Multi-Function Tool Bridge Design for Skateboard Fastener Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tools are inefficient for assembling and disassembling simple mechanical devices like skateboards and bicycles due to the need for frequent removal and replacement of various fasteners of different sizes, leading to complexity and potential loss or misplacement.
Innovation Solution
A multi-function tool with interconnected socket bodies and drive tips, featuring a bridge for torque delivery and a compact design with integrated blades for cutting, allowing for easy handling of multiple fastener sizes and types, and a modular design for storage and use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate tools are used for different fastener sizes, then each tool can be specialized for its function, but the overall system complexity increases and tools can be lost or misplaced
Solution Approach 1:
The patent combines multiple socket bodies with different socket sizes (first socket body with first and second sockets, second socket body with third socket) into a single integrated tool assembly connected by bridges. This merging of previously separate tools into one unified device allows users to handle multiple fastener sizes without needing separate tools, thereby reducing tool complexity while maintaining adaptability.
Solution Approach 2:
The multi-function tool is designed with multiple sockets of different sizes and drive tips that can accommodate various fastener types (e.g., kingpin, axle nuts, mounting bolts). This universal design enables a single tool to perform multiple functions that previously required several specialized tools, resolving the contradiction between versatility and complexity.
2Adaptability or versatility
If various fasteners of different sizes are used in skateboard assembly, then the design can accommodate different mechanical requirements, but the assembly process becomes more complex and time-consuming
Solution Approach 1:
The tool is segmented into multiple socket bodies (first socket body, second socket body) connected by bridges, with each socket body containing sockets of specific sizes. This segmentation allows the tool to address different fastener sizes simultaneously while maintaining an organized structure that improves assembly efficiency by eliminating the need to switch between multiple separate tools.
Solution Approach 2:
By merging multiple socket capacities into a single tool assembly, the patent enables users to handle various fastener sizes (kingpin, axle nuts, mounting bolts) without interrupting the assembly process to retrieve different tools, thereby improving productivity while maintaining adaptability to different fastener requirements.
3Volume of moving object
If a compact tool design is used, then storage and handling become easier, but the tool may not accommodate all necessary fastener sizes
Solution Approach 1:
The tool design nests multiple sockets within socket bodies that are connected by bridges, creating a compact hierarchical structure. Different sized sockets are arranged in a space-efficient configuration that allows the tool to accommodate a wide range of fastener sizes while maintaining a compact overall volume for easy storage and handling.
Solution Approach 2:
The patent utilizes three-dimensional spatial arrangement of socket bodies and bridges to maximize the fastener size range within a compact tool volume. By organizing sockets in multiple dimensions and orientations, the tool achieves high adaptability without proportionally increasing its overall size.

AI summary
A multi-function tool. The multi-function tool includes a first socket body having a first sidewall defining a first socket and a second socket, the first socket body being aligned with a first axis. The multi-function tool also includes a second socket body having a second sidewall defining a third socket, the second socket body being aligned with a second axis that is substantially parallel to the first axis. The first socket body is connected to the second socket body by a bridge.
