Remote-Control Hand Tool Attachment for Hard-to-Reach Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hand tools lack remote control capabilities, making it difficult to access and operate in hard-to-reach areas, and existing remote control solutions are not efficiently integrated with the tool's actuating mechanism.
Innovation Solution
A hand tool design featuring a removable attachment part with a handling extension that allows remote control via a radio interface, where the attachment part is designed to actuate the tool's button, and a radio receiver and control unit convert signals into working motions, enabling the tool to be operated from a distance with enhanced accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the hand tool is equipped with remote control capabilities via a removable attachment part, then the ease of operation in hard-to-reach areas is improved, but the device complexity increases
Solution Approach 1:
The remote control system is divided into separate components: a removable attachment part with radio receiver, and a separate control device with radio transmitter. This segmentation allows the hand tool to gain remote control capability without permanently integrating complex electronics, thus improving ease of operation while limiting the increase in device complexity to only when the attachment is actually used.
Solution Approach 2:
The attachment part serves multiple functions: it acts as a mechanical coupling element for manual operation, a radio receiver for remote control, and provides a mounting interface for the handling extension. This multi-functionality reduces the need for separate components, thereby managing device complexity while enhancing operational versatility.
2Reliability
If the attachment part is designed to mechanically actuate the actuating button, then the reliability of signal transmission is improved, but the device complexity increases
Solution Approach 1:
The attachment part combines mechanical and electronic functions into a single integrated component. The housing section serves both as a mechanical actuator for the button and as a mounting structure for the radio receiver, while the pivot joint region provides both mechanical linkage and a mounting point for the antenna. This merging reduces the number of separate components, thereby limiting device complexity while ensuring reliable signal transmission through dedicated mechanical actuation.
3Ease of operation
If a handling extension is provided for remote operation, then the ease of operation in difficult-to-access areas is improved, but the device complexity increases
Solution Approach 1:
The handling extension is designed to be mounted on the attachment part, creating a nested configuration where the extension can be attached or removed as needed. This nesting approach allows the system to gain extended reach capability only when necessary, improving ease of operation in difficult-to-access areas while avoiding the permanent presence of additional complex structures.

AI summary
A hand-held tool that is prepared for remote control has a handle region, an actuating button, and a removable attachment part held in the handle region. The attachment part has a handling extension and a collar encompassing the handle region. The collar includes first and second collar parts pivotably connected together. The attachment part acts upon the actuating button. The actuating button is displaced into an actuating position by a housing section of the collar for a duration of an arrangement of the attachment part on the handle region.
