Removable Handle With Latch And Stylus Storage For Scanners
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current portable scanning devices have problematic handle detachment, lack ergonomic comfort, and inefficient stylus storage, leading to damage, misplacement, and operational interference.
Innovation Solution
A handle with a releasable connection mechanism, ergonomic grip, and integrated stylus storage, featuring a grip portion with a proximal end for coupling to the device housing, an actuator assembly for scanning functions, and a mechanical coupling system allowing easy attachment and detachment without tools, along with a stylus receptacle for secure storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the handle is permanently bonded to the housing, then the structural strength is improved, but the ease of removal deteriorates
Solution Approach 1:
The handle is divided into a proximal portion and a distal portion, with the proximal portion being removable from the housing. This segmentation allows the handle to be easily detached and reattached, solving the contradiction between structural strength and ease of removal by enabling tool-free attachment/detachment while maintaining adequate connection strength during use.
Solution Approach 2:
The connection between the handle and housing is made dynamic rather than static. The proximal portion can be moved between an engaged position (providing structural strength) and a disengaged position (providing ease of removal). This dynamic capability resolves the contradiction by allowing the system to switch between strong connection and easy detachment states.
2Ease of operation
If the handle is made removable, then the ease of removal is improved, but the reliability of connection deteriorates
Solution Approach 1:
The proximal portion of the handle incorporates self-aligning and self-latching features that automatically ensure proper engagement with the housing when attached. The resilient arm with latch mechanism and the complementary slot geometry provide self-service alignment and securing, maintaining reliable connection without requiring complex fastening procedures or tools.
3Ease of operation
If the stylus is stored externally on the housing, then the accessibility is improved, but the risk of damage and misplacement increases
Solution Approach 1:
The stylus storage receptacle is nested within the proximal portion of the handle, which itself attaches to the housing. This nested arrangement provides protected storage for the stylus while keeping it accessible through the opening in the proximal portion, resolving the contradiction between accessibility and protection from damage/misplacement.
4Device complexity
If the trigger is made non-ergonomic, then the device complexity is reduced, but the comfort of operation deteriorates
Solution Approach 1:
The proximal portion of the handle is designed with ergonomically considerate features including a contoured trigger and grip surface that adapt to the user's hand shape. This local quality enhancement in the grip area provides comfort without significantly increasing overall device complexity, as the ergonomic features are integrated into the handle's basic structure.

AI summary
A handle for the housing of a portable computer has a grip portion for grasping by the hand of the user, a proximal end having a proximal surface for mating with an adjacent surface of the housing, and a distal end. The handle also has an actuator assembly for operating one or more scanning functions and is located in the grip portion. A releasable connection mechanism is positioned on the proximal surface and including an operable latch extending outwardly from the proximal surface adapted for engaging with the corresponding first slot in the adjacent surface of the housing. At least one protrusion extends outwardly from the proximal surface for engaging with the corresponding second slot in the adjacent surface of the housing. A control coupling is established once the proximal surface is mated with the adjacent surface through engagement of the releasable connection mechanism.
