Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wired electrical connection is used to power heating equipment, then electrical energy can be transmitted reliably, but user mobility is limited and electrical safety risks increase
Solution Approach 1:
The patent replaces the mechanical wired connection system with an electromagnetic induction system. The handlebars contain a transmitter coil that generates a magnetic field, which induces current in receiver coils integrated into the gloves, eliminating physical wire connections while maintaining reliable power transmission through electromagnetic coupling.
Solution Approach 2:
The patent introduces electromagnetic fields as an intermediary medium to transfer electrical energy between the handlebars and gloves. The magnetic field acts as a mediator that couples the power source in the handlebars with the heating elements in the gloves without direct electrical contact, enabling wireless power transmission.
2Reliability
If fixed hand position is required to maintain electrical connection, then contact reliability is improved, but user comfort and operational flexibility deteriorate
Solution Approach 1:
The patent transforms the static contact requirement into a dynamic system where the electromagnetic coupling automatically adjusts to hand movements. The receiver coils in the gloves and transmitter coils in the handlebars maintain functional coupling through relative motion, allowing users to move their hands freely while the system dynamically adapts the electromagnetic field distribution.
Solution Approach 2:
The patent changes the operational parameters from fixed mechanical contact to variable electromagnetic coupling. The system monitors and adjusts electrical parameters such as voltage, current, and frequency to maintain optimal power transfer efficiency despite variations in hand position, distance, or orientation between the handlebars and gloves.
3Ease of operation
If autonomous battery system is used for heating equipment, then user mobility is improved, but device complexity and energy management requirements increase
Solution Approach 1:
The patent makes the handlebars serve multiple functions: they act as both the mechanical control interface and the power transmission source. The transmitter coils integrated into the handlebars enable the same component to provide both operational control and wireless power delivery, eliminating the need for separate battery systems in the gloves.
Solution Approach 2:
The system enables the handlebars to self-provide power to the gloves through electromagnetic induction. The power transmission system automatically activates when gloves are detected near the handlebars, and the system self-regulates power distribution based on detected hand position and heating requirements, eliminating complex user management of autonomous batteries.
4Duration of action of stationary object
If continuous electrical supply is provided to gloves, then heating functionality is maintained, but electrical safety risks and energy consumption increase
Solution Approach 1:
The patent implements periodic or on-demand power transmission instead of continuous supply. The electromagnetic coupling is activated only when gloves are detected in proximity to the handlebars, and power is transmitted in controlled intervals based on detected heating requirements, reducing continuous energy consumption and electrical exposure time.
Solution Approach 2:
The system incorporates feedback mechanisms that detect hand presence, temperature requirements, and coupling efficiency to dynamically control power transmission. The transmitter adjusts or terminates power supply based on real-time feedback from sensors, ensuring heating is provided only when needed and reducing unnecessary electrical exposure and energy waste.

AI summary
The device has a handle system including two handles on which two stainless metal rings (2) are fixed, protected, controlled and supplied with current from a battery of a motorized vehicle. An electrical connection between the rings and a printed circuit board (PCB) (3) is made by a conductive insulated wire that is embedded in one of the handles. Stainless metal contacts (9) are established in internal parts of gloves, which are in contact with the rings. A magnet is placed in each glove, which permits electric power supply to each ring.
