Innovation Solution
An energy efficiency testing device for electric ovens featuring a clamping device with a support frame, temperature sensor, electric push rod, and sponge blocks to ensure proper alignment and prevent damage, along with a correction device using rotating plates and connecting ropes to calibrate the oven's position, and an anti-static device to eliminate static electricity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the electric oven is placed close to the testing device to improve testing efficiency, then the testing process is simplified, but the alignment between the oven access port and the detection device becomes inaccurate
Solution Approach 1:
The patent applies preliminary action by using the conveying device to pre-position the electric oven body at a predetermined location before the detection device is inserted. The controlling device activates the conveying device to move the oven to the correct position in advance, ensuring that when the detection device is inserted, the access port is already aligned with the detection port, thereby solving the alignment accuracy problem while maintaining high testing efficiency.
2Measurement precision
If the electric oven is placed far from the testing device to ensure proper alignment, then the alignment accuracy is improved, but the testing process becomes complex and time-consuming
Solution Approach 1:
The patent applies self-service by making the conveying device controllable by the controlling device, which automatically positions the electric oven body without requiring manual intervention. The system serves itself by automatically adjusting the oven position through the conveying device based on signals from the controlling device, thereby maintaining alignment accuracy while simplifying the testing process and reducing the time required for manual positioning.
3Stability of the object's composition
If a rigid clamping device is used to secure the electric oven, then the alignment stability is improved, but the risk of damaging the oven increases
Solution Approach 1:
The patent applies beforehand cushioning by incorporating sponge blocks between the clamping device and the electric oven body. These sponge blocks act as cushioning elements that prevent direct contact and potential damage while still maintaining the necessary clamping force for stable alignment. The sponge blocks are positioned in advance within the clamping device structure, providing continuous protection during the clamping process and thus resolving the contradiction between alignment stability and damage prevention.
4Manufacturing precision
If the clamping force is increased to prevent oven movement, then the alignment precision is improved, but the risk of damaging the oven increases
Solution Approach 1:
The patent applies beforehand cushioning by incorporating sponge blocks between the clamping device and the electric oven body. These sponge blocks act as cushioning elements that prevent direct contact and potential damage while still maintaining the necessary clamping force for stable alignment. The sponge blocks are positioned in advance within the clamping device structure, providing continuous protection during the clamping process and thus resolving the contradiction between alignment precision and damage prevention.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Ensures accurate energy efficiency testing by maintaining proper alignment and preventing damage, while eliminating static electricity interference, thus ensuring reliable and economic testing results.
Implementation Method 1
when the electric push rod is activated, the electric push rod pushes the push plate to move in a direction closer to the electric oven body, and the electric oven body is clamped through the push plate
Implementation Method 2
movement of the push plate in the direction closer to the electric oven body drives the elastic telescopic rod to move in the direction closer to the electric oven body, and movement of the elastic telescopic rod in the direction closer to the electric oven body drives the connecting plate to move in the direction closer to the electric oven body
Implementation Method 3
the sponge blocks are fixedly mounted on a surface of the connecting plate... movement of the connecting plate in direction closer to the electric oven body drives the sponge blocks to move in the direction closer to the electric oven body, where the sponge blocks are in contact with the electric oven body to prevent damage to the electric oven body during clamping
Implementation Method 4
a temperature sensor fixedly mounted at a top of the support frame
