Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum cleaners have complex structures and high manufacturing costs due to the configuration of electronic control units with multiple contacts, complicating assembly and increasing production expenses.
Innovation Solution
A vacuum cleaner design with an electronic control unit featuring a single electronic card with both activation contacts, allowing for simplified assembly and reduced manufacturing costs, while maintaining the ability to switch between normal and reinforced suction modes with intuitive and ergonomic operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple electronic cards with separate contacts are used to control different operating modes, then the control functionality is achieved, but the device complexity and manufacturing costs increase
Solution Approach 1:
The patent combines multiple separate electronic cards with individual contacts into a single integrated electronic card containing all necessary contacts. This merging approach maintains the full control functionality for different operating modes while significantly reducing device complexity, assembly steps, and manufacturing costs.
Solution Approach 2:
The single electronic card is designed to perform multiple functions by incorporating all contact arrangements needed for different operating modes (normal mode, reinforced mode, pulse mode) on one card, making it a universal control component that replaces multiple specialized cards.
2Adaptability or versatility
If multiple electronic cards with separate contacts are used, then the control functionality is achieved, but the assembly process becomes more complex and time-consuming
Solution Approach 1:
By merging all contact arrangements onto a single electronic card, the patent reduces the number of assembly operations required. The single card can be installed in one operation rather than requiring multiple separate cards to be positioned and connected, thereby simplifying the assembly process and reducing manufacturing time.
3Adaptability or versatility
If multiple electronic cards are used, then the control functionality is achieved, but the manufacturing costs significantly increase
Solution Approach 1:
The consolidation of multiple electronic cards into one reduces material costs, manufacturing overhead, and quality control expenses. The single card approach eliminates the need to produce, test, and manage multiple separate components, leading to significant reductions in overall manufacturing costs while preserving all control functionalities.
4Ease of operation
If the activation organ is positioned remotely from the control body, then the user can easily access it, but the device structure becomes more complex
Solution Approach 1:
The single electronic card serves as a universal interface that receives signals from both the control body and the remotely positioned activation organ. This multi-functional design allows the system to accommodate the remote activation organ for user convenience without adding structural complexity, as the same card handles all control inputs.
