Battery Mounting Mechanism for Electric Work Machines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric mower designs require significant user effort to install and remove batteries, and often result in terminal misalignment, which can lead to deformation and impaired electrical connection or damage.
Innovation Solution
The electric power equipment features a battery receiving recess with a projection and grip on the battery, along with a supporting surface and spring members, allowing for easy installation and removal through rotational movement, and includes terminal protection pieces to prevent misalignment and damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the battery is secured using an elastic belt on a bracket, then the battery can be fixed to the main body, but the installation and removal process becomes complex and requires significant user effort
Solution Approach 1:
The battery securing mechanism is segmented into a latch member with engaging protrusions and corresponding engaging grooves on the battery case, replacing the continuous elastic belt constraint with discrete engagement points that allow simple snap-in/snap-out operation
Solution Approach 2:
The complex elastic belt securing system is extracted and replaced with a simplified latch mechanism that provides sufficient fixation strength through geometric interlocking rather than continuous mechanical constraint
2Ease of operation
If the battery is detachably mounted using rails, then the battery can be easily installed and removed, but terminal misalignment may occur causing deformation or damage
Solution Approach 1:
The battery case is preliminarily shaped with recesses and the latch member is preliminarily positioned to ensure that when the battery is inserted, the terminals automatically align with the receiving recesses before the latch engages, preventing misalignment damage
Solution Approach 2:
The latch member acts as an intermediary that first guides the battery into proper alignment through its engaging grooves and then secures it in place, ensuring terminal alignment occurs before final fixation
