Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If metal screws and nuts are used for screw connection, then mounting reliability is improved, but conductive leakage paths form leading to safety hazards
Solution Approach 1:
The patent introduces an insulating component as an intermediary element in the screw connection structure. This insulating component is positioned between the metal screw and the electrical structure, allowing the metal screw to maintain its fastening function while preventing direct conductive contact with the electrical structure, thus blocking leakage paths.
Solution Approach 2:
The screw connection structure is segmented into multiple functional components: the metal screw for mechanical fastening, the insulating component for electrical isolation, and the limiting member for positioning. This segmentation allows each component to perform its specific function without interfering with others, resolving the contradiction between mechanical reliability and electrical safety.
2Object-affected harmful factors
If insulating screws and nuts are used to prevent conductive leakage, then safety is improved, but mounting reliability deteriorates
Solution Approach 1:
The patent merges the functions of multiple components into an integrated assembly: the metal screw provides mechanical strength and fastening reliability, while the insulating component integrated into the connection structure provides electrical isolation. This combination achieves both mounting reliability and safety simultaneously.
Solution Approach 2:
The connection structure uses composite material design, combining metallic materials for mechanical fastening with insulating materials for electrical isolation. This composite approach allows the same connection assembly to provide both mechanical reliability and electrical safety without compromise.
3Object-affected harmful factors
If grounding apparatus is added to ensure grounding, then safety is improved, but device complexity increases
Solution Approach 1:
The insulating component and limiting member are integrated into the existing screw connection structure, allowing the connection assembly to simultaneously perform mechanical fastening and electrical isolation functions without requiring separate grounding apparatus. The structure serves multiple functions through its own components.
Solution Approach 2:
The screw connection structure is designed with multi-functionality: the metal screw provides mechanical fastening, the insulating component provides electrical isolation, and the limiting member provides positioning. This universal design eliminates the need for additional dedicated grounding components.
4Object-affected harmful factors
If insulating seat and limiting member are added, then conductive leakage is prevented, but device complexity increases
Solution Approach 1:
The insulating component and limiting member are nested within the screw connection structure. The insulating component is positioned within the connection assembly, and the limiting member is integrated into the insulating seat, creating a compact nested arrangement that prevents leakage without significantly increasing overall device complexity.

AI summary
A fixing connection assembly, an electronic device, and an electric power system are provided, which relate to the technical field of electrical technology. In the fixing connection assembly, a limiting structure includes an insulating seat and a limiting member, and the insulating seat is provided with an accommodation cavity and a first hole in communication with the accommodation cavity. The limiting member is accommodated inside the accommodation cavity. The insulating seat is configured to be arranged at a second hole of an electrical structure. A first connector is configured to pass through a third hole of a to-be-connected structure, the second hole, and the first hole. One end of the first connector is connected to the limiting member, and the other end of the first connector is connected to the to-be-connected structure at the third hole, such that a position of the electrical structure relative to a position of the to-be-connected structure is fixed. The to-be-connected structure includes a first housing, and the electrical structure is located inside a mounting cavity of the first housing. At least an inner surface of the first housing is insulated from the electrical structure. The electrical structure and the to-be-connected structure can be reliably connected to each other, and a leakage conductive path of the electrical structure formed by a fixing connection structure can be avoided, thereby reducing safety hazards.
