Solution Overview

Problem

Existing inclination-adjustable seats have limited adjustable ranges and inconvenient control mechanisms, with complex structures and small adjustable angles due to the need for simultaneous adjustment of multiple knobs.

Innovation Solution

An adjustment mechanism comprising a connecting tube, a supporting rod with positioning holes, an adjusting member with a channel and elastic element, and a fastening element, allowing for telescopic adjustment and rotation to change the inclination of the seat within a range of 35 to 55 degrees.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a complex adjusting device with grooves and multiple knobs is used, then the inclination can be adjusted, but the structure becomes complicated and the adjustable range is limited

Engineering Contradiction:

Improveadjustable range of inclinationVSAvoidstructure complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The adjusting device is segmented into a connecting tube with receiving holes and a supporting rod with positioning holes. This segmentation allows for a simpler structure while maintaining multiple adjustment positions, resolving the contradiction between complexity and adjustability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The supporting rod is nested within the connecting tube, with the rod telescoping inside the tube. This nesting arrangement simplifies the overall structure by eliminating the need for separate adjustment mechanisms, while still providing multiple inclination positions through the hole-aligning system.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Adaptability or versatility

If multiple knobs must be simultaneously adjusted, then the inclination can be changed, but the operation becomes inconvenient

Engineering Contradiction:

Improveinclination adjustment capabilityVSAvoidconvenience of control

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

Multiple adjustment functions are merged into a single supporting rod that telescopes within the connecting tube. By aligning one positioning hole with one receiving hole, both sides of the seat are adjusted simultaneously, eliminating the need to coordinate multiple knobs and greatly improving operational convenience.

Inventive Principle:

Principle #5Merging (Combining)
