Seat Hose Mounting Bracket for Kink-Free 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.
Innovation Solution
A mounting bracket with specific attachment features that engage both the seat frame and the hose, including clips and clamps, to ensure proper routing and secure attachment, preventing movement and damage during installation and use.
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 routing is controlled, but the complexity of installation increases and the risk of hose damage during installation increases
Solution Approach 1:
The patent combines multiple clamps and routing features into a single integrated mounting bracket assembly. The bracket includes multiple clamps positioned at different locations along the hose route, along with routing features that guide the hose through the seat structure. This integration allows the installer to secure the hose at multiple points simultaneously while following the pre-designed safe routing path, reducing installation complexity while maintaining hose positioning stability.
Solution Approach 2:
The mounting bracket is pre-configured with clamps and routing features positioned at optimal locations determined during design. The hose routing path is pre-planned to avoid sharp edges and minimize bends. During installation, the hose is simply placed into the pre-configured bracket structure, which automatically provides proper routing and secure attachment points, eliminating the need for the installer to determine clamp locations and routing paths.
2Ease of operation
If the hose is allowed to move freely relative to the seat frame, then installation is simpler, but the hose may be damaged, kinked, or twisted during installation and use
Solution Approach 1:
The mounting bracket serves as an intermediary structure between the hose and the seat frame. Instead of directly attaching the hose to the frame or allowing it to move freely, the bracket provides a protective interface that guides the hose along a safe path, supports it at appropriate intervals, and prevents contact with sharp edges or components that could cause damage, kinking, or twisting.
Solution Approach 2:
The bracket is pre-configured with routing features and clamps positioned to protect the hose before installation occurs. The design anticipates potential damage points and pre-positiones protective elements, so that during installation the hose is immediately protected rather than exposed to harmful factors.
3Reliability
If clamps are attached at selected locations to control hose routing, then hose damage is prevented, but the installation time and precision requirements increase
Solution Approach 1:
Multiple clamps and routing features are merged into a single mounting bracket assembly that is installed as one unit. This eliminates the need for the installer to separately position and attach multiple individual clamps at different locations, significantly reducing installation time while maintaining the protective function of securing the hose at multiple points along its route.
