Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power line mounting structures for intelligent modules in home appliances face issues with stability and ease of mounting/removal, as they either fail to securely hold smaller modules or complicate the process for larger ones, and can cause electromagnetic interference when mounted inside the appliance.
Innovation Solution
A power line design featuring a base with an accommodation cavity and a rotatable cover for the communication module, along with snap-fit grooves and notches for lead wires, allowing for secure and stable mounting without interfering with the appliance's internal components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the intelligent module is mounted inside the home appliance, then the appearance is improved, but electromagnetic interference occurs and reliability deteriorates
Solution Approach 1:
The intelligent module is extracted from the home appliance body and relocated to the power line. The power line serves as an external mounting platform, allowing the module to be positioned away from electromagnetic interference sources while maintaining a clean appliance appearance. This resolves the contradiction by separating the module from both the appliance interior (avoiding interference) and making it externally accessible (maintaining aesthetics).
Solution Approach 2:
The power line acts as an intermediary carrier between the home appliance and the intelligent module. Instead of mounting the module directly inside or outside the appliance, it is mounted on the power line which connects to the appliance. This intermediary position provides electromagnetic shielding from the appliance while maintaining functional connection, thus resolving the appearance versus reliability contradiction.
2Reliability
If the intelligent module is mounted outside the home appliance, then electromagnetic interference is avoided, but the appearance deteriorates
Solution Approach 1:
The intelligent module is extracted from direct mounting on the appliance and relocated to the power line. This extraction allows the module to be positioned externally (avoiding interference) while the power line itself remains part of the appliance's standard configuration, thus not degrading the overall appearance. The module becomes accessible externally without being attached to the appliance body.
3Adaptability or versatility
If a clearance boss with groove structure is used to mount the intelligent module, then the module can be accommodated, but mounting stability deteriorates for small modules and removal becomes difficult for large modules
Solution Approach 1:
The mounting structure transitions from a fixed rigid groove to a dynamic snap-fit mechanism with elastic deformation capability. The mounting portion can elastically deform during installation to accommodate modules of varying sizes, then maintains a stable locked state. This dynamic behavior allows small modules to be securely held while enabling easy removal of larger modules by applying force to trigger the snap-fit release, resolving the stability versus adaptability contradiction.
4Reliability
If the intelligent module is clamped between the power line and clearance boss and fixed by a fixing sleeve, then mounting stability is improved, but device complexity and ease of operation worsen
Solution Approach 1:
The mounting structure is segmented into distinct functional components: a mounting portion with snap-fit groove on the power line, and a corresponding mounting structure on the module. This segmentation allows each component to be optimized independently and simplifies the overall assembly process. The snap-fit groove provides the locking mechanism while the module's mounting structure provides the engagement interface, eliminating the need for separate fixing sleeves and reducing overall complexity while maintaining stability.
