Handy Scanner Holder for Dual-Mode POS Operability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dual-purpose POS terminal devices face usability issues due to the lack of a reading device that offers operability comparable to both handheld and fixed types, affecting efficiency for store clerks and customers.
Innovation Solution
A reading device comprising a handy scanner, an adjuster, and a pedestal that allows the handy scanner to be used in both handheld and stationary modes, with the adjuster surrounding the readable angular area of the sensor and the pedestal providing stable positioning, enabling operability similar to built-in and handheld devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a handy type reading device is used, then ease of operation is improved for store clerks, but operability deteriorates for customers using self-checkout
Solution Approach 1:
The reading device is designed with a detachable structure that allows it to switch between handheld and fixed modes. The holder can be attached to or detached from the POS terminal device, enabling the system to adapt dynamically to different operational contexts and user needs.
Solution Approach 2:
The reading device is designed to perform multiple functions by being usable in both handheld and fixed configurations. This multi-functionality allows it to serve different user groups (store clerks and customers) with different operational preferences using the same device.
2Ease of operation
If a stationary type reading device is used, then operability is improved for customers, but ease of operation deteriorates for store clerks
Solution Approach 1:
The reading device transitions from a purely stationary design to a dynamic system where the holder can be attached or detached. This allows the device to switch between providing stable fixed-mode operability for customers and flexible handheld usability for store clerks.
Solution Approach 2:
The reading device achieves universality by being effectively usable in both fixed and handheld modes, allowing it to cater to different user groups and operational scenarios with a single device design.
3Adaptability or versatility
If a handy type reading device is used, then adaptability is improved, but stability and reading angle deteriorate
Solution Approach 1:
The holder serves as an intermediary component that enables the reading device to function in both handheld and fixed modes. When attached to the POS terminal device, the holder provides the necessary stability and proper reading angle, while still allowing the device to be detached for handheld use when adaptability is needed.

AI summary
A reading device includes: a handy scanner; an adjuster; and a pedestal. The handy scanner includes a head incorporating a reading sensor and a handle which is a gripping part having one end portion connected to the head, and configured to read a code symbol image by the reading sensor. The adjuster is attached to the head and surrounds a readable angular area of the reading sensor. The pedestal is a portion to which the adjuster is detachably coupled, and holds the adjuster in such a direction that the readable angular area of the reading sensor is substantially equal in an up-down direction with respect to a horizontal direction.
