Shielding Device With Intermediary Elements Blocking Wave Leakage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional shielding devices allow electric waves to enter and leak through gaps, interfering with communication and potentially harming human health.
Innovation Solution
The shielding device incorporates shielding elements on the upper cover that block clearances when closed over the lower frame, using recesses and protrusions for a tight connection to prevent wave entry and leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If clearances are left between adjacent sidewalls for assembly ease, then ease of manufacture is improved, but shielding effectiveness deteriorates due to electric wave leakage
Solution Approach 1:
A shielding element is introduced as an intermediary component between the upper cover and lower frame. This element fills the clearance gap that exists when the cover is closed onto the frame, blocking electric waves from passing through the gap while allowing the clear assembly structure to be maintained.
Solution Approach 2:
The shielding element is strategically placed only at specific locations where clearances exist between adjacent sidewalls. This localized approach provides shielding effectiveness precisely where needed without requiring complete redesign of the entire structure, maintaining ease of manufacture while addressing the leakage problem.
2Object-affected harmful factors
If a tight seal is achieved to block electric waves, then shielding effectiveness is improved, but device complexity increases
Solution Approach 1:
The shielding function is segmented from the main structural components. Instead of making the entire upper cover or lower frame complex, the shielding function is separated into a distinct, simple shielding element that can be independently designed and positioned, reducing overall device complexity while achieving the tight seal effect.
Solution Approach 2:
The shielding element serves as a simple intermediary component that achieves the tight seal for blocking electric waves without requiring complex modifications to the existing upper cover and lower frame structures. This mediator approach maintains structural simplicity while improving shielding effectiveness.

AI summary
A shielding device includes an upper cover and a lower frame. The upper cover is formed at predetermined positions with a plurality of shielding elements. When the upper cover is closed onto the lower frame, the shielding elements block clearances on the upper cover to effectively stop electric waves from entering into and leaking from the shielding device via the clearances on the upper cover.
