Innovation Solution
A carrier rack adapter kit featuring a universal auxiliary luggage carrier structure with rod clamping assemblies and fastening bolts that allow for adjustable mounting on different rod sizes and configurations, enabling quick and secure attachment of auxiliary luggage carriers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a basket is fixed to an existing carrier rack, then luggage carrying capability is improved, but the basket is susceptible to deformation due to force imbalances between the bottom of the basket and the side rods
Solution Approach 1:
The patent introduces an auxiliary luggage carrier structure (plate) as an intermediary component mounted above the existing carrier rack. This plate serves as a mediator between the basket and the rack's side rods, distributing forces more evenly across the structure. The plate is secured with multiple fastening bolts that attach to rod clamping assemblies, creating a stable intermediate platform that prevents direct force concentration on the basket bottom, thereby preventing deformation while maintaining luggage carrying capability.
2Reliability
If a battery pack is permanently placed on the transverse rods, then electrical bicycle power supply is secured, but there is a need for additional luggage storage above the battery pack requiring complex mounting solutions
Solution Approach 1:
The rod clamping assembly is designed as a universal mounting mechanism that can accommodate rods of various sizes and configurations. The assembly includes adjustable components that can adapt to different rod diameters and shapes, allowing the same auxiliary luggage carrier structure to be mounted on various carrier rack types. This universality simplifies the mounting solution, eliminating the need for custom-designed brackets for different rack configurations while still providing reliable luggage storage above the battery pack.
3Adaptability or versatility
If a universal auxiliary luggage carrier structure is mounted on carrier racks of various configurations and dimensions, then adaptability is improved, but the mounting process becomes more complex without standardized rod sizes
Solution Approach 1:
The rod clamping assembly incorporates dynamic adjustment mechanisms that allow the mounting structure to adapt to different rod sizes and configurations. The assembly includes movable components such as adjustable fastening bolts and flexible clamping elements that can be tuned to match various rod dimensions. This dynamic capability enables the same auxiliary luggage carrier structure to be universally mounted on different carrier racks without requiring complex custom fabrication, as the mounting system can be quickly adjusted to suit the specific rod geometry encountered.
4Strength
If traditional fastening methods are used to attach luggage carriers to carrier racks, then secure attachment is achieved, but the mounting and detachment process requires significant time and tools
Solution Approach 1:
The auxiliary luggage carrier structure is designed as a segmented, modular system where the plate, rod clamping assemblies, and fastening bolts are separate, interchangeable components. This segmentation allows for quick assembly and disassembly - the rod clamping assemblies can be independently attached to the rack rods, and the plate can be quickly secured with fastening bolts. When detachment is needed, each component can be independently removed without requiring complete disassembly of the entire mounting system, significantly reducing the time and tools required compared to traditional welded or permanently fixed attachment methods.

AI summary
In a carrier rack adapter kit (1) for adapting a luggage carrier rack of a bicycle, a fastening bolt (4) is extending via a first passageway (71) through an auxiliary luggage carrier structure, via a second passageway (72) through a first rod clamping head (11), and via a third passageway (73) through a second rod clamping head (12). In reaction to a tightening action on the fastening bolt, shear forces along first and second inclined outer surface portions of the first and second rod clamping heads are urging the rod clamping heads to move towards one another. The carrier rack adapter kit allows for universal, easy and quick mounting of an auxiliary luggage carrier structure above luggage carrier racks of various configurations and various dimensions.
