Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional armrest assembly mechanisms are complex, time-consuming, and resource-intensive, leading to increased costs and waste generation due to the need for intricate structures and materials.
Innovation Solution
The armrest features a guiding groove with lateral walls and a support with a restraining plate, along with an engaging member that includes sliders and positioning members, allowing for simple sliding and rotational movements, reducing assembly complexity and material usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a complicated swivel mechanism is mounted between the armrest base and the support to allow swiveling, then the armrest functionality is improved, but the structure becomes more complicated and assembly becomes more time-consuming
Solution Approach 1:
The patent applies the dynamics principle by enabling the armrest base to rotate relative to the support through a simple rotational joint design. Instead of using a complicated swivel mechanism with multiple components, the invention creates a dynamic connection that allows the armrest to swivel freely within a certain range, achieving the desired adaptability while keeping the structure simple and easy to assemble.
2Adaptability or versatility
If additional functions such as rectilinear adjustment are added to the armrest, then the armrest functionality is improved, but the assemblage becomes more complicated and time-consuming
Solution Approach 1:
The patent applies segmentation by dividing the adjustment functions into independent modular components. The armrest base, support, and engagement members are designed as separate modules that can be easily assembled together. The rectilinear adjustment capability is achieved through a simple sliding engagement mechanism between the armrest base and support, allowing quick assembly without complex fastening operations.
Solution Approach 2:
The invention merges multiple functions (swiveling and rectilinear adjustment) into a single integrated connection system between the armrest base and support. By combining these adjustment capabilities into one unified structure with simple engagement members, the patent eliminates the need for separate mechanisms, thereby reducing assembly time and complexity while maintaining full functionality.
3Adaptability or versatility
If complicated assemblage mechanisms are used, then the armrest functionality is improved, but more materials and resources are used, increasing costs and waste treatment requirements
Solution Approach 1:
The patent extracts unnecessary complex components from the armrest assembly and removes them entirely. Instead of using complicated swivel mechanisms and multiple fasteners, the invention employs a simplified connection system with basic engagement members that achieve the same functional outcomes. This extraction of redundant elements reduces material consumption and waste generation while preserving all essential adjustment and swiveling functions.

AI summary
An armrest includes an armrest base having a guiding groove. A support is mounted below the armrest base. The support includes a top end having a restraining plate. An engaging member includes a body having an upper portion. A slider is formed on the upper portion of the body. The slider includes two arms slideably abutting two lateral walls of the guiding groove, allowing relative sliding movement between the slider and the armrest base along the guiding groove. The engaging plate further includes an insertion plate located below the restraining plate. The engaging member can be rotatably received in the compartment of the support. The top end of the support can include an annular portion having a plurality of annularly spaced teeth in the compartment. A groove is formed between two adjacent teeth. A positioning member projects downwardly from the engaging member and is selectively engaged in one of the grooves.
