Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Air disinfection machines require special screwdrivers for maintenance, leading to increased costs and poor user experience due to the need for additional tools.
Innovation Solution
A fixing structure for the ultraviolet lamp tube of an air disinfection machine featuring a bracket, lamp post assembly, and catalytic assembly with threaded connections and elastic clamping members, allowing for easy disassembly and assembly without specialized tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If screws are used to fix the protective cover to the bracket, then the fixing strength is improved, but the ease of maintenance deteriorates because special screwdrivers are required
Solution Approach 1:
The fixing structure is divided into two parts: a threaded portion integrated into the bracket and a snap-fit portion on the protective cover. This segmentation allows the cover to be securely fixed during operation while enabling easy removal by simply pulling it off without tools during maintenance.
Solution Approach 2:
The traditional screw-fastening system is replaced with a hybrid system combining threaded connection and elastic snap-fit mechanism. The elastic component provides both secure fixation and easy release, eliminating the need for screwdrivers and special tools during maintenance operations.
2Ease of repair
If special screwdrivers are provided with the air disinfection machine, then the ease of maintenance is improved, but the device complexity and cost increase
Solution Approach 1:
The protective cover incorporates an elastic snap-fit mechanism that enables users to perform maintenance themselves by simply pulling the cover off and on without requiring any special tools or complex assembly procedures, making the system truly tool-free for end users.
Solution Approach 2:
The elastic component is designed as a simple, inexpensive part that can be easily replaced if needed, avoiding the need for complex tooling systems. The focus is on providing a simple mechanical solution rather than a permanent, tool-dependent fastening system.
3Reliability
If screws are used to fix the protective cover, then the reliability of connection is improved, but the loss of time during maintenance increases
Solution Approach 1:
The threaded portion is pre-integrated into the bracket during manufacturing, and the elastic snap-fit structure is pre-formed on the protective cover. This preliminary preparation ensures that during maintenance, users only need to perform the simple action of pulling the cover on or off, significantly reducing maintenance time while maintaining reliable connection during operation.
