Charging Station Cantilever Arm for Flexible Cable Reach
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing charging stations have limited cable lengths that restrict vehicle parking flexibility and require complex, force-exerting folding mechanisms for cable connection, leading to user inconvenience and potential cable damage.
Innovation Solution
A cantilever device with a rigid beam and modular fastening system allows for flexible cable guidance and extension, enabling convenient cable management and increased parking options, while eliminating the need for complex folding devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the charging cable length is limited to prevent it from touching the ground, then the cable is protected from being soiled and damaged, but the radius of action of the charging station is restricted
Solution Approach 1:
The patent introduces a spatial dimension by elevating the cable above the ground using a support structure. The cable is suspended in the air between the charging station and the vehicle, transforming the cable management from a ground-level constraint to an aerial pathway, thereby extending the effective cable length without ground contact
Solution Approach 2:
The patent employs an intermediary support structure (such as a pole or arm) that acts as a mediator between the charging station and the vehicle. This intermediary carries the cable aloft, allowing the cable to reach farther while maintaining protection from ground contact through the intermediary's elevation function
2Adaptability or versatility
If a folding device with restoring force is used to pivot the charging arm, then the charging arm can be positioned flexibly, but the user has to expend force and the restoring force exerts tensile force on the charging cable
Solution Approach 1:
The patent removes the folding device with restoring force from the charging arm mechanism. By extracting this complex mechanism, the design simplifies to a fixed or manually adjustable arm without automatic restoring forces, eliminating the need for users to overcome spring tension while maintaining positioning flexibility through simpler means
3Adaptability or versatility
If the charging arm is designed with a folding device, then the charging station can adapt to different positions, but the device complexity increases
Solution Approach 1:
The patent extracts and removes the folding device from the charging arm design. This elimination of the complex folding mechanism with multiple joints and restoring springs significantly reduces device complexity while maintaining the essential functionality of positioning the charging cable to reach the vehicle
