Vehicle Seat Backrest Sockets for Heavy Accessory Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor vehicle seating arrangements struggle to securely and flexibly accommodate relatively heavy electronic devices while maintaining stability and safety during crashes.
Innovation Solution
A motor vehicle seating arrangement with vertically offset mounting sockets on the backrest allows simultaneous connection of two plug-in components, using positive and friction locking mechanisms to stabilize heavy accessories, and includes a bridge section to absorb bending moments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a single mounting socket is used to attach accessories, then the device complexity is reduced, but the stability and load-bearing capacity for heavy electronic devices is insufficient
Solution Approach 1:
The mounting system is segmented into multiple independent receiving sockets (first receiving socket and second receiving socket) distributed at different positions on the backrest. This segmentation allows the accessory to be anchored at multiple points, significantly increasing load-bearing capacity and stability while maintaining individual simplicity of each socket design.
Solution Approach 2:
The receiving sockets are arranged in a spatial distribution across the backrest surface rather than being concentrated at a single location. This spatial distribution in multiple dimensions creates a stable geometric configuration that enhances load-bearing capacity without requiring complex individual socket structures.
2Stability of the object's composition
If multiple receiving sockets are distributed across the backrest, then the stability for heavy accessories is improved, but the ease of operation for connecting accessories is reduced
Solution Approach 1:
The accessory design merges multiple plug-in parts into a single integrated structure that engages with multiple receiving sockets simultaneously. This merging allows the user to connect the accessory to multiple distributed sockets in one operation, maintaining stability while preserving ease of operation.
Solution Approach 2:
The accessory is pre-configured with multiple plug-in parts positioned and oriented to match the predetermined distribution of receiving sockets on the backrest. This preliminary arrangement ensures that when the accessory is installed, all connections are established simultaneously without requiring complex alignment or sequential connection steps.
3Device complexity
If the receiving sockets are arranged close together, then the device complexity is reduced, but the ability to absorb bending moments from heavy accessories is insufficient
Solution Approach 1:
The receiving sockets are arranged in a spatial distribution that creates favorable geometric relationships for force distribution. By positioning sockets at specific locations across the backrest, the system optimizes the moment arm distances to effectively absorb bending moments generated by heavy accessories while maintaining a simple overall design.
4Reliability
If the accessory is designed with multiple plug-in parts for different sockets, then the stability is improved, but the device complexity of the accessory increases
Solution Approach 1:
Multiple plug-in parts are merged into an integrated accessory structure where the individual connection elements are combined into a unified design. This merging achieves reliable multi-point attachment while avoiding the complexity of separate, independently operated connection mechanisms.
Solution Approach 2:
The plug-in parts are designed with universal characteristics that allow them to engage with different receiving socket types or positions. This universality enables a single accessory design to reliably connect to multiple sockets without requiring complex, specialized connection elements for each socket.
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
The arrangement provides a stable and secure attachment for heavy electronic devices, ensuring they remain undamaged during crashes and enabling flexible use of various accessories.
Implementation Method 1
the locking device can be exclusively positive-locking, for example, via interlocking surfaces that interact with each other as an undercut
Implementation Method 2
The aforementioned locking devices can also be both positive-locking and friction-locking, for example, via wedge surfaces in contact with each other
Implementation Method 3
The distance between the two mounting sockets helps to better absorb bending moments caused by the weight of the accessory via the plug parts and in the mounting sockets
