Multi-Fastener Spanner With Magnetic Chassis Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Attaching or detaching large mechanical parts, such as suspension cylinders from truck chassis, is time-consuming, dangerous, and difficult due to the need to manage multiple fasteners, which can be cumbersome and hazardous for workers.
Innovation Solution
A spanner with multiple spaced fastener grips and magnetic attachment members that allows simultaneous gripping and secure attachment of multiple fasteners, enabling efficient and safe attachment or detachment of parts by aligning with the fastener pattern on the chassis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple fasteners are attached or detached sequentially using traditional tools, then each fastener can be securely fastened, but the process becomes time-consuming and labor-intensive
Solution Approach 1:
The patent combines multiple fastener gripping functions into a single spanner tool. The spanner features multiple jaws or gripping surfaces that can simultaneously engage with multiple fasteners (bolts or nuts), allowing a single tool to perform operations that traditionally required multiple separate tools and sequential actions.
Solution Approach 2:
The spanner is divided into multiple independent gripping zones along its length, with each zone capable of engaging a separate fastener. This segmentation allows the tool to handle multiple fasteners simultaneously while maintaining the ability to grip each individual fastener securely.
2Ease of operation
If workers manually manage multiple fasteners during attachment operations, then fasteners can be controlled individually, but worker exposure to hazards increases and safety decreases
Solution Approach 1:
The spanner merges multiple fastener control functions into a single tool that can manage several fasteners at once. This reduces the need for workers to manually handle multiple fasteners separately, thereby minimizing their exposure to hazardous areas and improving safety.
Solution Approach 2:
The spanner acts as an intermediary tool between the worker and the multiple fasteners. Instead of the worker directly manipulating each fastener in potentially dangerous zones, the spanner serves as a mediator that secures multiple fasteners simultaneously, reducing direct worker exposure to hazards.
3Device complexity
If traditional single-fastener tools are used, then simple tool design is maintained, but the complexity of managing multiple fasteners increases
Solution Approach 1:
The spanner incorporates multiple segmented gripping zones along its length, with each zone designed to engage a separate fastener. This segmentation allows the tool to handle multiple fasteners simultaneously while maintaining a relatively simple overall structure that extends the basic spanner form factor.
