Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hair dryers have a large axial length due to the thickness of electronic components and mounting frames, compromising compactness and user experience.
Innovation Solution
A hair dryer design with a main body housing featuring a first outer housing and an inner handle housing, where the distance between axially opposite ends is less than a predetermined distance, allowing for a compact axial length and size, with the PCB board and heater assembly positioned to facilitate efficient airflow and heat dissipation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the axial length of the main body is increased to accommodate the heater assembly and PCB board, then the installation space requirement is met, but the compactness and user experience deteriorate
Solution Approach 1:
The patent applies dimensional transformation by changing the spatial arrangement of components from a linear axial layout to a radial distribution around the first central axis. The heater assembly, PCB board, and mounting frame are positioned at different radial distances and angular positions, allowing all components to fit within a compact axial length while maintaining proper spacing and functionality.
2Volume of moving object
If the thickness of electronic components on the PCB board is reduced, then the axial length requirement is met, but the manufacturing precision and component reliability may deteriorate
Solution Approach 1:
Instead of reducing component thickness in the axial direction, the patent distributes components in radial and angular dimensions. The PCB board is positioned at a specific radial distance from the first central axis, and its thickness is maintained at standard values while still fitting within the compact axial length through optimized radial positioning.
3Productivity
If the heater assembly length is increased to improve heating efficiency, then the heating performance is enhanced, but the axial length of the main body increases
Solution Approach 1:
The heater assembly is arranged radially around the first central axis rather than extending axially. This radial configuration allows the heater to have sufficient length for effective heating while the axial projection remains compact. The mounting frame positions the heater at an optimal radial distance to maximize heating efficiency within the constrained axial space.
