Combination Stud-Panel Fastener for Simplified Tube Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening techniques require two different fasteners to secure objects to vehicular components with either studs or panel openings, which increases inventory complexity and assembly time.
Innovation Solution
A combination fastener that includes a carrier portion for securing tubes and a fastener portion with both stud-retention and panel-retention features, allowing it to engage either a stud or a panel opening, thereby simplifying the fastening process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If two different fasteners (stud fastener and panel fastener) are used to address studs and openings respectively, then the fastening function is reliable, but the inventory complexity increases and assembly time is extended
Solution Approach 1:
The patent combines stud fastener features and panel fastener features into a single combination fastener body. The fastener includes both a stud engagement feature (with resilient arms that deflect outward to engage studs) and a panel engagement feature (with resilient arms that deflect inward to engage panel openings), eliminating the need to stock two separate fastener types while maintaining reliable fastening functionality for both stud and panel applications
Solution Approach 2:
The combination fastener is designed as a universal fastener that can perform multiple functions: it can engage with studs using its stud engagement feature and with panel openings using its panel engagement feature. This multi-functionality allows a single fastener design to replace two previously required fastener types, reducing inventory complexity while preserving fastening reliability
2Reliability
If two different fasteners are used to address studs and openings respectively, then the fastening function is reliable, but the assembly time increases
Solution Approach 1:
By merging stud and panel fastener capabilities into one combination fastener, the assembly process is simplified. Assemblers no longer need to identify and select between two different fastener types, reducing decision time and potential errors. The single fastener design maintains reliable engagement with both studs and panel openings while streamlining the assembly workflow
Solution Approach 2:
The universal combination fastener eliminates the need for multiple fastener inventories and selection processes during assembly. Whether the application requires stud engagement or panel opening engagement, the same fastener design is used, reducing assembly time through simplified part selection and handling while maintaining the reliability of the fastening function

AI summary
Described is a combination fastener for attaching an object to a stud extending from or an opening formed in a component. The combination fastener includes a carrier portion to retain the object and a fastener portion. The fastener portion includes a body sidewall that defines a central longitudinal axis and a hollow space configured to receive the stud. A plurality of stud-retention features are resiliently coupled to an interior surface of the body sidewall to retain the stud within the hollow space. Each of the plurality of stud-retention features are angled toward the central longitudinal axis to deflect outward from the central longitudinal axis as the stud passes through the hollow space. A plurality of panel-retention features resiliently coupled to an exterior surface of the body sidewall to retain the combination fastener within the opening.
