Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the terminal is simply inserted into a base with clips, then the terminal is easily removable for customer use, but the terminal becomes susceptible to theft and unauthorized removal

Engineering Contradiction:
Improveease of removalVSAvoidsecurity against theft
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent replaces the purely mechanical clip-based locking system with an electromechanical system. The base includes an electromechanical actuator that can actively engage and disengage locking elements, transforming the passive mechanical connection into an active controlled system. This allows the terminal to be securely locked during transport while enabling easy authorized removal through electronic control signals.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The terminal itself serves as the control mechanism for unlocking. When the terminal is properly inserted into the base, it automatically triggers the unlocking sequence through its presence and communication capabilities, eliminating the need for external manual intervention. The terminal's own operational state (power on, communication established) becomes the key to unlocking, making the system self-serve its security function.

Inventive Principle:
Principle #25Self-service

2Reliability

If a locking system is implemented to prevent unauthorized removal, then security against theft is improved, but the system becomes more complex and costly

Engineering Contradiction:
Improvesecurity against theftVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The base unit is designed to serve multiple functions: it provides mechanical support for the terminal, houses the electromechanical actuator for secure locking, and incorporates control electronics for monitoring and unlocking. This multi-functional design consolidates what could be separate complex systems into a single integrated base, reducing overall system complexity while maintaining security functionality.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent introduces a control signal as an intermediary between the user's intent to remove the terminal and the actual mechanical unlocking action. Rather than direct manual manipulation of mechanical locks, the system uses electronic control signals mediated through the terminal's communication interface to trigger the electromechanical actuator, simplifying the user interaction while maintaining security control.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If a locking system is implemented to prevent unauthorized removal, then security against theft is improved, but the cost of the system increases significantly

Engineering Contradiction:
Improvesecurity against theftVSAvoidmanufacturing cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent changes the operational parameters of the locking system by using low-power electromechanical actuators that consume minimal energy and can be controlled through simple digital signals. The actuator operates in discrete states (locked/unlocked) rather than requiring continuous control, and the unlocking trigger is based on the terminal's operational status rather than complex authentication sequences, reducing the cost of control electronics and actuators.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent merges the security locking function with the existing base structure that provides mechanical support. Rather than adding a separate locking mechanism to an existing simple base, the design integrates the electromechanical actuator and control electronics directly into the base unit, combining structural support and security functions in a single manufactured component, thereby reducing overall system cost.

Inventive Principle:
Principle #5Merging (Combining)

4Reliability

If the terminal is securely locked to the support, then theft is prevented, but the terminal cannot be easily removed for transaction use

Engineering Contradiction:
Improvesecurity against theftVSAvoidtime for removal
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary actions by pre-establishing the communication link and authentication protocol between the terminal and base before the actual removal action is needed. When the terminal is inserted, the base immediately begins monitoring its operational status and prepares the unlocking sequence. This preliminary setup ensures that when removal is authorized, the unlocking action can execute immediately without delay for authentication or system preparation.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The locking system transitions from a static locked state to a dynamic controllable state. The electromechanical actuator can rapidly switch between locked and unlocked positions in response to control signals, and the control system dynamically adjusts the locking state based on the terminal's operational status. This dynamic behavior allows the system to maintain security during transport while enabling rapid transitions to an unlocked state for transaction use.

Inventive Principle:
Principle #15Dynamics
