Solution Overview
Problem
Existing household appliances for laundry care face challenges in securely and efficiently holding heating elements, which affects their functionality and ease of assembly/disassembly.
Innovation Solution
A holder with a base base and a retaining clip provides a detachable and stable mechanism for holding the heating element, allowing for improved support and easy assembly/disassembly through a mechanical connection, enabling precise positioning and secure fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a detachable connection is used to hold the heating element, then ease of assembly and disassembly is improved, but holding stability and precision are worsened
Solution Approach 1:
The holder is divided into two separate components: a base that remains attached to the appliance and a retaining clip that can be detached. This segmentation allows the base to provide stable mounting while the retaining clip enables easy attachment and detachment of the heating element, resolving the contradiction between stability and ease of operation.
Solution Approach 2:
The retaining clip is designed with elastic properties, allowing it to dynamically adjust during attachment and detachment. The elastic deformation of the clip provides a simple yet reliable mechanism for securing the heating element while maintaining ease of operation, as the elastic force automatically ensures proper engagement without requiring complex fastening mechanisms.
2Reliability
If a bulky and heavy bracket is used to support the heating element, then holding stability is improved, but device weight and space consumption are worsened
Solution Approach 1:
By separating the holder into a base and a retaining clip, each component can be optimized for its specific function. The base can be lightweight since it only needs to provide mounting structure, while the retaining clip uses elastic deformation to provide the necessary holding force, eliminating the need for a heavy, bulky bracket.
Solution Approach 2:
The retaining clip is designed as a thin, elastic component that uses flexibility to provide secure holding. This flexible design replaces the need for thick, heavy rigid structures, significantly reducing the overall weight and space consumption of the mounting system while maintaining holding stability.
3Device complexity
If a simple mounting structure is used, then device complexity is reduced, but positioning precision is worsened
Solution Approach 1:
The segmentation into base and retaining clip allows the simple base to provide overall positioning while the retaining clip, through its elastic deformation and specific geometry, provides precise positioning of the heating element. This division enables achieving positioning precision without complicating the overall mounting structure.
Solution Approach 2:
The retaining clip utilizes changes in elastic parameters (deformation, force) to achieve precise positioning. By carefully designing the elastic properties and geometry of the clip, precise positioning of the heating element is achieved through simple elastic deformation rather than complex mechanical adjustment mechanisms.
