1Length of moving object
If the thickness of the transformer is reduced to achieve slim electronic devices, then the device becomes thinner and more compact, but the strength against external pressure decreases and cracks may occur
Solution Approach 1:
The patent applies composite materials by combining the magnetic core with a protective housing structure. The housing is formed by injection-molding a resin material that encapsulates and protects the thin transformer core, providing enhanced mechanical strength and resistance to external pressure while maintaining the reduced thickness required for slim electronic devices.
2Power
If the area of the transformer is increased to maintain power output capacity in slim devices, then the power transmission capability is preserved, but the structural strength against external pressure becomes weaker
Solution Approach 1:
The protective housing formed by injection-molding creates a composite structure that distributes external pressure across the entire transformer assembly. This allows the transformer to have a larger area for maintaining power capacity while the housing provides uniform structural support, preventing the weakness that would otherwise result from the increased surface area.
Solution Approach 2:
The housing structure acts as a pre-established protective cushion that absorbs and distributes external forces before they can reach the transformer core. This beforehand protection allows the transformer to be designed with larger area for power capacity without compromising structural strength.
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 modular transformer design enhances structural integrity and flexibility, preventing cracks and ensuring reliable power delivery in slim electronic devices by increasing strength against external forces.
Implementation Method 1
The transformer uses a theory of electromagnetic induction. The transformer has a structure of a core which is wound by a pair of coils isolated from each other. For example, the number of turns of an input side coil is high while the number of turns of an output side coil is low so that when the input side coil is applied with a high voltage, the input side coil becomes an electromagnet to form a magnetic field. The magnetic field is transferred to the output side coil via the core and forms an induced current in the output side coil.
