Flat Panel Display Motherboard Integration for Assembly Simplification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly and production of conventional Liquid Crystal Display televisions are complex and costly due to the need for multiple circuit boards and cables to connect press buttons, infrared receivers, and light-emitting diodes to the motherboard.
Innovation Solution
Integrating press buttons, a wireless signal receiver, and light-emitting diodes directly onto the motherboard, eliminating the need for separate circuit boards and cables by using light guides that extend into holes in the front frame to position these components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate circuit boards and cables are used to connect press buttons, infrared receiver, and light-emitting diodes to the motherboard, then the functionalities are achieved, but the assembly complexity and production cost increase
Solution Approach 1:
The patent merges the press buttons, infrared receiver, and light-emitting diodes onto a single motherboard, eliminating the need for separate circuit boards and cables. This integration reduces the number of components and simplifies the assembly process while maintaining all required functionalities.
Solution Approach 2:
The motherboard is designed to perform multiple functions by integrating diverse components (press buttons for input, infrared receiver for signal reception, and light-emitting diodes for indication) onto a single platform, making it a universal control and display interface.
2Adaptability or versatility
If separate circuit boards and cables are used to connect press buttons, infrared receiver, and light-emitting diodes to the motherboard, then the functionalities are achieved, but the production cost increases
Solution Approach 1:
By combining multiple components onto a single motherboard, the patent reduces the total number of parts that need to be manufactured, stored, and assembled. This consolidation directly lowers production costs by eliminating redundant circuit boards and cable connections.
3Reliability
If plug electrical connectors are connected to slot electrical connectors for assembling press button module and status indicating module, then electrical connection is achieved, but assembly time and labor increase
Solution Approach 1:
The patent integrates all electrical connections directly into the motherboard structure, eliminating the need for separate plug connectors and slot connectors. This direct integration maintains reliable electrical connections while significantly reducing assembly time and labor requirements.
