Twin-Latch Battery Mounting for Vibration-Stable Power Equipment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery systems in power equipment face issues with securing and withstanding operational vibrations, leading to wear and potential disconnection, especially for larger batteries, without increasing the assembly height.
Innovation Solution
A battery system featuring a spring-loaded, gear-driven mechanism with twin tapered latches and a gearing assembly that secures the battery in place, allowing for a tolerance band in stack height and minimizing the assembly's vertical dimension, while enabling easy attachment and detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If a battery system uses a simple mounting structure, then the assembly height can be minimized, but the battery cannot withstand operational vibrations and may become disconnected
Solution Approach 1:
The battery system divides the securing function into multiple independent latches (first latch and second latch) that can be distributed across different locations on the battery assembly, allowing each latch to provide localized securing without requiring a tall centralized locking mechanism
Solution Approach 2:
The latches are positioned to engage with the battery in a horizontal plane rather than requiring vertical space, allowing the securing mechanism to operate in a different dimension and thus minimize the assembly height while maintaining reliability
2Reliability
If a battery system uses a robust securing mechanism to withstand vibrations, then connection stability improves, but the device complexity increases
Solution Approach 1:
The spring-loaded latches automatically engage with the battery when inserted and automatically disengage when released, eliminating the need for complex manual operation mechanisms while maintaining reliable vibration resistance through the spring's continuous securing force
Solution Approach 2:
The spring mechanism and latch structure are combined into a single integrated component that provides both the securing force and the mechanical engagement in one element, reducing the number of separate parts and simplifying the overall mechanism while maintaining vibration resistance
3Reliability
If a battery system uses multiple latches to prevent disconnection, then connection stability improves, but the ease of operation decreases
Solution Approach 1:
Multiple latches are actuated simultaneously through a single release mechanism, combining the function of releasing multiple separate latches into one unified action that maintains connection stability while simplifying operation to a single motion
Solution Approach 2:
The latches are positioned and designed to engage and disengage in a coordinated sequence, with each latch independently positioned to secure different aspects of the battery, allowing them to be actuated together through a single release point while maintaining individual securing functions
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 secures the battery against operational vibrations, reducing wear and disconnection, while maintaining a compact design and facilitating easy installation and removal.
Implementation Method 1
A spring can engage the first latch and the second latch, the spring can bias the first latch and the second latch toward the locked position
Implementation Method 2
A gearing assembly can be attached to the battery and driving one of the first latch and the second latch between the locked position and the released position

AI summary
A battery system for a power equipment apparatus including a battery, a first latch and a second latch. The first latch and the second latch can be movable between a locked position where the first and second latches are configured to engage with a mating structure of the apparatus and a released position where the first and second latches are disengaged from the apparatus. A gearing assembly can be attached to the battery and driving one of the first latch and the second latch between the locked position and the released position. A spring can engage the first latch and the second latch, the spring biasing the first latch and the second latch toward the locked position.
