Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing machine-washable temperature controllers face issues with structural complexity and poor durability of the sealing effect for incoming and outgoing power supply lines due to the use of silicone material, which is prone to breaking under machine washing forces.
Innovation Solution
A design structure featuring a silicone shell with a concave cavity, a PCBA board, a silicone support plate, and a webbing-type electronic wire with a gum dipping portion, using silicone with specific viscosities for encapsulation to form a one-piece, rugged, and sealed structure that enhances waterproofing and mechanical strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If insulating sleeves for incoming and outgoing lines are made of silicone material to achieve better sealing effect, then sealing effect is improved, but wear resistance deteriorates and the lines are easy to break during machine washing
Solution Approach 1:
The patent uses composite materials by combining silicone insulating sleeves with wire armor protection. The silicone material provides sealing effect while the wire armor layer provides mechanical strength and wear resistance, resolving the contradiction between sealing and durability during machine washing
2Strength
If insulating sleeves are made shorter to avoid durability issues, then wear resistance is improved, but structural complexity increases due to need for wiring structures and multiple connections
Solution Approach 1:
The patent merges the insulating sleeve function with the wire armor protection into a single integrated structure. This combination eliminates the need for separate wiring structures and multiple connections, reducing device complexity while maintaining durability through the reinforced wire armor design

AI summary
The present disclosure provides a design structure of a machine-washable temperature controller, to highly integrate a waterproof design and improve structure stability. The design includes a temperature controller body. The temperature controller body includes a silicone shell having a concave cavity. A PCBA board is disposed in the concave cavity of the silicone shell. The design is unique in that a silicone support plate without a retaining wall board and a webbing-type electronic wire are provided. Strengthening and waterproofing of the overall structure are implemented through silicone with a specific viscosity. The webbing-type electronic wire is connected through a wiring slot notch, and a key portion is processed through a gum dipping technology, to enhance waterproof effect. After silicone for surface waterproof encapsulation is cooled, the overall structure becomes a rugged and sealed one-piece structure. This ensures stability and reliability in a laundry process, and provides an efficient and reliable solution for temperature control in a machine laundry environment of heating clothes. In this innovative technology, the PCBA board has better sealing effect and better effect on resistance to machine washing torque without a wiring structure, showing a broad application prospect.
