Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless power transmission and contactless data communication are used, then reliability is improved by eliminating wear and corrosion from physical connections, but device complexity increases due to the need for inductive coils or optical components
Solution Approach 1:
The patent replaces mechanical electrical connections (plugs and sockets) with inductive power transmission and contactless optical communication. This substitution eliminates physical contact between mating components, thereby eliminating wear, corrosion, and connection reliability issues while accepting increased internal complexity through coils and optical components.
2Ease of operation
If the control panel is made removable for ease of operation and maintenance, then ease of operation is improved, but reliability deteriorates due to wear on contact parts and corrosion from environmental exposure
Solution Approach 1:
The patent enables the control panel to be removable and replaceable while eliminating wear and corrosion issues by substituting mechanical electrical connections with inductive power transmission and contactless optical communication. The wireless interface allows the panel to be easily removed and replaced without degrading connection reliability over time.
3Device complexity
If traditional plugs and sockets are used for power and data connections, then device complexity is reduced, but reliability deteriorates due to wear on contact parts and corrosion from humidity and environmental conditions
Solution Approach 1:
The patent replaces traditional mechanical plugs and sockets with inductive power transmission coils and contactless optical communication components. This substitution eliminates the wear and corrosion problems inherent in mechanical contact systems, significantly improving connection reliability despite the increased internal complexity of the wireless interface components.
4Reliability
If the control panel is sealed to protect against environmental conditions, then reliability is improved by preventing corrosion and wear, but ease of operation deteriorates due to the need for lids and removal mechanisms
Solution Approach 1:
The patent eliminates the need for seals, lids, and complex removal mechanisms by implementing wireless inductive power transmission and contactless optical communication. The control panel can be simply placed in or removed from the receptacle without any connection operations, achieving both environmental protection and ease of operation.

Implementation Method 1
the operating power is transmitted inductively by a transmitting coil in a receptable for the control panel to a receiving coil inside the control panel
Implementation Method 2
A line of light emitting diodes (LEDs) may be fitted in bottom or the sides of the receptable and corresponding sensors may be lined up in the bottom or on the sides of the control panel
Implementation Method 3
corresponding sensors may be lined up in the bottom or on the sides of the control panel

AI summary
Earth moving equipment and other heavy machinery for environmentally harsh conditions are controlled by a control panel supplied with a lock, and such panels are frequently removable to prevent theft or unauthorized operation. The interface is in the form of a plug-and-socket, the parts of which have to be sealed against dust and humidity when not interfacing. In order to prevent wear and to assure reliable control, according to the invention, no part of the connection between the control panel and a receptable is galvanic, the power supply for the control panel is wireless, such as inductive or optical, while communications may occur by means of a two-way radio protocol or by optical means.
