Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a concealment device is added to cover the input keypad, then user privacy is improved, but device complexity increases
Solution Approach 1:
The privacy shield is integrated within the housing structure of the automated banking machine, nesting the privacy protection function within the existing device framework. The shield forms an internal cavity that houses the keypad while providing external privacy coverage, effectively combining structural support and privacy protection in a single integrated component.
Solution Approach 2:
The privacy shield acts as an intermediary element between the user and the surrounding environment. It provides indirect viewing capability through strategically positioned transparent or translucent portions that allow users to see their inputs while blocking the view of unauthorized observers, thus mediating the interaction between user privacy needs and operational functionality.
2Reliability
If convex mirrors are added for user privacy monitoring, then security is improved, but device complexity increases
Solution Approach 1:
The convex mirrors are positioned on the exterior surface of the housing, utilizing the external dimensional space rather than requiring internal integration. This allows the security monitoring function to be added without significantly increasing internal device complexity, as the mirrors operate in the external spatial dimension to provide surveillance capability.
3Reliability
If the machine is designed with weather-resistant features, then reliability in outdoor environments is improved, but manufacturing complexity increases
Solution Approach 1:
The housing is constructed using composite materials that combine durability and weather resistance with manufacturability. The use of molded plastic or metal composite structures allows the housing to withstand outdoor environmental conditions while maintaining ease of manufacturing through standardized production processes.
4Reliability
If indirect viewing mechanism is implemented for keypad, then user privacy is improved, but ease of operation decreases
Solution Approach 1:
The privacy shield incorporates localized transparent or translucent portions at specific key areas, providing privacy protection only where needed while maintaining operational ease. These strategically positioned transparent sections allow users to see their inputs clearly without requiring them to remove the shield, thus maintaining ease of operation while providing targeted privacy protection.
