Battery Holder with Resilient Positioning for Dual Battery Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless transmitter and receiver devices require separate designs and certifications for disposable AA batteries and rechargeable lithium batteries due to size differences, leading to increased manufacturing and user inconvenience.
Innovation Solution
A battery holding mechanism with a battery holder and resilient positioning member that selectively accommodates either a single larger battery or two smaller batteries in a juxtaposed manner, allowing for adaptable installation based on user preference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the wireless transmitter and receiver device is designed for a specific battery size, then the battery positioning is stable, but the device can only accommodate one kind of battery
Solution Approach 1:
The battery holder is designed with a universal installation space that can accommodate different battery types (single large battery or two small batteries) through the same structural interface. The resilient positioning member adapts its positioning action based on the battery configuration, enabling one device design to serve multiple battery compatibility requirements without requiring separate device versions
Solution Approach 2:
The resilient positioning member provides dynamic adaptation to different battery configurations. When a single large battery is installed, the positioning member abuts against it directly; when two small batteries are installed, the positioning member abuts against one battery which in turn abuts against the other, creating a chain reaction that positions both batteries properly. This dynamic response eliminates the need for fixed, complex positioning structures for each battery type
2Adaptability or versatility
If separate device designs are made for different battery types, then the battery positioning is optimized for each type, but the manufacturing cost increases
Solution Approach 1:
The battery holder structure serves multiple functions: it can hold either a single large battery or two small batteries using the same physical structure. This universal design eliminates the need for manufacturers to create and certify multiple device versions for different battery types, directly reducing manufacturing complexity and associated costs while maintaining optimized positioning for each battery configuration
3Ease of manufacture
If the battery holder structure is simplified to accommodate different batteries, then the manufacturing cost decreases, but the battery positioning stability may be compromised
Solution Approach 1:
The resilient positioning member automatically adapts its positioning mechanism based on the battery configuration without requiring external intervention or complex control systems. When two small batteries are installed, the positioning member's action on one battery self-propagates to the other through abutment, creating stable positioning through the batteries' own mutual interaction rather than requiring separate positioning structures for each battery
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
Enables the same device to be used with either one rechargeable ICR-18500 lithium battery or two AA batteries, reducing manufacturing costs and user inconvenience while ensuring stable battery positioning and electrical contact.
Implementation Method 1
the resilient positioning member is disposed to resiliently abut against the first battery in a Z direction orthogonal to the X direction to thereby position the first battery within the battery holder

AI summary
A battery holding mechanism is adapted to selectively accommodate a first battery having a larger outer diameter, or two second batteries each having a smaller outer diameter. The battery holding mechanism includes a battery holder and a resilient positioning member. The battery holder defines therein an installation space configured to permit only the first battery or only the second batteries to be installed. When the first battery is installed, the first battery is positioned by the resilient positioning member. When the second batteries are installed, the second batteries are positioned by the resilient positioning member in a juxtaposed manner.
