Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If demonstration models are made accessible for testing, then ease of operation is improved, but security against theft deteriorates
Solution Approach 1:
The security system is divided into separate functional modules: a sensor assembly that detects removal attempts, a flexible circuit connector that establishes electrical communication, and a bracket system that provides physical mounting. This segmentation allows each component to be optimized independently while working together to solve the contradiction between accessibility and security.
Solution Approach 2:
The flexible circuit connector acts as an intermediary element that bridges the sensor assembly and the merchandise. It provides both electrical communication for operation and a detectable connection point for security monitoring, enabling the system to simultaneously support testing accessibility and theft prevention.
2Reliability
If security measures are added to prevent theft, then reliability is improved, but device complexity increases
Solution Approach 1:
The flexible circuit connector serves multiple functions simultaneously: it provides electrical power and data communication to the merchandise, establishes a detectable security connection, and enables the sensor to monitor removal attempts. This multi-functionality reduces the need for separate dedicated security components, thereby limiting complexity increase.
Solution Approach 2:
The flexible circuit board provides a thin, adaptable connection medium that can be integrated into the existing merchandise structure without adding significant bulk or complexity. Its flexibility allows it to conform to various device geometries while maintaining reliable electrical and security connections.
3Ease of operation
If the sensor is made removable from the bracket, then ease of operation is improved, but security deteriorates
Solution Approach 1:
The bracket assembly incorporates movable bracket arms that can transition between engaged and disengaged positions. When engaged, they prevent sensor removal; when disengaged, they allow easy sensor removal for replacement or maintenance. The dynamic nature of this mechanism resolves the contradiction between security and ease of operation.
Solution Approach 2:
The sensor assembly includes detection circuitry that monitors the engagement state of the bracket arms. When the arms are in the engaged position, the sensor is secured; when disengaged, the system detects this state change. This feedback mechanism ensures that removability does not compromise security, as removal attempts are detected and can trigger alarm responses.
