Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Computer desks typically lack adjustable storage drawers for keyboards, leading to discomfort and muscle strain due to improper arm posture, as users' heights and arm lengths vary.
Innovation Solution
An angle adjustment mechanism for storage drawers, comprising a locker, connector, movable piece, retainer, and adjustment assembly, allowing for adjustable positioning to accommodate users' comfort by rotating the storage drawer to a suitable angle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the storage drawer is fixed at a single angle, then the structure is simple and stable, but users with different heights and arm lengths cannot achieve comfortable posture
Solution Approach 1:
The storage drawer is transformed from a fixed-angle design to a dynamically adjustable one. The adjustment mechanism includes a movable piece with multiple positions, a retainer that can lock at different angles, and an adjustment assembly with a drive member that enables the drawer to be positioned at various angles suitable for different user heights and arm lengths, thereby achieving comfortable posture for diverse users
Solution Approach 2:
The adjustment mechanism is divided into multiple independent components: a locker with locking section, a connector with fitting portion and teeth, a movable piece with connecting and support sections, a retainer with slots and recesses, and an adjustment assembly. This segmentation allows each component to perform its specific function while working together to provide multi-angle adjustment capability
2Ease of operation
If the storage drawer is made adjustable for different angles, then user comfort is improved, but the structure becomes more complex
Solution Approach 1:
The adjustment mechanism is designed to be user-operable without requiring external tools or complex procedures. The drive member can be manually actuated to move the movable piece between positions, and the retainer automatically locks into place at each angle, allowing users to easily adjust the drawer angle to achieve comfortable arm placement while minimizing the need for complex control systems
