Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle rear seat frames lack adjustment functions and are prone to accidental triggering of flipping, which affects space utilization and riding comfort, and poses safety risks due to operational errors.
Innovation Solution
A vehicle rear seat frame with a sliding adjustment assembly and flipping assembly, equipped with a bidirectional assist mechanism, anti-misoperation assembly, and unlocking driving assembly, allowing for controlled sliding and flipping operations, preventing accidental triggering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the rear seat frame is fixedly installed without adjustment function, then the structure is simple and stable, but the space utilization and riding comfort are reduced
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed rear seat frame into a movable one with sliding and flipping capabilities. The seat frame body is connected to the vehicle body through sliding adjustment assemblies that enable front-rear movement, and flipping assemblies that allow the seat to rotate into a storage recess, providing dynamic adaptability for different space requirements.
Solution Approach 2:
The patent segments the seat frame system into multiple independent components: the seat frame body, sliding adjustment assemblies at the front and rear, flipping assemblies with rotating shafts, and locking mechanisms. This segmentation allows each component to perform its specific function independently while contributing to the overall adjustability and space-saving capability.
2Adaptability or versatility
If the rear seat frame is equipped with flipping function, then the space utilization is improved, but accidental triggering due to operational errors occurs
Solution Approach 1:
The patent implements preliminary anti-action by designing an anti-misoperation assembly that proactively prevents accidental triggering. This assembly includes a locking mechanism that must be deliberately activated through specific operations (sliding to the end position and pulling the handle) to enable flipping, thereby blocking unintended activation before it can occur.
Solution Approach 2:
The patent applies preliminary action by requiring the seat to first slide to a specific end position before the flipping function can be activated. The sliding adjustment assembly must be moved to its limit position, triggering a mechanism that then allows the flipping assembly to be activated, ensuring that flipping only occurs under controlled conditions.
3Ease of operation
If the sliding and flipping operations are made easy to operate, then the ease of operation is improved, but the risk of accidental triggering increases
Solution Approach 1:
The patent requires the user to first slide the seat to the end position as a preliminary action before the flipping function becomes accessible. This multi-step process ensures deliberate operation while maintaining ease of use through simple sliding and handle-pulling actions that are intuitively understood by users.
Solution Approach 2:
The patent introduces an intermediary mechanism (the locking assembly with handle and cable) that mediates between the user's action and the flipping operation. The handle acts as an intermediary control that must be pulled to unlock the flipping mechanism, providing a clear and deliberate user action that reduces accidental triggering while maintaining operational simplicity.
