Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional curved handles face challenges in securely assembling the upper cover and lower lid due to limited space and the presence of electrical elements, leading to loose or difficult-to-disassemble designs.
Innovation Solution
A curved handle design featuring a frame with first and second bars, upper and lower buckle sections, and bumps with fixing slots and holes, allowing for secure engagement and snap-lock mechanisms to ensure tight closure without gaps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional fixing slots and fixing holes are used to assemble the upper cover and lower lid, then the assembly can be disassembled, but the curved shape and electrical elements limit the available space resulting in loose or unsecured ends
Solution Approach 1:
The frame is divided into multiple segments including first bar, second bar, and multiple buckle sections (first through fourth buckle sections) that can independently engage with corresponding features on the upper cover and lower lid. This segmentation allows the assembly to achieve secure fixation at multiple points along the curved structure without requiring large continuous spaces.
Solution Approach 2:
The invention transitions from a conventional single-plane fixing slot and hole arrangement to a multi-dimensional buckle system that engages in multiple directions and planes. The buckle sections extend in different orientations to engage with upper and lower covers, effectively utilizing three-dimensional space within the curved handle structure to achieve secure assembly.
2Reliability
If the upper cover and lower lid are glued together to eliminate gaps, then a tight fit is achieved, but the assembly becomes difficult to disassemble
Solution Approach 1:
The assembly system transitions from a static permanent bond (glue) to a dynamic reversible mechanical connection. The buckle sections can be engaged to provide tight fixation during use, and disengaged when disassembly is needed. This dynamic mechanism allows the same structure to provide both tight fit and ease of disassembly at different operational phases.
Solution Approach 2:
The buckle mechanism is designed to be self-locking during normal use, providing automatic tight fixation without requiring additional fastening operations. When disassembly is needed, the same mechanism allows easy release through simple manipulation of the buckle sections, making the system self-sufficient for both assembly and disassembly operations.
3Reliability
If more fasteners are added to secure the curved handle ends, then assembly security improves, but the device complexity and difficulty of assembly increase
Solution Approach 1:
The buckle sections serve multiple functions: they provide mechanical engagement between upper and lower covers, distribute loading across multiple contact points, and enable both assembly and disassembly operations. This multi-functionality allows a single buckle mechanism to achieve end security without requiring multiple separate fastening systems, thereby reducing overall complexity.
