Vehicle Holder Device Sliding on Power Supply Rail
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing holder devices for mobile devices in vehicles are difficult to move and reposition without causing damage to the air outlet and expose power lines, leading to aesthetic and safety issues.
Innovation Solution
A holder device for a power supply rail with a main body part that is slidably movable within the rail, featuring a rotatable head part that fixes the sliding position using lock anchors and a fixing member that protrudes to secure the position, allowing for easy repositioning and hiding power connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a holder is mounted on a vehicle air outlet and fixed thereto, then the mobile device can be securely held, but damage to the air outlet may occur due to the weight of the mobile device
Solution Approach 1:
The patent introduces a power supply rail as an intermediary structure between the holder and the vehicle air outlet. The holder is mounted on the power supply rail instead of directly on the air outlet, distributing the weight and preventing damage to the air outlet while maintaining secure holding capability
Solution Approach 2:
The system is segmented into separate functional components: the power supply rail mounted on the air outlet, and the holder mounted on the power supply rail. This segmentation allows the holder to be independently positioned and secured without directly impacting the air outlet structure
2Reliability
If a holder is fixed to the air outlet, then the mobile device can be held securely, but when a user wants to move the location of the mobile device, the holder is required to be removed and re-mounted, which causes inconvenience
Solution Approach 1:
The holder is designed to be dynamically repositionable along the power supply rail. The power rail includes multiple positioning holes at different locations, allowing the holder to be easily moved to different positions and secured at each position without removal and re-mounting
Solution Approach 2:
The power supply rail is segmented with multiple discrete positioning holes, enabling the holder to be positioned at various locations along the rail. This segmentation provides flexible repositioning capability while maintaining secure attachment at each position
3Ease of manufacture
If a power line is separately connected to the mobile device for recharging, then the mobile device can be recharged, but it may spoil the aesthetics of the interior of the vehicle and expose users to electric shock risk
Solution Approach 1:
The power supply rail combines both mechanical support and electrical power supply functions into a single integrated structure. The holder mounted on the rail receives both physical support and electrical power through the same mounting interface, eliminating the need for separate power lines
Solution Approach 2:
The power supply rail serves multiple functions simultaneously: it provides mechanical support for the holder, enables repositioning along the rail, and supplies electrical power for recharging the mobile device. This multi-functionality eliminates the need for separate power connections
