High-Pressure Cleaner Control Carrier for Precise Housing Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing high-pressure cleaners face challenges in precisely positioning multiple openings in the housing part relative to operating and control elements connected to the support frame, making it difficult to achieve accurate alignment and operation.
Innovation Solution
A high-pressure cleaner design where the second and third elements are combined into a structural unit, allowing them to be positioned relative to the switch, with a positioning device facilitating alignment through a mandrel and snap connection, enabling easy centering and fixing of these elements within defined openings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple openings are provided in the housing part for operating and control elements, then the functionality of the high-pressure cleaner is improved, but the positioning precision of these openings relative to the control elements deteriorates
Solution Approach 1:
The control elements are segmented into two groups: the switch is fixed directly to the support frame, while the second and third elements are mounted on a separate carrier that can be positioned relative to the housing part. This segmentation allows independent positioning of each group to achieve precise alignment of all openings.
Solution Approach 2:
A carrier is introduced as an intermediary component between the support frame and the housing part. The carrier holds the second and third control elements and can be positioned relative to the housing part using a positioning device, thereby mediating the positioning relationship between multiple openings and their corresponding control elements.
2Stability of the object's composition
If the housing part is fixed to the support frame, then the structural stability is improved, but the ease of positioning openings relative to control elements deteriorates
Solution Approach 1:
The assembly is segmented into three parts: the support frame with the fixed switch, the carrier with movable control elements, and the housing part. The carrier can be independently positioned relative to the housing part before final fixation, enabling easy positioning while maintaining structural stability in the assembled state.
Solution Approach 2:
The carrier is designed to be dynamically positionable relative to the housing part during assembly using the positioning device, allowing easy alignment of openings. Once positioned, the carrier is fixed to maintain stability during operation, thus transitioning from a dynamic positioning state to a stable operational state.
