functions: it guides battery insertion, adjusts the charging space volume, and enables a single slot to handle various battery sizes. This multi-functionality eliminates the need for multiple dedicated slots for different battery sizes.
2Adaptability or versatility
If multiple slots of different sizes are provided, then batteries of various sizes can be charged, but the efficiency is not maximized due to different usage amounts between slots
Solution Approach 1:
By making the guide part movable, a single charging slot becomes universal and can accommodate batteries of various sizes, ensuring consistent usage and maximizing charging efficiency without the inefficiencies of multiple underutilized slots.
Solution Approach 2:
The dynamic adjustment of the guide part allows the charging slot to adapt to different battery sizes, ensuring optimal space utilization and consistent charging efficiency across all battery types.
3Manufacturing precision
If the guide part is disposed protrusively in the charging space, then batteries can be properly positioned, but the charging space volume is reduced
Solution Approach 1:
The guide part moves between protruding (for positioning) and retracted (for maximizing volume) positions based on the charging needs, allowing the system to achieve both precise positioning and adequate charging space volume dynamically.
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
The solution allows for the efficient charging of batteries of various sizes, reducing the overall size of the charger and maximizing space efficiency while ensuring user convenience by maintaining proper battery alignment and contact for charging.
Implementation Method 1
when an external force is removed from the guide pin, the guide pin may move from the support space toward the charging space by a restoration force of the elastic body
