Appliance Control Panel Mounting to Prevent Carrier Loosening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing household appliances with control panels and carriers connected via claws often experience loosening and detachment due to long-term use or excessive force, leading to ineffective control.
Innovation Solution
A panel with aligned openings and holes, connected by a cylindrical sleeve and nut, along with a shaft and ribs, ensures secure mounting of the carrier, minimizing deformation and preventing unintended detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the carrier and panel are joined by means of claws, then the assembly is simple to manufacture, but the connection loosens and detaches due to long-term usage or excessive force
Solution Approach 1:
The connection system is divided into multiple functional components: a carrier with integrated claws, a panel with corresponding recesses, and a fastening mechanism with a fastener and retaining clip. This segmentation allows each component to perform its specific function optimally while working together as a unified system.
Solution Approach 2:
The fastening mechanism acts as an intermediary between the carrier and panel. The fastener engages with both the carrier recesses and panel features, while the retaining clip secures the fastener in place, creating a reliable intermediate connection that prevents direct detachment.
2Device complexity
If the carrier is directly mounted to the panel, then the structure is simple, but deformation occurs on the panel due to long-term usage of knobs
Solution Approach 1:
The mounting structure is segmented into the carrier, panel, and fastening mechanism. This segmentation allows the carrier to bear the mechanical loads from knob actuation, isolating the panel from direct stress and preventing deformation while maintaining a relatively simple overall structure.
Solution Approach 2:
The fastening mechanism with fastener and retaining clip provides beforehand cushioning by pre-establishing a secure connection that absorbs and distributes mechanical stresses from knob usage, preventing these forces from being transmitted to the panel and causing deformation.
