Solution Overview
Problem
Existing household appliances face challenges in providing a reliable electrical or signal transmission mechanism, particularly in cooking devices where conventional cables are used, which may not ensure consistent contact and efficient energy transfer.
Innovation Solution
A switch with a first terminal member and a second terminal member are designed to complete an electrical transmission circuit, where the first terminal member has a contact part that is resiliently movable, increasing contact surfaces and ensuring reliable contact, and is integrated into a hinge bearing with specific geometric features for secure mounting and electrical insulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional cables are used for electrical transmission in household appliances, then the device complexity is reduced, but the reliability of electrical transmission is insufficient due to inconsistent contact
Solution Approach 1:
The electrical connection is segmented into two separate terminal members: a first terminal member fixed to the body and a second terminal member fixed to the cover. This segmentation allows each terminal to be independently optimized for reliable contact while maintaining overall system simplicity.
Solution Approach 2:
The first terminal member incorporates a resiliently movable contact part that can dynamically adjust its position. This dynamic capability ensures consistent electrical contact by compensating for manufacturing tolerances and wear, thereby improving transmission reliability without adding complex mechanisms.
2Reliability
If the contact part is made resiliently movable to increase contact surfaces, then the electrical transmission reliability is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The contact part's geometric parameters are optimized to achieve resilience with standard manufacturing tolerances. By carefully selecting the thickness, width, and material properties of the contact part, the design achieves reliable contact enhancement without requiring excessive manufacturing precision.
Solution Approach 2:
The terminal members utilize composite construction combining resilient material for the contact part with rigid material for the body. This composite approach allows the contact portion to be flexible and adaptive while maintaining overall structural integrity, reducing the need for high manufacturing precision.
3Reliability
If the first terminal member is fixed to the body and the second terminal member is fixed to the cover, then the electrical transmission circuit reliability is improved, but the device complexity increases
Solution Approach 1:
The first terminal member serves multiple functions: it provides electrical contact, incorporates resilient movement for contact optimization, and integrates with the hinge bearing structure. This multi-functionality reduces the need for separate components, thereby improving reliability without proportionally increasing device complexity.
Solution Approach 2:
The switch components are merged with existing structural elements of the household appliance. The terminal members are integrated into the hinge bearing and cover assembly, eliminating the need for separate switch housings and mounting structures, thus improving reliability while minimizing complexity increase.
