Detachable Handle Actuator with Pivot and Raised Face for Ergonomic Scanning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current portable scanning device handles are difficult to remove without damaging the device, lack ergonomic comfort, and have inadequate stylus storage solutions, leading to user discomfort and stylus misplacement.
Innovation Solution
A handle with a grip portion and actuator assembly that allows for easy attachment and detachment from the portable terminal, featuring a pivot connection, biasing members, and a raised face portion for ergonomic interaction, along with a built-in stylus receptacle for secure storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the handle is molded as an integral portion of the housing or connected using fasteners, then the structural strength and stability are improved, but the ease of removal and replacement deteriorates
Solution Approach 1:
The handle is designed as a separate, detachable component from the housing rather than an integral part. The handle assembly includes a handle body with a proximal end that can be attached to or detached from the housing, allowing the handle to be segmented from the main device body. This enables easy removal and replacement while maintaining structural integrity when connected.
Solution Approach 2:
The connection between the handle and housing is designed to be dynamically changeable between attached and detached states. The proximal end of the handle body incorporates features that allow it to be connected to the housing in a use configuration and detached when needed, providing dynamic adaptability rather than a fixed static connection.
2Quantity of substance
If the stylus is attached externally to the housing or handle, then the stylus storage capacity is improved, but the risk of damage, misplacement, and interference with operation increases
Solution Approach 1:
The stylus is stored within a receptacle that is integrated into the handle body, creating a nested configuration where the stylus fits inside the handle structure. This internal storage solution protects the stylus from damage and misplacement while eliminating external attachment points that could interfere with device operation.
Solution Approach 2:
The stylus receptacle is merged with the handle body as an integrated feature rather than a separate external component. The receptacle is formed as part of the handle structure, combining the functions of the handle and stylus storage into a single unified assembly, which improves both security and operational efficiency.
3Device complexity
If the trigger is designed with a simple configuration, then the device complexity is reduced, but the ergonomic comfort for different hand sizes deteriorates
Solution Approach 1:
The actuator body is designed with a contoured shape that provides different surface characteristics at different locations. The actuator body includes a face portion with a raised portion that creates multiple actuator regions with varying geometries, allowing users to interact with the trigger using different fingers or hand positions while maintaining a relatively simple overall structure.
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
Enables easy handling and operation of portable scanning devices with ergonomic comfort, secure stylus storage, and improved usability by facilitating the operation of scanning functions without tools and reducing stylus misplacement.
Implementation Method 1
biasing member(s) for biasing the actuator body towards a first position
Implementation Method 2
actuator body connected at a proximal portion to the handle body by a pivot connection, facilitating rotation of the actuator body about the pivot connection

AI summary
A portable terminal having a handle configured for connection to an enclosure of the portable terminal, such that the portable terminal has one or more scanning functions for interacting with information objects 16 in a logistics environment. The handle has a handle body having a grip portion shaped for grasping by a hand of the user of the portable terminal, a proximal end of the grip portion for coupling to the housing of the portable terminal, and a distal end of the grip portion. An actuator assembly of the handle is configured for affecting the operation of one or more scanning functions and is positioned in an aperture of the handle body for access by one or more fingers of the user's hand. The actuator assembly includes an actuator body connected at a proximal portion to the handle body by a pivot connection, biasing member(s) for biasing the actuator body towards a first position, and a face portion of the actuator body configured for contacting with the one or more fingers such that the face portion has a raised portion for defining the plurality of actuator regions for interaction with the one or more fingers for facilitating rotation of the actuator body about the pivot connection for displacement from the first position to a second position into an interior of the handle body, wherein the displacement of the actuator body affects the operation of the one or more scanning functions (e.g. via activation of a switch by a control arm).
