Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Barcode scanning devices lack versatile accessories that enable efficient and stable operation in both handheld and presentation modes, requiring improved functionalities for enhanced usability and versatility.
Innovation Solution
A barcode reader assembly comprising a reader and a stand with a mechanical linkage allowing rotational movement and secure mounting, featuring a resilient finger component with a protrusion for easy coupling and decoupling, and a curved design for minimal clearance and frictional engagement, enabling selective rotation and locking of the reader relative to the stand.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the barcode reader is designed for handheld operation, then portability and ease of operation are improved, but stability and positioning accuracy deteriorate
Solution Approach 1:
The barcode reader is designed with a universal stand mechanism that enables it to function in both handheld mode and presentation mode. The stand attaches to the reader base, providing a stable mounting surface while maintaining the ability to detach for handheld operation, thus achieving multi-functionality across different operational contexts
Solution Approach 2:
The barcode reader is divided into separable components: a handheld reader unit and a separate stand assembly. The stand includes a mounting mechanism that can be attached to or detached from the reader base, allowing the system to be segmented into portable and stationary configurations as needed
2Stability of the object's composition
If the stand provides secure mounting, then stability is improved, but ease of coupling and decoupling deteriorates
Solution Approach 1:
The mounting mechanism is designed to be self-aligning and self-latching. The stand automatically positions itself relative to the reader base through geometric constraints, and the engagement is maintained through passive mechanical retention, eliminating the need for complex alignment procedures or additional fastening actions
Solution Approach 2:
The mounting mechanism transitions from a static locked state during presentation mode to a dynamic detachable state during handheld operation. The mechanical linkage allows for controlled engagement and disengagement through simple user input, providing adaptability between different operational modes
3Adaptability or versatility
If the reader allows rotational movement, then adaptability in positioning is improved, but risk of component interference and user injury deteriorates
Solution Approach 1:
A protective cover or guard mechanism acts as an intermediary between the rotating reader components and the user's hands. This intermediary element prevents direct contact with moving parts during rotation while still allowing the rotational motion to function properly, thereby eliminating injury risk without compromising positioning flexibility
Solution Approach 2:
The rotational mechanism utilizes curved or rounded motion paths instead of sharp angular movements. The reader rotates along a controlled arc within the stand structure, which naturally limits the range of motion to safe boundaries while maintaining full positioning adaptability across the desired field of view
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 solution provides a robust and versatile barcode reader assembly that allows for easy switching between handheld and presentation modes, ensuring stable and unobstructed rotation while minimizing the risk of component interference and user injury, with adjustable engagement forces for secure positioning.
Implementation Method 1
The mechanical linkage may include a resilient finger component having a protrusion extending therefrom
Implementation Method 2
The curved base surface of the reader base and the curved wall of the stand are nested such that a clearance of less than approximately 5 mm is formed between the curved base surface and the curved reader enclosure surface

AI summary
A barcode reader assembly for capturing at least one object appearing in a field of view (FOV) is provided that includes a reader and a stand. The reader includes a reader enclosure having a top portion and a bottom portion and a reader base including a curved base surface. The bottom portion of the reader enclosure is mechanically coupled to the reader base. The stand includes a platform and a wall extending therefrom in a generally upward direction. The reader base is mechanically coupled to the stand such that the reader is rotatable relative to the stand.
