Chair Armrest Mounting Structure for Multi-Support Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current chair armrests are limited in compatibility, as armrest pads can only be assembled with specific types of armrest supports that require fasteners, leading to high production costs due to the need for multiple pad designs.
Innovation Solution
The design incorporates an armrest pad with a mounting slot and a connection body of corresponding shape and thickness, connected by a connecting member with first and second connection portions, allowing assembly with or without fasteners, enabling compatibility with various armrest supports.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the armrest pad is designed with fastening holes for assembly with armrest supports, then the armrest pad can be firmly fixed to the armrest support, but the armrest pad can only be assembled with limited types of armrest supports that have corresponding fasteners
Solution Approach 1:
The armrest pad is designed with a universal mounting structure that includes both fastening holes for traditional fastener-based assembly and a mounting slot with a connection body that can accommodate armrest supports without fasteners. This multi-functional design allows the same armrest pad to be compatible with multiple types of armrest supports, resolving the contradiction between firm fixation and adaptability.
Solution Approach 2:
A connection body is introduced as an intermediary component between the armrest pad and the armrest support. The connection body includes a mounting slot that can receive and secure various types of armrest supports, including those without fasteners. This intermediary structure enables the armrest pad to adapt to different armrest support types while maintaining reliable connection.
2Adaptability or versatility
If manufacturers produce multiple types of armrest pads for different armrest support types, then compatibility with various armrest supports is improved, but production cost increases
Solution Approach 1:
By designing a single armrest pad with universal mounting capabilities (both fastening holes and mounting slot with connection body), manufacturers can use one pad design for multiple armrest support types, eliminating the need to produce multiple specialized pad variants and thereby reducing production costs.
Solution Approach 2:
The mounting structure is segmented into modular components: fastening holes for traditional assembly and a separate mounting slot with connection body for alternative assembly. This segmentation allows the armrest pad to interface with different armrest support types using appropriate mounting methods without requiring entirely different pad designs.
3Adaptability or versatility
If the armrest pad uses a mounting slot with connection body, then compatibility with armrest supports without fasteners is improved, but the assembly structure becomes more complex
Solution Approach 1:
The mounting slot and connection body are integrated as a unified structure within the armrest pad design. The connection body is positioned to extend into the mounting slot, forming a cohesive assembly feature that simplifies the overall structure compared to having separate mounting mechanisms for different support types.

AI summary
A chair armrest is revealed. The chair armrest includes an armrest support, an armrest pad body, a connection body, and a connecting member. The armrest pad body has a mounting slot with an opening facing downward while the mounting slot has a depth and a shape. The connection body is provided with a thickness and a shape which are corresponding to the depth and the shape of the mounting slot. Thus the connection body can be mounted and positioned in the mounting slot. The armrest support and the connection body of are connected by the connecting member. During assembly of the chair armrest, the armrest support is connected to the connection body by the connecting member while the armrest pad body is affixed with the armrest support into one part by the connecting member. Thereby production cost is reduced.
