Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Utility workers operating boom trucks are at risk of electric shock due to the conductive nature of electrical systems in vehicles, which can transfer high voltage from power lines to the operator through switches, lacking adequate insulation to prevent electrical discharge.
Innovation Solution
The implementation of an insulating switch assembly made from or coated with highly-resistant materials such as fiberglass, silicon, porcelain, glass, or nonconductive polymers, which separates the operator from electrically charged components by creating a gap of insulating material and air space, reducing the likelihood of electric shock.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional electrical switches are used in utility vehicles, then the vehicle can perform electrical operations, but the operator is at risk of electric shock due to conductive materials transferring high voltage
Solution Approach 1:
The patent introduces an insulating linkage made of nonconductive material as an intermediary between the switch actuator and the electrical contactor. This intermediary component transfers the mechanical actuation force while blocking electrical conduction, thereby protecting the operator from electric shock while maintaining switch functionality
Solution Approach 2:
The switch assembly uses composite construction with insulating materials (such as fiberglass-reinforced plastic) combining mechanical strength with electrical insulation properties. This allows the switch housing and linkage to provide both structural support and electrical protection simultaneously
2Reliability
If insulating materials are added to the switch assembly, then operator protection is improved, but the device complexity increases
Solution Approach 1:
The patent merges the insulating function with the structural components of the switch assembly. The housing and linkage serve both mechanical support and electrical insulation functions, eliminating the need for separate insulating components and reducing overall complexity
Solution Approach 2:
The insulating linkage serves multiple functions: it acts as a mechanical force transmitter, provides electrical insulation, and serves as a structural support element. This multi-functionality reduces the number of separate components needed while maintaining protection
