Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If demonstration models are made accessible for testing and operation, then customer examination capability is improved, but vulnerability to theft increases
Solution Approach 1:
The security system divides the demonstration model into separate components: a display portion and a base portion, connected by a cable. This segmentation allows the model to be accessible for examination while the security infrastructure remains in place to prevent theft.
Solution Approach 2:
A cable acts as an intermediary element connecting the demonstration model to the base/security system. This intermediary maintains the security connection while allowing the model to be moved and handled by customers for examination.
2Reliability
If physical security measures are implemented to prevent theft, then security is improved, but customer ability to examine and operate the product deteriorates
Solution Approach 1:
The security connection is localized to specific points: the cable connection point on the demonstration model and the corresponding connection point on the base. This localized security approach allows the rest of the model to remain fully accessible for customer examination and operation.
Solution Approach 2:
The patent replaces traditional mechanical security systems (such as locks or fixed mounting) with an optical sensing system. The sense loop uses optical detection rather than mechanical constraints, allowing customers to freely handle the model while security is maintained through non-mechanical means.
3Reliability
If a security cable is used to prevent removal, then theft prevention is improved, but the system complexity increases
Solution Approach 1:
The patent extracts the security sensing function from the cable itself, creating a separate sense loop that is electrically isolated from the power and data communication circuits. This extraction simplifies the overall system by separating security functions from other functions, making each component more straightforward to design and implement.
