Power Supply Wire Securing Structure for Vibration-Safe Clearance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge of ensuring a safe distance between wires and other elements in compact power supplies, where flexible wires can deform or displace, violating safety requirements, and existing solutions either fail to maintain this distance or increase cost and complexity.
Innovation Solution
A wire securing assembly with an insulating part featuring a base plate and securing structures, such as parallel or curved plates, restricts wire movement within a defined space, preventing contact with other components while adhering to safety standards without additional cost or space occupation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If additional fixtures or fixing poles are mounted in the housing to secure the wire, then the wire displacement is restricted, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent combines the wire securing function with the existing insulating part structure. The insulating part is extended to form a securing structure that includes a first plate and a second plate, integrating wire restraint into the insulating component rather than adding separate fixtures or fixing poles.
Solution Approach 2:
The insulating part is designed to serve multiple functions: it provides electrical insulation between the circuit board and housing, and simultaneously acts as a wire securing structure through its extended plates that constrain wire movement within the housing.
2Stability of the object's composition
If additional fixtures or fixing poles are mounted in the housing to secure the wire, then the wire displacement is restricted, but the housing space is occupied
Solution Approach 1:
The wire securing function is merged with the insulating part structure. The first plate and second plate are extensions of the insulating part itself, eliminating the need for separate space-consuming fixtures or fixing poles in the housing.
Solution Approach 2:
The insulating part serves dual purposes: providing electrical insulation and securing the wire through its extended plate structure, thereby achieving wire stabilization without dedicating additional housing space to separate securing components.
3Ease of operation
If the wire is allowed to be flexible for easy installation, then the installation ease is improved, but the wire may deform or displace after installation, violating safety requirements
Solution Approach 1:
The insulating part is designed with extended plates that create a predetermined securing structure before wire installation. The first plate and second plate are positioned to define a specific space that guides and constrains the wire during installation and maintains its position afterward, ensuring safety distance is preserved.
Solution Approach 2:
The insulating part with its extended plates acts as an intermediary structure between the wire and the housing. It provides a controlled environment that allows the wire to be flexible during installation while preventing displacement afterward, thus mediating between installation ease and safety reliability.

AI summary
A power supply has a housing, a circuit board, a wire, and a wire securing assembly. The wire securing assembly has a base plate and a securing structure. The securing structure has a first plate and a second plate. A side edge of the first plate is connected to the base plate. The second plate is spaced apart from the first plate. The wire is mounted through and between the first plate and the second plate. The wire securing assembly is modified from the current insulating part, in which the original side plate extends and forms an additional part, or a bent structure is added on the original side plate, and thus the additional structures become the securing structure. Thus, the wire is prevented from moving under vibration or external force and contacting the blades of the fan, or keeps in a position in compliance with safety requirements.
