Seat Hose Mounting Bracket for Reliable Weight Sensor Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for routing and securing flexible hoses in seat assemblies, such as those connecting weight sensors to pressure sensors, often result in hoses being damaged, kinked, or twisted due to improper positioning and lack of secure attachment, which can affect the accuracy of weight detection and airbag deployment systems.
Innovation Solution
A mounting bracket with specific attachment features, including clips and clamps, is designed to securely engage both the seat frame and the flexible hose, ensuring proper routing and preventing damage by allowing only one correct positioning and securing the hose through a combination of resilient tabs, hooks, and self-threading screws.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple clamps are used to attach the hose to the seat frame, then the hose movement is limited and positioning is improved, but the device complexity and installation difficulty increase
Solution Approach 1:
The patent combines multiple clamps into a single integrated mounting bracket assembly. The bracket includes a base portion that attaches to the seat frame and multiple clamp portions that secure the hose at different locations simultaneously. This merging of multiple separate clamps into one unified structure reduces installation complexity while maintaining reliable hose positioning through multiple attachment points.
2Ease of operation
If the hose is allowed to move freely relative to the seat, then installation is easier, but the hose may be damaged, kinked, or twisted during installation and use
Solution Approach 1:
The mounting bracket is pre-configured with clamp portions positioned at optimal locations along the hose length. During installation, the hose is simply placed into the pre-positioned clamps which automatically secure it in the correct position. This preliminary arrangement of attachment features guides the installer through proper hose routing without requiring complex positioning steps, while simultaneously protecting the hose from damage by preventing sharp bends or twisting.
3Device complexity
If a single mounting bracket is used to attach multiple clamps, then the device complexity is reduced, but the manufacturing precision requirements increase
Solution Approach 1:
The mounting bracket is designed as a universal component that performs multiple functions: it attaches to the seat frame via mounting features, secures the hose at multiple locations through integrated clamp portions, and provides structural support. By consolidating these functions into a single multi-functional part, the patent reduces the total number of components while the precision requirements are managed through standardized manufacturing processes for the bracket's geometric features.
