Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing extractor hoods require separate electrical and mechanical support lines, which can be visually unattractive and prone to disruption, and do not efficiently distribute power.
Innovation Solution
A combined suspension cable that integrates an electrical conductor and a support member, allowing for a single cable to supply energy and absorb mechanical loads, with options for multiple cables to enhance stability and independent switching of components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If separate electrical supply line and support member are used, then electrical connection and mechanical support are provided, but visual appearance is degraded and the system is more complex
Solution Approach 1:
The patent combines the electrical conductor and mechanical support member into a single integrated cable assembly. The conductor is embedded within the support cable structure, eliminating the need for separate electrical and mechanical lines. This merging reduces the number of components while providing both electrical power transmission and mechanical load-bearing functions through one unified structure.
Solution Approach 2:
The support cable is designed to perform multiple functions simultaneously: it provides mechanical support to hold the extractor hood, transmits electrical power to the hood's components, and offers structural protection for the embedded conductor. This multi-functional design eliminates the need for separate specialized components for each function.
2Reliability
If multiple separate cables are used for power supply, then reliable electrical connection is achieved, but the installation space required increases
Solution Approach 1:
The electrical conductor is nested within the support cable structure, with the conductor embedded inside the cable's internal architecture. This nesting arrangement allows the electrical and mechanical components to occupy the same spatial envelope, significantly reducing the overall space required for installation compared to having separate cables running parallel to each other.
3Ease of manufacture
If conductor member is exposed, then electrical connection is established, but the conductor is vulnerable to mechanical damage
Solution Approach 1:
The conductor is enclosed within a flexible protective cable structure that provides mechanical protection while allowing the conductor to maintain its electrical functionality. The cable's flexible housing protects the embedded conductor from mechanical damage, abrasion, and environmental factors while still permitting electrical connection at the terminals.
