Adjustable Stock Assembly for Fluid Spray Gun Ergonomics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators of high-pressure fluid spray guns face discomfort due to the inability to adjust the stock assembly for a comfortable operating position, limiting ergonomic efficiency during use.
Innovation Solution
An adjustable stock assembly with a flexible body rest pad arrangement that can change shape, rotate, tilt, and adjust in length to accommodate different operator sizes and preferences, featuring a pad shape adjustment system and linkage mechanism for customizable positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the stock assembly is made fixed and non-adjustable, then the device complexity is reduced, but the operator comfort and ergonomic efficiency deteriorate
Solution Approach 1:
The stock assembly is transformed from a fixed structure to a dynamic, adjustable one. The pad arrangement can be repositioned along the stock assembly's length and rotated to different angles, allowing it to adapt to various operator preferences and body types while maintaining a relatively simple overall structure.
Solution Approach 2:
The stock assembly is divided into separable components: the pad arrangement and the stock assembly body. The pad arrangement can be independently adjusted and repositioned, allowing for customization without requiring complete redesign of the entire stock assembly structure.
2Adaptability or versatility
If the pad arrangement is made adjustable with multiple degrees of freedom, then the adaptability to different operators is improved, but the device complexity increases
Solution Approach 1:
The stock assembly is designed to serve multiple functions: it provides structural support, accommodates pad positioning adjustments along its length, and allows rotational angle adjustments. This multi-functionality is achieved within a unified structure rather than through multiple separate mechanisms.
Solution Approach 2:
The pad arrangement transitions from a fixed position to a dynamically adjustable one, capable of moving along the stock assembly and rotating to various angles. This dynamic capability allows a single device to adapt to multiple operator configurations without requiring multiple specialized components.

AI summary
An adjustable stock assembly for a fluid spray gun can be adjusted to have a different profile shape; and/or to have a different rotational position relative to the rest of the spray gun; and/or to have a different length relative to the rest of the spray gun; and/or to have a different tilt angle relative to the rest of the spray gun.
