Ventilating device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ventilating devices are inflexible and costly due to their inability to add or alter functions after sale, and the lengthening of lead wires to accommodate additional functional units disrupts airflow and increases costs.
Innovation Solution
A ventilating device design featuring a modular structure with a mounting base and circuit board system that allows for easy assembly and disassembly of functional units, reducing lead wire length and enabling convenient function additions or changes without compromising airflow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If various functional units are mounted on the ventilating device, then the functionality of the device is enhanced, but the lead wire length increases and cost increases
Solution Approach 1:
The patent combines multiple functional units (sensor unit, control unit, communication unit) onto a single circuit board that is integrated into the main body shell. This merging approach eliminates the need for separate lead wires for each functional unit, reducing overall wiring length and cost while maintaining enhanced functionality.
Solution Approach 2:
The circuit board serves as a universal platform that can accommodate multiple different functional units. By designing the circuit board with universal connectivity and the main body shell with integrated mounting capabilities, the system achieves multi-functionality without requiring additional lead wires for each added function.
2Adaptability or versatility
If various functional units are mounted on the ventilating device, then the functionality of the device is enhanced, but the device cost increases
Solution Approach 1:
The patent merges multiple functional units onto a single circuit board that is integrated into the main body shell. This consolidation reduces the total number of components, simplifies assembly procedures, and lowers manufacturing costs while still providing enhanced functionality through the integrated design.
Solution Approach 2:
The universal circuit board design allows the same base structure to support multiple different functional configurations. This universality reduces per-unit costs by using standardized components and assembly processes across different functional variants, making enhanced functionality more cost-effective.
3Ease of operation
If lead wires are lengthened to accommodate functional units, then the functional units can be positioned away from the air inlet, but the airflow path is disrupted and cost increases
Solution Approach 1:
The patent merges the functional units directly onto the circuit board that is integrated into the main body shell, positioning them away from the air inlet without requiring long lead wires. This integration allows functional units to be optimally positioned for operation while maintaining clear airflow paths and avoiding the harmful effects of extended wiring.

AI summary
A ventilating device includes a rectangular frame, a louver, an adapter, a helix shell and a circuit board box. A mounting base at a bottom surface of the helix shell is configured for installation of a plurality of functional units thereon. The mounting base is provided with a base circuit board for interfacing with the functional units, and the circuit board box is coupled to the mounting base by a lead wire. Both the circuit board box and the mounting base include a hole, through which the lead wire passes. These holes are arranged in a linear manner in an up-down direction arranged at the side towards an air outlet. The plurality of functional units are configured to be freely assembled or disassembled individually to or from the mounting base.
