Innovation Solution
A display device with integrated circuits on a single-layer structure powered by a composite laminated structural battery, eliminating the need for manual cable installation and allowing autonomous operation, featuring a flexible polymer film with printed conductors and LEDs, and a modular battery design for easy adaptation and connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional cable harness connections and multi-part assemblies are used, then reliable power supply and data connection are achieved, but manufacturing complexity and assembly time increase significantly
Solution Approach 1:
The patent combines power supply, data transmission, and control functions into an integrated display module with built-in battery and circuit board. This merging eliminates the need for separate cable harness connections while maintaining reliable power and data transmission, directly resolving the contradiction between connection reliability and assembly complexity
Solution Approach 2:
The display module is designed as a universal self-contained unit that integrates multiple functions (display, power supply, data processing, control) into a single module. This multi-functionality allows the module to operate independently without complex external wiring, reducing assembly time while ensuring reliable operation
2Productivity
If standardized display modules with integrated circuits are used, then assembly time and manufacturing effort are reduced, but power supply reliability in emergency situations may be compromised
Solution Approach 1:
The display module is pre-equipped with an integrated battery and power management circuitry during manufacturing. This preliminary action ensures that power supply capability is built-in before installation, allowing rapid deployment while guaranteeing emergency operation without requiring complex external power connections
Solution Approach 2:
The display module is designed as a self-contained unit with integrated power supply (battery), control circuitry, and display elements. This self-service design enables the module to operate independently without requiring external power connections or complex wiring, thus reducing assembly time while ensuring reliable emergency operation
