Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If an external energy source is used to operate the chip, then the chip can function with sufficient power, but the chip must be arranged relatively close to the external apparatus and requires physical connections or significant energy transmission
Solution Approach 1:
The patent combines the energy storage element (battery) and the integrated circuit into a single monolithic chip structure. The battery is formed in a first area of the substrate while the integrated circuit is formed in a second area, creating a self-contained unit that eliminates the need for external energy sources and physical connections, thereby resolving the contradiction between energy transmission requirements and operational independence.
2Reliability
If an external energy source is connected via wire or soldered connection, then reliable power supply is achieved, but device complexity and manufacturing complexity increase
Solution Approach 1:
The patent integrates the energy storage element directly onto the substrate in close proximity to the integrated circuit, eliminating the need for wires, soldered connections, or bond connections. This monolithic integration maintains reliable power supply while significantly reducing device complexity by removing external connection structures.
3Ease of operation
If significant energy is transmitted via electromagnetic field for chip operation, then the chip can operate without physical connections, but the transmission range is limited and energy efficiency is reduced
Solution Approach 1:
The patent creates a self-powered chip by integrating the battery with the integrated circuit on the same substrate. This eliminates the need for electromagnetic energy transmission for power supply, allowing the chip to operate independently with unlimited range while maintaining high energy efficiency, as the battery provides direct electrical power without transmission losses.
