Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing claw crane structures in crane game machines are cumbersome for maintenance and replacement due to sealed coils and wrapped connections, leading to inefficiency and increased costs.
Innovation Solution
A claw crane structure with a PC circuit board positioned above the coil, where both ends of the coil are electrically connected to coil contacts, and the terminals of the winding wire are connected to winding wire contacts on the PC circuit board, allowing for easy assembly, maintenance, and replacement without the need for insulating tape.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the coil and winding wire connections are wrapped and sealed with insulating tape, then the coil is protected and concealed, but maintenance and replacement become time-consuming and labor-intensive
Solution Approach 1:
The patent divides the connection structure into separate modular components: the coil, the winding wire, and the insulating tape are distinct elements that can be independently accessed. The insulating tape is positioned to cover only specific connection points rather than sealing the entire coil, allowing technicians to access individual connection points for maintenance without removing the entire tape covering.
Solution Approach 2:
The insulating tape serves as an intermediary element that can be selectively removed and repositioned. It acts as a protective barrier during operation but can be easily manipulated to provide access to connections for maintenance, then repositioned to restore protection. This intermediary approach allows the system to balance protection during operation with accessibility during maintenance.
2Ease of repair
If the insulating tape is removed for maintenance, then access to coil and winding wire connections is enabled, but the tape must be reapplied to reseal and conceal the coil, resulting in unnecessary waste and inefficiency
Solution Approach 1:
The insulating tape is pre-positioned at specific locations where connections are made, rather than being applied after maintenance is needed. This preliminary positioning allows the tape to be easily accessed and repositioned during maintenance without requiring complete removal and reapplication, reducing material waste and time consumption.
Solution Approach 2:
The insulating tape is designed to be reusable through a simple repositioning process rather than single-use. After maintenance, the tape can be recovered by repositioning it to cover the connections again, eliminating the need to discard the tape and reducing material loss.
3Shape
If the coil is sealed and hidden, then the appearance is improved and protection is enhanced, but technicians must remove the tape before performing maintenance
Solution Approach 1:
The insulating tape is applied locally at specific connection points rather than covering the entire coil uniformly. This local application maintains the overall aesthetic appearance of the coil while providing necessary protection at critical points, and allows technicians to quickly access specific connection areas for maintenance without affecting the overall concealed appearance.
