Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge lies in providing a reliable power supply to vehicle windows that ascend and descend, as traditional wired connections risk short-circuiting and wireless solutions are excessively costly, while maintaining a simple structure.
Innovation Solution
A power supply device featuring a carrier plate with a first electrical connection, a bracket with a second electrical connection, and a flexible connection means that pivots between the two, allowing the electrical signal to be transmitted as the window moves, preventing vibration and excessive bending.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wired connection is used to supply power to the moving window, then power can be transmitted reliably, but the wire may be short-circuited or come into contact with nearby components causing noise
Solution Approach 1:
The patent uses a flexible cable with a specific geometric configuration (circular cross-section with multiple wires arranged in a hexagonal pattern) that allows the cable to bend and move with the window while maintaining electrical connection. This flexible structure prevents the wire from coming into contact with nearby components and avoids short-circuits, while still providing reliable power transmission.
Solution Approach 2:
The patent creates a dynamic electrical connection system where the cable can move and flex as the window ascends and descends. The cable is connected to the carrier plate that moves with the window, allowing the electrical connection to adapt dynamically to the window's position changes without causing short-circuits or noise.
2Object-affected harmful factors
If a wireless power supply is used, then short-circuit and noise problems are avoided, but excessively high cost is required
Solution Approach 1:
The patent replaces complex wireless power transmission systems with a simple mechanical flexible cable solution. By using a properly designed flexible cable with multiple wires in a hexagonal arrangement, the system achieves wireless-like flexibility and short-circuit prevention while maintaining the simplicity and low cost of wired electrical connections.
3Device complexity
If a rigid electrical connection is used, then structural simplicity is maintained, but the connection cannot accommodate the window's movement without causing vibration and stretching
Solution Approach 1:
The patent employs a flexible cable structure with a circular cross-section containing multiple wires arranged in a hexagonal pattern. This flexible design allows the electrical connection to accommodate the window's movement without causing vibration or stretching, while maintaining structural simplicity and reliability.
Solution Approach 2:
The patent divides the electrical connection into multiple separate wires (at least three wires) arranged in a hexagonal pattern within the flexible cable. This segmentation allows each wire to independently handle movement and stress, preventing vibration and stretching while maintaining overall connection stability and simplicity.
