POS Display Height Adjustment via Detachable Pole Coupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing POS terminal devices require an extension and contraction mechanism to adjust the height of customer-side display devices, increasing costs and hindering device downsizing due to the need for additional space, which complicates the installation process.
Innovation Solution
A display device with a coupling structure that allows direct coupling between the casing and display unit, using a separable columnar pole that can be mounted between them, enabling height adjustment without an extension and contraction mechanism, and allowing 360° rotation to accommodate various installation heights.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an extension and contraction mechanism is provided to adjust the height of the customer-side display device, then the height adjustment capability is improved, but the cost increases and the device size increases
Solution Approach 1:
The coupling structure is divided into multiple detachable components: a coupling portion on the display device, a separate pole with columnar shape, and a coupling portion on the casing. These segments can be assembled and disassembled independently, allowing height adjustment without requiring a complex extension and contraction mechanism. The pole can be separated into multiple sections for easy installation and storage.
Solution Approach 2:
The coupling structure transitions from a static direct-coupling design to a dynamic configurable design. The display device can be coupled to the casing in multiple states: directly coupled, coupled via a single pole, or coupled via multiple segmented poles. This dynamic reconfigurability provides height adjustment capability while maintaining structural simplicity.
2Adaptability or versatility
If an extension and contraction mechanism is provided, then the height adjustment capability is improved, but the space required for accommodating the mechanism increases, hindering downsizing
Solution Approach 1:
The height adjustment function is extracted from the main device body and implemented through a separate, removable pole that can be mounted between the display device and the casing. This externalizes the adjustment mechanism, eliminating the need for internal extension and contraction mechanisms within the device housing, thereby reducing the device volume while maintaining height adjustability.
Solution Approach 2:
Instead of providing height adjustment through vertical extension mechanisms within the device, the solution moves the adjustment capability to the coupling interface between the display device and the casing. The pole extends in the vertical dimension externally, allowing height adjustment without increasing the footprint or internal volume of the device itself.
3Adaptability or versatility
If a pole is provided for coupling, then the height adjustment capability is improved, but the installation complexity increases due to the need for specialized tools and procedures
Solution Approach 1:
The coupling structure is designed with self-aligning features and tool-free assembly mechanisms. The pole includes coupling portions that automatically align with the coupling portions on the display device and casing, eliminating the need for specialized installation tools. The design allows end-users to perform the coupling and height adjustment themselves without requiring professional installation services.
