Handheld Power Tool Charger Mounting System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing charger mounting systems for battery packs of handheld power tools are difficult to assemble and disassemble, often result in tilting or damage to the wall surface, and lack clear guidance for screw placement, leading to insecure attachment and potential falls.
Innovation Solution
A holding system with a detachable charger and holder that includes adjustable feet and latching mechanisms, allowing for easy assembly and disassembly, and featuring a defined angle to prevent battery packs from falling, along with a radio module for wireless communication and data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the charger is mounted using recesses and fastening elements (screws, hooks, rails), then the charger can be attached to the wall, but the assembly process becomes difficult and time-consuming, and the fasteners are not visible during attachment causing the charger to tilt and/or damage the wall surface
Solution Approach 1:
The mounting system uses self-aligning features where the charger housing itself guides the fastening elements into position through visible alignment marks and guide structures, eliminating the need for precise pre-drilling and allowing users to easily see and follow the mounting process without special tools or complex procedures
Solution Approach 2:
The mounting system separates the fastening function from the mounting bracket, using individual visible fastening elements that can be independently positioned and secured, allowing for easy adjustment and visible alignment during the mounting process
2Reliability
If screws are used to attach the charger, then the charger can be securely fastened, but it is not clearly defined how far the screws must protrude, leading to installation difficulties and potential falls
Solution Approach 1:
The mounting system incorporates visually distinct colored components and alignment marks that clearly indicate the correct screw protrusion depth and positioning, making the installation process intuitive and eliminating guesswork about fastener depth
Solution Approach 2:
The system includes pre-marked mounting positions and pre-configured fastening element lengths that are optimized for the specific charger weight and dimensions, eliminating the need for users to determine correct screw depths during installation
3Adaptability or versatility
If the charger is detachably mounted to allow frequent assembly and disassembly, then mobility and flexibility are improved, but the mounting security and reliability may be compromised
Solution Approach 1:
The mounting system employs a dynamic fastening mechanism that transitions between locked and unlocked states through a simple user action, providing secure attachment during use while enabling quick detachment when needed, with the security level adapting to the operational state
