Motor-Driven Tool Magazine Slide Mechanism for Sealed Housing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hand-held motor-driven machine tools have a large opening on the housing for manual operation, making them prone to dirt and contaminant entry, and limiting design flexibility due to the long displacement path required for the handle, which restricts the placement of other components.
Innovation Solution
A motor-driven machine tool design that couples the slide-over element to a transmission device with gear wheels, converting rotational movement into linear movement, allowing for a compact and sealed operation with a rotary knob or disk control, reducing the required housing space and enhancing sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a manually operable push-over element with a handle is used to push tools into the tool holder, then the tool can be pushed over into the tool holder, but the handle requires a relatively long displacement path on the upper side of the housing, resulting in a large opening that facilitates entry of dirt or contaminants
Solution Approach 1:
The patent replaces the manual push-over handle with an automated motor-driven push-over device. The motor (220) automatically pushes the tool (101) from the tool magazine (102) into the tool holder (104), eliminating the need for a large manual opening in the housing. This substitution of manual mechanical operation with automated mechanical operation resolves the contradiction by maintaining tool change functionality while sealing the housing against contaminants.
Solution Approach 2:
The patent introduces a motor-driven push-over device as an intermediary between the control system and the tool magazine/tool holder. This intermediary device (comprising motor 220, drive mechanism 221, and push-over element 219) performs the tool change operation automatically through sealed pathways, eliminating the need for direct manual access through large openings and thus preventing contaminant entry.
2Ease of operation
If a manually operable push-over element with a long displacement path is used, then the tool can be pushed over, but the housing design is restricted and other conditional elements must be arranged at other locations
Solution Approach 1:
The patent replaces the manual handle operation with an automated motor-driven system. The motor (220) and its drive mechanism (221) are integrated within the housing, eliminating the need for large external openings. This allows the housing to be designed more freely with optimized component placement and improved ergonomics, as the automated system requires minimal external access points.
Solution Approach 2:
The patent integrates the motor-driven push-over device components within the existing housing structure. The motor (220), drive mechanism (221), and push-over element (219) are nested within the housing interior, allowing compact arrangement and flexible housing design without requiring large external openings for manual handle operation.
3Object-affected harmful factors
If a motor-driven push-over device is used to automatically push tools, then the housing can be sealed better, but the device complexity increases
Solution Approach 1:
The patent replaces complex manual operation mechanisms with a simplified motor-driven system. The motor (220) directly drives the push-over element (219) through a compact drive mechanism (221), eliminating the need for long manual displacement paths and large sealed openings. This substitution reduces sealing complexity while adding only a simple motor actuation system.
Solution Approach 2:
The motor-driven push-over device operates automatically based on tool change requirements, eliminating the need for manual intervention. The system self-regulates the tool change process through the motor (220) and control system, reducing the complexity of manual sealing mechanisms while maintaining effective contaminant prevention through automated operation.

AI summary
The invention relates to a motor-powered machine tool (10), in particular a hand-held machine tool, comprising a drum-like tool-changing magazine (12) having tool chambers, which is arranged inside a housing (24), wherein in a change position one of the tool chambers of the tool-changing magazine (12) is aligned with a tubular tool holder (14; 54), and further comprising a sliding element (15) for sliding a tool (101) from the tool-changing magazine (12) into the tool holder (14; 54) and from the tool-changing magazine (12) back into the tool holder (14; 54), said sliding element being movable in a longitudinal direction of the tool holder (14; 54). According to the invention, the sliding element (15) is coupled with a gearbox system (20) comprising at least one toothed gear (18, 18a, 18b, 19, 19a, 19b), the rotational motion of which is translated into linear movement of the sliding element (15).
