Hand-Held Power Tool Guide Rail Carrying Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing guide rails for hand-held power tools are unwieldy and difficult to transport due to their elongate shape, lacking adequate carrying comfort.
Innovation Solution
A carrying device with a carrying body and a handle that engages form-fitting contours on the guide rail, allowing for comfortable gripping and support, featuring a through-opening for the handle to be inserted between the guide and contact faces, and optionally including hooks for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the guide rail is designed with an elongate shape to provide desired guide properties, then the guide functionality is improved, but the guide rail becomes unwieldy and difficult to transport
Solution Approach 1:
The guide rail is segmented into a stationary guide rail portion and a movable carrying device portion. The carrying device can be attached to and detached from the guide rail, allowing the guide rail to remain fixed while the carrying device is transported separately or independently.
Solution Approach 2:
A carrying device acts as an intermediary between the operator and the guide rail. This carrying device with its handle provides a means to transport the guide rail without requiring direct handling of the elongate guide rail itself, thus resolving the transportability issue while preserving guide functionality.
2Reliability
If the guide rail is made elongate to extend along the workpiece, then the guiding capability is improved, but the carrying comfort deteriorates
Solution Approach 1:
The system separates the guiding function (stationary guide rail) from the carrying function (movable carrying device). This segmentation allows the guide rail to be optimally designed for guiding capability without compromise on carrying comfort, as the carrying device handles all transport operations.
Solution Approach 2:
The carrying device serves as an intermediary that assumes the burden of carrying the elongate guide rail. With a carrying length of at least one-third of the guide rail length, it provides ergonomic handling and distributing the weight, thereby improving carrying comfort while maintaining full guiding capability.
3Area of stationary object
If the guide rail has a substantial length to cover the workpiece, then the coverage is improved, but the handling difficulty increases
Solution Approach 1:
The guide rail system is divided into a fixed guide rail portion that provides extensive coverage along the workpiece, and a separate carrying device that can be easily attached and detached. This allows the guide rail to extend over large areas without compromising handling ease, as the carrying device manages all transport operations.
Solution Approach 2:
The carrying device acts as an intermediary that simplifies handling of the extensive guide rail. By providing a dedicated carrying mechanism with appropriate length and attachment features, it makes managing large-area coverage practical and easy to operate.

AI summary
A system including at least one guide rail (21, 22) which is provided for guiding a hand-held power tool (11), has an elongate shape and extends along a longitudinal axis, wherein the guide rail (21, 22) has, on mutually opposite sides, a contact face (24) for the guide rail (21, 22) to rest on a workpiece (W), and has a guide face (23), in front of which a longitudinal guide face (31), extending along the respective longitudinal axis (L1, L2), for guiding the hand-held power tool (11) protrudes parallel to the longitudinal axis (L1, L2). The system includes a carrying device (200) having a carrying body (201, 202) and a carrying handle (120), arranged on the carrying body (201, 202), to be grasped by an operator (BE), wherein the guide rail (21, 22) has, for connecting to the carrying device (200), form-fitting contours (34) which are able to be brought into engagement with mating form-fitting contours (124) of the carrying device (200) such that the guide rail (21, 22) is able to be carried by a user (BE) using the carrying handle (120).
