Solution Overview
Problem
Existing spiral lifters have complex shell piping designs, making them difficult for consumers to assemble and disassemble, and the abutment parts are poorly designed, posing a risk of injury during assembly.
Innovation Solution
A screw lifter design featuring a base with a drive assembly, a lifting assembly with a screw mechanism and lifting pipe, and a recycling assembly with a recycling pipe, all designed to be simpler and safer, with a reduced number of parts to minimize assembly errors and injuries.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the shell piping design is complex, then the lifting function is achieved, but the assembly and disassembly become difficult
Solution Approach 1:
The shell piping is divided into multiple separate pipe sections that can be independently assembled and disassembled. The lifting pipe and recycling pipe are segmented into multiple parts connected by connection structures, allowing consumers to easily assemble and disassemble the device without dealing with a complex integrated structure.
2Ease of operation
If the number of parts is reduced, then the assembly process is simplified, but the lifting function may be compromised
Solution Approach 1:
The lifting mechanism and recycling mechanism are merged into a single integrated structure. The screw mechanism serves dual purposes: it lifts balls through the lifting pipe and enables recycling through the recycling pipe. This combination reduces the number of separate parts while maintaining both lifting and recycling functions.
Solution Approach 2:
The screw mechanism is designed with multi-functionality, serving both as a lifting device and a recycling device. The same rotational mechanism that elevates balls can also facilitate their return through the recycling pipe, reducing part count while preserving functional reliability.
3Object-affected harmful factors
If the abutment part design is poor, then the structure is simpler, but finger injury risk increases
Solution Approach 1:
The abutment parts are designed with rounded edges and smooth surfaces before assembly occurs. The connection structures between pipe sections include protective features that prevent finger pinching during the assembly process, addressing the safety issue before it can manifest during consumer use.
4Reliability
If more parts are used, then the lifting and recycling functions are more complete, but the risk of losing parts increases
Solution Approach 1:
Multiple functional components are merged into integrated assemblies. The screw mechanism combines driving, lifting, and recycling functions in one unit, reducing the number of separate parts that could be lost while maintaining complete functionality.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design enhances stability and longevity, simplifies assembly and disassembly, reduces the risk of lost parts, and ensures safer assembly by preventing finger injuries, thus improving user experience and safety.
Implementation Method 1
the lifting assembly includes a screw mechanism, a lifting pipe and a lifting inlet and a lifting outlet provided in the lifting pipe
Implementation Method 2
When the toy ball enters the recycling pipe through the recycling inlet, the toy ball relying on its own gravity quickly reaches the recycling outlet
