Ergonomic Cover for Portable Scanning Device Grip
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current portable scanning devices often have bulky handles and compartment covers that are not ergonomically designed, making them uncomfortable to hold and operate with one hand, especially in field situations where a handle may not be suitable.
Innovation Solution
A portable terminal assembly with a cover that can be coupled to the enclosure, allowing for grasping by a user's finger, featuring a housing with a mating surface that extends outwardly from the back surface, providing a space for the user's fingers and thumb to operate the device comfortably without a handle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a handle is provided for scanning device, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The cover is extracted as a separate component from the main enclosure, allowing it to function as an independent grip element. The cover can be removed or adjusted, providing ease of operation without permanently increasing device complexity. This separates the gripping function from the main device structure.
Solution Approach 2:
The cover is divided into distinct functional portions including grip portions with finger engagement features, sealing portions, and mounting portions. This segmentation allows each portion to be optimized for its specific function while maintaining overall simplicity of the device assembly.
2Strength
If compartment covers are made bulky, then protection is improved, but ease of operation deteriorates
Solution Approach 1:
The cover is designed with non-uniform thickness and structure - thicker and more robust in areas requiring protection (sealing portions, mounting portions) while thinner and more contoured in areas requiring finger access (grip portions). This local differentiation provides both protection and ease of operation.
Solution Approach 2:
The cover incorporates curved and contoured surfaces including arcuate finger engagement features and rounded edges that conform to finger shapes. These curved geometries provide ergonomic grip while maintaining adequate protection, replacing flat bulky designs.
3Ease of operation
If cover sidewalls are spaced apart from enclosure sidewalls, then ease of operation is improved, but manufacturing precision requirements increase
Solution Approach 1:
The cover and enclosure are designed with pre-established spacing relationships and alignment features (protrusions, recesses, mating surfaces) that guide assembly. This preliminary design of fit ensures that the spaced-apart configuration is achieved automatically during assembly, reducing the need for high-precision manual adjustment.
Solution Approach 2:
The cover includes self-aligning features such as protrusions that fit into recesses and mating surfaces that automatically position the cover at the correct spacing from the enclosure sidewalls. This self-positioning mechanism reduces manufacturing precision requirements by allowing the components to find their correct relative positions during assembly.

AI summary
An assembly comprising an enclosure having a distal end wall and a proximal end wall connected to a pair of sidewalls such that the enclosure walls connect the bottom surface to a top surface having a user interface to define an enclosure interior. The compartment is positioned in the enclosure interior. A cover is included for coupling to the compartment situated in an opening in the bottom surface at a proximal end of the enclosure, such that the cover is configured for grasping by a user with at least one finger. The cover housing includes a cover surface, a pair of cover sidewalls, a proximal cover end wall and a distal cover end wall such that the cover walls extend from the cover surface to define a cover interior. The cover housing also has a mating surface at a base of the cover housing and defined by said walls, such that the mating surface is configured to mate with the bottom surface of the enclosure. When assembled the pair of cover side walls extend outwardly from the back surface and each of the pair of cover sidewalls is inset as spaced apart from the corresponding side wall of the pair of sidewalls of the enclosure. Further, the distal cover end wall extends outwardly from the back surface and is adapted to be spaced apart from the corresponding distal end wall.
