Solution Overview
Problem
Existing mobile power supply devices with batteries lack effective protection against external damage, such as mechanical impact and environmental factors like moisture, during transportation and use.
Innovation Solution
A battery housing design that suspends the battery using an elastic bracket, providing mechanical protection and cushioning against impacts, while also incorporating a cover plate for sealing and cooling, and a support frame for enhanced stability and handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the battery is directly mounted in the housing, then the device structure is simple, but the battery is vulnerable to mechanical damage during impact
Solution Approach 1:
A battery holder is introduced as an intermediary component between the battery and the housing. The holder suspends the battery at a distance from the housing walls, preventing direct transmission of impact forces to the battery during drops or collisions, thereby protecting the battery while maintaining a relatively simple overall structure
Solution Approach 2:
The battery holder is designed with elastic material that provides cushioning before impact occurs. The elastic properties of the holder material absorb and dissipate impact energy during drops or collisions, protecting the battery from mechanical damage before the force can reach the battery cells
2Strength
If the housing is made of rigid material for structural strength, then mechanical protection is good, but impact forces are transmitted directly to the battery
Solution Approach 1:
The device combines rigid housing material for structural strength with elastic holder material for impact absorption. The housing provides overall structural integrity and protection, while the elastic battery holder material absorbs and dissipates impact forces, creating a composite protection system that leverages the advantages of both rigid and elastic materials
Solution Approach 2:
The holder material is selected with specific elastic parameters (modulus of elasticity, damping characteristics) that allow it to deform under impact loads and return to its original shape. This parameter optimization enables the holder to absorb impact energy effectively while maintaining the battery in a protected position
3Reliability
If the battery is suspended at a distance from the housing walls, then impact protection is improved, but the device volume increases
Solution Approach 1:
The battery holder provides suspension and protection only at critical locations where impact forces would directly transmit to the battery, rather than requiring uniform spacing throughout the entire housing. This localized quality approach maintains compact overall dimensions while providing effective protection at the battery mounting points
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 effectively protects the battery from mechanical damage and environmental factors, ensuring reliable operation and extended lifespan by absorbing impact forces and maintaining a dust-tight, moisture-tight environment with improved cooling capabilities.
Implementation Method 1
The mount can be made of an elastic material that allows at least a certain degree of elasticity, particularly in the case of high forces or accelerations
Implementation Method 2
Plastic has a certain elasticity, so that if the device hits the ground, for example, the impact forces are at least partially elastically absorbed in the housing before the impact forces are transmitted to the battery via the holder
