Strap Adjustment Mechanism for Variable-Size Exhaust Components
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High horsepower aftertreatment system components in exhaust systems have varying sizes due to large tolerance ranges, making it challenging to secure them with traditional mounting mechanisms that are not adjustable.
Innovation Solution
A strap adjustment mechanism comprising a mounting bracket, a strap, a pin, and a fastener support assembly, where the strap attachment member is engagably coupled to the pin through the fastener support assembly, allowing for adjustable securing of exhaust system components by translating and rotating the second member of the fastener support assembly relative to the first member.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional fixed mounting mechanisms are used, then the mounting structure is simple, but it cannot accommodate varying sizes of aftertreatment components due to large tolerance ranges
Solution Approach 1:
The mounting mechanism incorporates adjustable straps with variable length configurations and rotatable fastener support assemblies that can translate along a central axis, allowing the mounting system to dynamically adapt to different component sizes within tolerance ranges rather than being fixed in a single configuration
Solution Approach 2:
The mounting mechanism is designed with universal features including adjustable strap lengths, rotatable fastener supports, and configurable attachment points that can accommodate multiple component sizes and mounting scenarios, making a single mounting system suitable for various aftertreatment components
2Adaptability or versatility
If adjustable mounting mechanisms are implemented, then adaptability to varying component sizes is improved, but the device complexity increases
Solution Approach 1:
The fastener support assembly is divided into separate functional components including the fastener support body, the rotatable fastener mechanism, and the adjustable strap segments, allowing each segment to be optimized independently while working together to provide the required adaptability
Solution Approach 2:
The rotatable fastener support assembly allows dynamic adjustment of the fastener orientation and position, enabling the mounting mechanism to adapt to varying component geometries while maintaining a relatively simple overall structure through modular design

AI summary
A strap adjustment mechanism may include a pin with a pin opening that is insertable into a looped portion of an end of a strap. The strap adjustment mechanism may also include a fastener support assembly that has a first member and a second member. The second member is configured to translate along a central axis relative to the first member in response to rotation of the first member. The first member includes a first opening substantially collinear with the central axis of the second member, and the second member includes a second opening substantially collinear with the central axis of the second member. The strap adjustment mechanism further includes a strap attachment member that is insertable through the first and second openings of the first member and the second member. The strap attachment member is configured to engagably couple to the pin via the pin opening.
