Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sports bows require separate middle sections for mechanical and ILF connection systems, limiting flexibility and necessitating new purchases when switching between connection types.
Innovation Solution
A connecting device with adaptable receiving sections that can accommodate different connection types, including mechanical and ILF systems, via interchangeable elements and configurations such as bores with threads and U-shaped recesses, allowing for reversible and adjustable attachments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate middle sections are used for mechanical and ILF connection systems, then each connection type can be optimized for its specific geometry, but the user must purchase multiple middle sections to switch between connection types
Solution Approach 1:
The middle section is designed with a universal receiving section that can accommodate both mechanical connection elements (screws, alignment pins) and ILF connection elements (pivot pockets, tiller screws) through interchangeable adapters. This allows a single middle section to perform multiple connection functions, eliminating the need for separate middle sections for different connection types.
Solution Approach 2:
Interchangeable adapter elements serve as intermediaries between the universal receiving section and different limb connection types. These adapters translate between the standardized receiving section geometry and the specific requirements of mechanical or ILF connections, enabling compatibility without requiring multiple specialized middle sections.
2Adaptability or versatility
If a universal receiving section is used to accommodate both mechanical and ILF connections, then flexibility is improved, but the structural complexity of the receiving section increases
Solution Approach 1:
The receiving section is segmented into a universal base structure and interchangeable adapter components. The base structure contains standardized features (bores, mounting surfaces) that remain constant, while specific connection features are separated into removable adapters that can be swapped based on the required connection type, thereby managing complexity through modularity.
Solution Approach 2:
The receiving section transitions from a static, dedicated design to a dynamic, reconfigurable system. Adapters can be inserted or removed to change the receiving section's functionality, allowing the same physical structure to adapt to different connection requirements without permanent modification or increased inherent complexity.
3Ease of operation
If interchangeable elements are used to adapt the receiving section geometry, then ease of switching between connection types is improved, but the assembly and disassembly process requires additional steps
Solution Approach 1:
The adapter elements are pre-configured with specific connection features (threaded bores for mechanical connections, pivot pockets for ILF connections) that match standardized receiving section interfaces. This preliminary preparation allows users to simply swap pre-made adapters rather than assembling complex connection systems from scratch, reducing the time and complexity of switching between connection types.
