Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple functions (key, starter, selector switch) are integrated into a single remote control, then ergonomics and customization capability are improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent combines multiple functions (authorization key, starter button, selector switch with 1-5 positions) into a single integrated remote control device. The identifier device serves simultaneously as the authorization key and the operational control interface, eliminating the need for separate mechanical components and reducing overall device complexity despite the multifunctional capability.
Solution Approach 2:
The remote control is designed as a universal device that can perform multiple functions: authorization verification via RFID, starter button activation, and selector switch operations with customizable positions (1-5). This multi-functional design improves ergonomics by reducing the number of separate devices the operator must handle while maintaining full operational capability.
2Reliability
If RFID key system with 64-bit identifier and memory is incorporated, then security and customization capability are improved, but device complexity and cost increase
Solution Approach 1:
The patent replaces traditional mechanical key systems with an RFID-based electronic identification system. The 64-bit unique identifier and memory storage provide advanced security and customization capabilities without requiring complex mechanical structures. The RFID reader and sensor system electronically verifies authorization, eliminating the need for physical key mechanisms while enhancing security.
3Adaptability or versatility
If two 3D Hall effect sensors and RFID reader are incorporated, then functionality and security are improved, but manufacturing cost increases
Solution Approach 1:
The identifier device serves multiple functions simultaneously: it acts as the authorization key via RFID, provides selector switch functionality through magnetic field interaction with Hall effect sensors, and enables starter button operation. This multi-functionality reduces the need for separate components and justifies the integration cost by eliminating other mechanical parts.
Solution Approach 2:
The patent uses magnetic field interaction as an intermediary mechanism between the identifier device and the selector switch function. The magnet within the identifier device interacts with the 3D Hall effect sensors to detect rotational position, providing a contactless and wear-free method for position detection that simplifies the overall mechanical structure.
4Ease of operation
If compact design with reduced dimensions is implemented, then ergonomics are improved, but space for components is reduced
Solution Approach 1:
The patent implements a nested structure where the RFID reader, Hall effect sensors, and magnet are integrated within the identifier device itself or in close proximity. The identifier device becomes the central hub containing or housing the authorization and control functions, allowing the remote control to maintain a compact form factor while accommodating all necessary components.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enables a single, low-cost, compact remote control that effectively integrates key, starter, and optional selector switch functions, providing high security and customization options while maintaining robustness and ergonomic usability in industrial settings.
Implementation Method 1
The possibility of the RFID key using a reader inside the casing of the remote control is contemplated. This reader can be communicated with an RFID identification tag located in the key located in the outer portion of the casing.
Implementation Method 2
incorporating two three-dimensional Hall effect sensors inside the casing of the remote control. One of said sensors is responsible for measuring the interference magnetic field reference, while the other sensor measures the magnetic field of a magnet housed in the multifunction identifier device
