Vehicle Seat Holding Layout for Stable Body Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing seat holding apparatuses for vehicle manufacturing struggle to reliably hold seats with varying specifications in an automatic assembly line, often resulting in instability and interference with vehicle body components during insertion.
Innovation Solution
A seat holding apparatus comprising a base with a clamp, a rotatably mounted back push unit, and a linearly movable cushion push unit, driven by respective drive mechanisms, which securely engage the seat back and cushion to maintain stability and prevent interference with vehicle body holes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a seat holding apparatus is designed to hold seats with varying specifications, then the reliability of seat holding is improved, but the device complexity increases
Solution Approach 1:
The seat holding apparatus is divided into distinct functional modules: a clamp unit for gripping the seat back, a cushion push unit for supporting the seat cushion, and a back push unit for positioning the seat back. Each module can independently adjust to accommodate different seat specifications, thereby maintaining high reliability while managing device complexity through modular design
Solution Approach 2:
The apparatus incorporates movable and adjustable components including the rotatable back push unit and the linearly movable cushion push unit. These dynamic elements allow the apparatus to adapt its configuration to match various seat dimensions and specifications, enabling reliable holding of diverse seats without requiring a completely different apparatus for each seat type
2Volume of moving object
If the seat holding apparatus is made compact, then the ease of insertion into vehicle body is improved, but the adaptability to various seat specifications may be reduced
Solution Approach 1:
The clamp unit is designed to be inserted into the space between the seat cushion and seat back, effectively nesting the gripping mechanism within the seat structure itself. This nesting approach minimizes the external volume of the apparatus while maintaining full functionality for holding various seat types
Solution Approach 2:
The apparatus utilizes vertical space by positioning the clamp unit between the cushion and backrest, and employing vertically movable cushion push units. This three-dimensional arrangement allows the compact apparatus to achieve full adaptability across different seat specifications without requiring excessive horizontal space
3Ease of operation
If the clamp is inserted between seat cushion and seat back, then the ease of operation is improved, but the risk of interference with vehicle body holes increases
Solution Approach 1:
The apparatus is designed with predetermined clearance and positioning features that prevent the clamp and push units from contacting vehicle body holes during the seat insertion process. The compact configuration and controlled movement paths are planned in advance to avoid interference, allowing easy operation without creating harmful interactions with the vehicle body structure
