Battery Pack Protective Housing With Vibration-Decoupled Handle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery-operated machining devices lack effective protection for interchangeable battery packs while minimizing operator vibrational load during use.
Innovation Solution
A protective housing is fixedly connected to the housing part and movably coupled to the main handle, absorbing impact energy and providing vibrational decoupling through a mechanism that guides the handle laterally during falls or impacts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the protective housing is fixedly connected to the main handle, then the battery pack is well protected from impacts and falls, but the operator experiences higher vibrational load
Solution Approach 1:
The protective housing is segmented into two connection systems: fixed connection to the housing part for impact protection, and movable connection to the main handle for vibration decoupling. This segmentation allows each connection to serve its specific function independently.
Solution Approach 2:
The protective housing acts as an intermediary element between the housing part and the main handle. It transfers impact forces to the housing part while decoupling vibrations from the main handle, mediating between these two components to resolve the contradiction.
2Stability of the object's composition
If the protective housing is fixedly connected to both the housing part and the main handle, then structural stability is improved, but impact energy cannot be effectively dissipated
Solution Approach 1:
The connection between the protective housing and the main handle is made movable rather than fixed, allowing the system to dynamically respond to impacts. The movable connection enables the protective housing to move independently during impacts, facilitating energy dissipation through controlled movement and deformation.
3Reliability
If the protective housing completely surrounds the battery pack, then protection against impacts and falls is maximized, but the device complexity increases
Solution Approach 1:
The protective housing serves multiple functions simultaneously: it protects the battery pack from impacts, provides a structure for dual connection systems (fixed to housing part, movable to main handle), and enables vibration decoupling. This multi-functionality reduces the need for separate protective components.

Function Achieved in This Case
This design effectively reduces the risk of damage to the machining device by dissipating impact energy and minimizing vibrations, ensuring precise machining operations and easy replacement of parts.
Implementation Method 1
the protective housing can absorb any impacts and falls particularly well by dissipating the impact energy into the housing part
Implementation Method 2
a high level of vibrational decoupling can be achieved as a result of the movable coupling to the main handle

AI summary
A battery-operated machining device includes a housing part, which at least partially surrounds an electronic unit and/or an electric motor for operating the machining device, a main handle, which is movably connected to the housing part for vibrational decoupling, and at least one electromechanical interface, which is arranged on the main handle and is provided for receiving an interchangeable battery pack such that the interchangeable battery pack can be released without tools, wherein the electromechanical interface has a protective housing, the envelope of which completely surrounds the received interchangeable battery pack. The protective housing is fixedly connected to the housing part and movably coupled to the main handle.
