Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic devices with liquid crystal display parts have a complex structure due to separate components, leading to increased component count, manufacturing complexity, and thickness issues, making it difficult to achieve a thin design and proper alignment of the light transmission window.
Innovation Solution
An electronic device design that integrates a design frame with a flange part and a design panel part to sandwich a light guide body, reducing the number of components and allowing for easier adjustment of the liquid crystal display panel's height, thus simplifying the structure and reducing thickness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the liquid crystal display part and the front side case are constituted by different components, then the liquid crystal display part can be separately manufactured and assembled, but the structure becomes complicated and the number of components increases
Solution Approach 1:
The patent merges the front side case and the light guide body into a single integrated component. The light guide body is formed as an integral part of the front side case, eliminating the need for separate assembly of these components. This integration maintains the manufacturing flexibility of separate production while significantly reducing structural complexity and component count.
2Ease of manufacture
If the liquid crystal display part and the front side case are separate components, then manufacturing flexibility is improved, but the thickness tolerance range becomes wider and the device thickness increases
Solution Approach 1:
By integrating the light guide body with the front side case into a single molded component, the patent eliminates the cumulative thickness tolerances that would result from assembling separate parts. This integration maintains manufacturing flexibility through injection molding capabilities while precisely controlling the overall thickness of the device.
3Ease of manufacture
If the liquid crystal display part and the front side case are separate components, then component assembly is simplified, but the height position adjustment becomes difficult and the light transmission window cannot be flush with the front side case
Solution Approach 1:
The integration of the light guide body with the front side case ensures precise positioning and alignment. The light transmission window is formed as an integral part of the molded component, guaranteeing that it is perfectly flush with the front side case surface without requiring complex adjustment mechanisms.
4Reliability
If multiple components are used including adhesive, screw, exposure prevention cushion, and electrostatic damage prevention component, then functional requirements are met, but the manufacturing process becomes complicated and product cost increases
Solution Approach 1:
The patent incorporates electrostatic discharge prevention functionality directly into the front side case through conductive material integration or surface treatment. This eliminates the need for separate electrostatic damage prevention components and their associated assembly steps, thereby improving manufacturing efficiency while maintaining ESD protection functionality.

Function Achieved in This Case
This integration results in a thinner device with reduced component count, improved manufacturing efficiency, and easier adjustment of the display panel's position, enhancing design flexibility and reducing the risk of display unevenness.
Implementation Method 1
a light guide body; a design frame which includes a flange part that protrudes inward from a peripheral edge of a frame opening... which is attached to an opening of the case to thus sandwich the light guide body between the flange part and the case
