Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle outlet apparatuses restrict the use of multiple electrical appliances due to fixed positions and limited plug connections, causing user discomfort and inconvenience, especially when using appliances with short power cables.
Innovation Solution
A vehicle outlet apparatus with a detachable multitap and automatic cable winding mechanism, allowing multiple appliances to be used simultaneously and ensuring cable neatness without external exposure, featuring a magnetic attachment system and elastic member for easy extension and retraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed indoor V2L outlet apparatus is used, then the outlet position is stable and easy to install, but the user position is restricted and uncomfortable when using appliances with short power cables
Solution Approach 1:
The patent applies the dynamics principle by making the outlet body detachable from the vehicle interior panel. The outlet body can be removed and repositioned to different locations within the vehicle, transforming the fixed outlet into a movable one. This allows users to flexibly position the outlet near electrical appliances regardless of the original fixed position, solving the contradiction between stable installation and user position flexibility.
2Adaptability or versatility
If only one or two plugs are connected to the outlet apparatus, then the outlet structure remains simple, but additional multitap devices are required when multiple electrical appliances need to be used
Solution Approach 1:
The patent applies the universality principle by designing the outlet body to include multiple sockets that can accommodate various plug types. The outlet body is configured to simultaneously receive and power multiple electrical appliances with different plug specifications. This integrated multi-functional design eliminates the need for separate multitap devices, allowing users to directly connect multiple appliances to the outlet body, thereby solving the contradiction between multi-appliance usage capability and device complexity.
3Ease of operation
If the cable is extended outside the vehicle for appliance usage, then power supply flexibility is improved, but the cable requires additional arrangement and storage space
Solution Approach 1:
The patent applies the nested doll principle by providing a cable storage chamber within the outlet body that can accommodate the power cable. When not in use, the cable can be retracted and stored inside the outlet body, which itself can be stored within the vehicle interior panel. This nested storage structure eliminates the need for separate cable management systems and additional storage space, allowing the cable to be neatly contained within the integrated outlet assembly, thereby solving the contradiction between cable management convenience and cable storage space.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables convenient and simultaneous use of multiple electrical appliances with flexible cable management, eliminating the need for additional storage arrangements and maintaining a tidy exterior.
Implementation Method 1
the cable is mechanically connected to an elastic member and may be wound around the elastic member, and the elastic member may provide a rotational elastic force in a direction in which the cable is wound around the elastic member
Implementation Method 2
The multitap and the seating receptacle may be configured to provide a magnetic attraction force that attaches the multitap to the seating receptacle
