Detachable Cuff Extension for Remote Hand Tool Actuation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hand tools lack the capability for remote operation, particularly in hard-to-reach areas, and existing remote-controlled tools often require complex setups or tools for attachment and operation.
Innovation Solution
A detachable attachment part with a handling extension that allows for remote control of hand tools, enabling operation via a radio interface and actuation of the tool's actuation button, with an ergonomic design for user convenience and tool-free assembly/disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a remote control system is added to hand tools, then operational flexibility and accessibility to hard-to-reach areas is improved, but device complexity increases
Solution Approach 1:
The remote control system is segmented into separate modular components: a cuff attachment part that interfaces with the hand tool, a handling extension with radio transmitter, and the hand tool itself with radio receiver. This modular segmentation allows the remote control functionality to be added without redesigning the entire system, thus improving adaptability while managing complexity through component separation.
Solution Approach 2:
The cuff attachment part serves multiple functions: it mechanically attaches the handling extension to the hand tool, provides structural support for the radio components, and acts as a mounting platform for the remote control interface. This multi-functionality reduces the need for separate dedicated components, thereby adding remote operation capability without proportionally increasing overall system complexity.
2Ease of operation
If a detachable attachment part is used for remote control, then ease of assembly and disassembly is improved, but connection reliability may worsen
Solution Approach 1:
The attachment system transitions from a static permanent connection to a dynamic detachable connection. The cuff is designed with movable clamping elements that can be easily opened and closed to attach or detach the handling extension. This dynamic design maintains ease of assembly while ensuring reliable connection during operation through secure mechanical engagement features such as locking mechanisms and precise fitting surfaces.
Solution Approach 2:
The cuff attachment part acts as an intermediary component between the handling extension and the hand tool. It provides a standardized interface with complementary mating features that ensure reliable mechanical and electrical connections. The intermediary cuff absorbs the complexity of the connection mechanism, allowing simple attachment and disassembly while maintaining connection reliability through its engineered interface design.
3Adaptability or versatility
If the actuation button is permanently displaced into actuation position by the cuff, then remote actuation is enabled, but manual operation capability is lost
Solution Approach 1:
The actuation button mechanism is designed to be dynamic rather than fixed. The cuff displaces the button into the actuation position when attached, enabling remote control functionality. However, the button can still be manually pressed by the user when needed, providing operational flexibility. This dynamic design allows the system to adapt between remote and manual operation modes as required.
Solution Approach 2:
The system provides self-service capability by allowing the user to switch between remote and manual operation modes as needed. The actuation button remains accessible and functional for manual operation even when the cuff is attached and displacing it into the actuation position. This self-service feature ensures that the tool can operate autonomously in either mode without requiring external assistance or complex switching mechanisms.
