Elastic Splash Guard for Hydraulic Tool Battery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hand-held, mains-independent power tools, particularly hydraulic fluid devices, are vulnerable to damage from liquid splashes, which can penetrate the battery block and cause significant damage, especially in outdoor applications.
Innovation Solution
A highly elastic, water-impermeable splash protection shell made of neoprene material with a base section, cover section, and side sections, featuring a larger second opening that allows the splash guard to be pushed up or turned inside out to expose the battery block during replacement, ensuring the tool remains functional and protected without the risk of the splash guard being lost.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a separate splash guard is provided for the battery block, then protection against liquid splashes is improved, but the complexity of the device increases
Solution Approach 1:
The splash guard is made from a highly elastic flat material that forms a flexible protective shell around the battery block. This flexible membrane provides effective liquid splash protection while maintaining a simple, lightweight structure that integrates easily with the existing power tool design.
2Object-affected harmful factors
If the splash guard completely encloses the battery block, then protection against liquid splashes is improved, but the ease of operation deteriorates due to difficulty in battery replacement
Solution Approach 1:
The splash guard is designed with a segmented structure featuring a first opening in the cover section and a second opening in the base section. These openings allow the battery block to be partially accessed and removed for replacement while the splash guard remains attached to the tool body, providing protection during operation and ease of maintenance when needed.
3Object-affected harmful factors
If the splash guard is made of rigid material, then protection against liquid splashes is improved, but the ease of manufacture deteriorates
Solution Approach 1:
The splash guard utilizes a highly elastic flat material that can be easily formed and molded into the required shape. This flexible material is simpler to manufacture than rigid protective structures, as it requires less precise machining and assembly, while still providing effective liquid barrier protection.
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 minimizes the risk of battery block damage from liquid splashes while allowing easy battery replacement and maintaining tool functionality, with the splash guard remaining attached and preventing liquid ingress through its design.
Implementation Method 1
a highly elastic, water-impermeable flat material, which casing comprises a base section, a cover section opposite the base section, and side sections connecting the cover section and the base section
Implementation Method 2
the splash guard is designed as a casing made of a highly elastic, water-impermeable flat material

AI summary
A handheld, non-mains-powered electric tool, in particular a handheld hydraulic fluid tool, comprises a tool body (1) including an electrical assembly, in particular an electrically operated pump, a handle (3) connected to the tool body and comprising a control element (2), and a battery pack (5). At the lower end of the handle (3) is a connection base (4) that is enlarged relative to the cross-section of the handle (3) and is designed for the interchangeable docking of the battery pack (5). The battery pack (5) is at least partially enclosed by a separate splash guard (6). This splash guard is designed as a casing made of a highly elastic, waterproof flat material, comprising a base section (7), a cover section (8) opposite the base section, and side sections (9) connecting the cover section (8) and the base section (7).The lid section (8) has a first opening (10) through which the handle (3) passes above the connection base (4); and the bottom section (7) is provided with a second opening (11) that is larger than the first opening (10).
