Deployable Appendage Power Tool Hinge Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional power tools are often too large, loud, or unsuitable for portable use in applications like funeral casket operations, requiring a compact and quiet solution for turning, tightening, or loosening components.
Innovation Solution
A compact power tool with a deployable motor-driven appendage that stows within a housing, featuring a hinge mechanism with gears allowing rotation between stowed and deployed positions, and a sound-dampening design for quiet operation, enabling it to fit in a pocket or hand and operate casket mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If conventional power tools are used, then they can turn, tighten, or loosen components, but they are too large and bulky for portable use
Solution Approach 1:
The appendage is nested within the housing when not in use, allowing the tool to maintain a compact form factor while still providing full functionality when deployed. The appendage can be stored inside the housing and deployed outward when needed, effectively hiding the larger component within the smaller overall tool structure.
Solution Approach 2:
The tool transitions from a static compact form to a dynamic deployed form through the hinge mechanism. The appendage can rotate between a stowed position (within the housing) and a deployed position (extending outward), allowing the tool to adapt its size and shape based on operational needs while maintaining portability when not in use.
2Object-generated harmful factors
If conventional power tools are used, then they can perform mechanical operations, but they produce excessive noise
Solution Approach 1:
The noisy motor component is extracted and isolated within the housing, separated from the external environment. This allows the motor to generate full mechanical power internally while the housing acts as a barrier containing the noise, preventing it from propagating to the external environment where users would be exposed to it.
Solution Approach 2:
The housing serves as an intermediary barrier between the noisy motor and the external environment. It transmits the mechanical power needed for operation while blocking and dampening the noise, effectively mediating between the high-power motor and the noise-sensitive external environment.
3Volume of moving object
If the appendage is made deployable to reduce tool size, then the tool becomes more compact, but the mechanism complexity increases
Solution Approach 1:
The appendage is divided into a secured portion (anchored within the housing) and an unsecured portion (free to deploy). This segmentation allows the appendage to function as both a structural component and a deployable element, reducing the need for complex locking and unlocking mechanisms while maintaining stability when deployed.
Solution Approach 2:
The hinge mechanism provides a simple dynamic connection that allows the appendage to rotate between stowed and deployed positions without requiring complex locking systems. The dynamic nature of the hinge allows for easy deployment and retraction while maintaining structural integrity during operation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The tool provides a convenient, quiet, and portable solution for tasks like coffin adjustments, fitting within a pocket or hand, and effectively operates casket mechanisms without the noise and bulk of traditional power drills.
Implementation Method 1
A power tool can include a motor that drives an appendage. The appendage can be rotated by the motor in order to turn, tighten, or loosen a component
Implementation Method 2
The hinge can include a set of gears that allow the appendage to rotate between the stowed and deployed positions, but also allow the motor to rotate the appendage about a longitudinal axis of the appendage

AI summary
The present disclosure relates to a power tool. The power tool can include an outer casing forming a housing, a motor, and a motor-driven appendage. The power tool can include a hinge mechanism having a hinge axis between an appendage-leg and a motor-leg, the appendage-leg comprising the motor-driven appendage and the motor-leg comprising an output shaft affixed to the motor. The housing can have an appendage port adjacent to the secured portion and capable of housing the unsecured portion. The motor-driven appendage can move between the closed state and the open state by hinging about the hinge axis and by passing through the aperture, laterally.
