Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing arm rest supports use a fixed structure, then the structure is simple and stable, but the supporting height cannot be adjusted to meet different user needs
Solution Approach 1:
The arm rest support is divided into multiple independent components: a support body and multiple adjustment members. Each adjustment member can be independently positioned at different heights, allowing the support body to be adjusted to various supporting heights. This segmentation enables height adaptability while maintaining structural simplicity through modular design.
Solution Approach 2:
The adjustment members are designed to be movable relative to the support body, transitioning between fixed and movable states. The adjustment members can be moved to different positions and locked in place, providing dynamic adjustability for supporting height while maintaining stability when positioned. This dynamic characteristic resolves the contradiction between adaptability and structural simplicity.
2Adaptability or versatility
If adjustment members have non-identical cross-sectional dimensions, then multiple supporting heights are achieved, but the manufacturing precision requirements increase
Solution Approach 1:
The adjustment members are designed with non-identical cross-sectional dimensions, where the length and width of each adjustment member's cross section differ. This asymmetric design allows different surfaces of the adjustment members to be placed flat on the supporting surface, achieving multiple distinct supporting heights. The asymmetric geometry provides inherent height variation without requiring complex precision mechanisms.
Solution Approach 2:
The invention utilizes the cross-sectional dimensions (length and width) of the adjustment members as an additional dimension for height adjustment. By varying the cross-sectional dimensions and allowing different orientations of adjustment members, the system achieves multiple supporting heights by exploiting dimensional properties rather than requiring complex mechanical adjustment mechanisms, thereby reducing manufacturing precision requirements.

AI summary
An arm rest support with adjustable height, including a support body and adjustment members connected to two sides of the support body respectively; the adjustment members are movable with respect to the support body to achieve different supporting heights of the support body. A cross section of each adjustment member has different length and width. When the adjustment members are moved such that a surface of each adjustment member corresponding to the length of the cross section thereof is placed flat on a supporting surface, an additional supporting height is achieved. When the adjustment members are moved such that a surface of each adjustment member corresponding to the width of the cross section thereof is placed flat on the supporting surface, a further additional supporting height is achieved. Thus, two additional supporting heights are achieved for the arm rest support to meet the demands of different users.
