Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electromagnetic waves generated by electronic or electrical apparatuses can interfere with signal processing systems, leading to malfunction and performance degradation, and may also pose health risks. Existing shielding solutions may not adequately address these issues.
Innovation Solution
A shielding cover comprising a shielding cover body and a shielding cover accessory, which includes a flat bottom, connecting and positioning arms, card slots, and openings, is designed to be fixedly connected to the shielding cover body. This configuration enhances electromagnetic wave shielding and provides structural support for the display device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a shielding cover is used to reduce electromagnetic radiation, then electromagnetic interference is reduced, but the device structure becomes more complex
Solution Approach 1:
The shielding cover is divided into a body portion and an accessory portion, which can be separately manufactured and then assembled. The accessory portion includes a connecting arm and a positioning arm that can be independently formed and attached to the body portion, simplifying the overall manufacturing process while maintaining shielding effectiveness.
Solution Approach 2:
The accessory portion is designed to be nested within or attached to the body portion of the shielding cover. The connecting arm and positioning arm are integrated into the overall structure in a space-efficient manner, reducing the total volume occupied while providing the necessary shielding functions.
2Ease of manufacture
If multiple components are used to form the shielding cover, then manufacturing flexibility is improved, but assembly complexity increases
Solution Approach 1:
The connecting arm and positioning arm are combined into a single accessory portion that can be manufactured as one integrated component. This accessory portion is then attached to the body portion through a simplified process using the card slots and limiting portions, reducing assembly steps while maintaining manufacturing flexibility.
Solution Approach 2:
The accessory portion includes self-aligning features such as card slots with limiting portions that guide the assembly process. The limiting portions automatically constrain the positioning of the accessory relative to the body, eliminating the need for complex alignment procedures or additional fastening steps.
3Manufacturing precision
If the shielding cover accessory includes multiple structural elements, then positioning accuracy is improved, but the number of parts increases
Solution Approach 1:
The connecting arm and positioning arm are merged into a single accessory portion, reducing the total number of parts. The accessory portion includes integrated features such as card slots with limiting portions that provide both connection and positioning functions in one component.
Solution Approach 2:
The accessory portion serves multiple functions: it connects the shielding cover to the display device, positions the shielding cover accurately, and provides structural support. The card slots with limiting portions provide both attachment and positioning capabilities, eliminating the need for separate positioning components.

AI summary
A shielding cover and a display device are provided. The shielding cover includes: a shielding cover body; and a shielding cover accessory fixedly connected to the shielding cover body. The shielding cover accessory includes: an accessory bottom including a flat bottom; a connecting arm through which the shielding cover accessory is connected to the shielding cover body; and a positioning arm. The connecting arm and the positioning arm are connected to two opposite ends of the accessory bottom, and protrude in opposite directions from the accessory bottom. The shielding cover accessory further includes a plurality of card slots arranged at positions of the flat bottom close to the positioning arm, each card slot penetrates the flat bottom in a direction perpendicular to the flat bottom, and the plurality of card slots are arranged at intervals in a direction parallel to an extending direction of the positioning arm.
