Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Laminated assemblies with functional elements pose safety hazards due to electric shock sensations when the second functional layer accumulates charges during use.
Innovation Solution
Incorporating a charge lead-out member and/or electromagnetic field shielding member in the laminated assembly to reduce charge accumulation on the second functional layer, which is grounded to prevent electric shocks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If electric current is applied to functional elements to enable lighting, privacy, video and heating functions, then the laminated assembly achieves functionalization, but charge accumulation on the surface causes electric shock sensation and safety hazards
Solution Approach 1:
A charge lead-out member is introduced as an intermediary component between the second functional layer and ground. This member provides a dedicated pathway for accumulated charges to flow to ground, preventing charge buildup on the surface that causes electric shock sensation, while maintaining the functional elements' operation
Solution Approach 2:
The harmful effect of charge accumulation is extracted and redirected by connecting the second functional layer to ground through the charge lead-out member. This separates the functional operation from the charge accumulation problem, allowing functions to operate while charges are continuously drained to ground
2Reliability
If a charge lead-out member is added to conduct away charges and eliminate electric shock sensation, then safety is improved, but device complexity increases
Solution Approach 1:
The charge lead-out member is designed to serve multiple functions: it provides electrical connection to ground for charge drainage, and simultaneously acts as a structural support element within the laminated assembly. This multi-functionality reduces the need for separate components, thereby limiting the increase in device complexity
Solution Approach 2:
The charge lead-out function is merged with existing structural elements or mounting components of the laminated assembly. By combining the charge drainage function with structural support or mounting features, the patent avoids adding separate dedicated components, thus minimizing complexity increase

AI summary
Provided are a laminated assembly (1000), a connector structure (32) for the laminated assembly (1000), and a vehicle. The laminated assembly (1000) comprises a laminated body (100), the laminated body (100) comprising at least one of a first transparent substrate (50), a second transparent substrate (60), a first functional layer (10), a second functional layer (20), a charge lead-out member (30) and an electromagnetic-field shielding member (40), wherein the first functional layer (10) is used for being electrically connected to an external power source; the second functional layer (20) is provided on the side of the second transparent substrate (60) that faces away from the first functional layer (10); the charge lead-out member (30) is provided on the side of the second functional layer (20) that faces away from the second transparent substrate (60), one end of the charge lead-out member (30) is electrically connected to the first functional layer (10), and the other end thereof is used for grounding; and the electromagnetic-field shielding member (40) is provided between the first functional layer (10) and the second functional layer (20), or the electromagnetic-field shielding member (40) is provided on the side of the second functional layer (20) that faces away from the second transparent substrate (60); or the laminated body (100) further comprising a second shielding layer (80), wherein the second shielding layer (80) is arranged along the periphery of the laminated body (100), and one end of the charge lead-out member (30) is at least electrically connected to part of the second shielding layer (80), and the other end of the charge lead-out member (30) is used for grounding. Since the charge lead-out member (30) is used, the usage safety of the laminated assembly (1000) can be improved. Since the second shielding layer (80) is used, the mounting effect of the laminated assembly (1000) can be beautified, and some ultraviolet rays can also be shielded, such that the impact of direct ultraviolet radiation on the charge lead-out member (30) is reduced.
