Electric Work Machine Housing Interface for Controller Impact Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electric work machines often experience breakage of controllers and surrounding components due to external forces, such as falls, which can lead to deformation and damage.
Innovation Solution
Incorporating a deformation reducing member at the interface between the grip and controller compartment in the electric work machine's housing to absorb and distribute external forces, reducing the likelihood of deformation and breakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the housing is made rigid to maintain structural integrity, then strength is improved, but deformation and breakage occur under external forces
Solution Approach 1:
A deformation reducing member is incorporated into the housing at the interface between the grip and controller compartment to absorb external forces before they reach the controller. This cushioning element is pre-installed to mitigate the impact of drops or collisions, protecting the controller from deformation and breakage while maintaining overall housing strength.
2Reliability
If the controller is protected from external forces, then reliability is improved, but the housing structure becomes more complex
Solution Approach 1:
The deformation reducing member acts as an intermediary element positioned between the external environment and the controller. This mediator absorbs and distributes external forces, preventing direct transmission to the controller while maintaining a relatively simple overall housing structure without requiring complex protective mechanisms.
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 deformation reducing member effectively minimizes the risk of controller and component breakage by absorbing external forces, enhancing the durability and reliability of the electric work machine.
Implementation Method 1
a deformation reducing member located at an interface between the grip and the controller compartment to reduce deformation of the housing

AI summary
Breakage of a controller in an electric work machine and components around the controller is reduced. The electric work machine includes a motor, a trigger switch operated to activate the motor, a controller that controls the motor, a housing including a grip on which the trigger switch is located and a controller compartment accommodating the controller, and a deformation reducing member located at an interface between the grip and the controller compartment to reduce deformation of the housing.
