POS Scanner Cooling Duct Isolates Airflow from Scale
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional point of sale (POS) terminal scales and scanners cannot operate with higher power chipsets due to airflow interference from fans and cooling components, leading to inaccurate weight readings and exposure to contaminants.
Innovation Solution
A ducting system that integrates fans, heat pipes, and fins to circulate air through a scanner tower without affecting the scale, using a flexible polymer design that snaps together and secures without fasteners, allowing for a cleaner and more minimalist aesthetic.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If fans and cooling components are added to cool high-power chipsets, then processing power is improved, but weight reading accuracy deteriorates due to airflow interference
Solution Approach 1:
The internal space is divided into separate functional zones: a cooling channel for air circulation and a weighing platform area. The duct system segments the airflow path to confine cooling airflow to specific regions, preventing it from reaching the scale platform and interfering with weight measurements.
Solution Approach 2:
The weighing platform is extracted or isolated from the cooling airflow path. By positioning the platform in a region not affected by cooling air currents and using ducts to direct airflow away from it, the harmful airflow interference is effectively removed from the measurement zone.
2Temperature
If vents are opened for cooling airflow, then heat dissipation is improved, but contamination exposure worsens
Solution Approach 1:
Ducts serve as intermediary structures that connect internal cooling components to external airflow sources. These ducts provide a controlled pathway for air intake and exhaust, allowing heat dissipation while filtering or directing airflow to minimize contaminant entry into the terminal interior.
Solution Approach 2:
Flexible ducting material is used to create sealed yet adaptable air pathways. The flexible nature allows the ducts to conform to internal geometries while maintaining sealed connections, preventing contaminant leakage while enabling efficient cooling airflow through the terminal structure.

AI summary
Disclosed is duct for a scanner for a point of sale terminal. The duct may include a first body portion and a second body portion. The first body portion may have a first edge and a second edge. The second body portion may have a third edge. The second body portion may be connected to the first body portion so as to define a duct cavity. The first edge may define a duct cavity exhaust opening. The second edge and the third edge may define a duct cavity inlet opening.
