Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional safety shields are used to cover socket holes, then electrical shock prevention is improved, but device complexity increases and manufacturing cost increases
Solution Approach 1:
The safety shield is divided into a sliding block and a frame, where the sliding block can independently move along the frame. This segmentation allows the shield to transition between closed and open states, providing safety protection while maintaining simplicity in structure and ease of manufacture.
2Object-affected harmful factors
If conventional safety shields are used to cover socket holes, then electrical shock prevention is improved, but ease of manufacture decreases
Solution Approach 1:
The safety shield employs a dynamic sliding block that moves along the frame rather than a fixed complex mechanism. The sliding block is urged by a resilient member and guided by inclined surfaces, creating a simple dynamic system that is easy to manufacture and assemble while providing effective safety protection.
3Productivity
If a simple safety shield structure is used, then ease of manufacture and production efficiency are improved, but safety effectiveness may be compromised
Solution Approach 1:
The sliding block features asymmetric inclined surfaces with different slopes. When an object is inserted into only one socket hole, it contacts one inclined surface and cannot overcome the position limiting member, preventing incorrect insertion. This asymmetric design ensures safety reliability while maintaining structural simplicity for efficient production.
Solution Approach 2:
The resilient member acts as an intermediary between the sliding block and the frame, providing the necessary urging force to maintain the sliding block in the closed position. This simple intermediary component ensures reliable safety protection without adding complex mechanisms, allowing for easy manufacture and high production efficiency.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The safety shield assembly effectively prevents electrical shocks, enhances safety, and facilitates efficient large-scale production with a low-cost, versatile design compatible with various power receptacle types.
Implementation Method 1
a resilient member disposed in the frame; wherein when the resilient member is in its initial state, it urges the sliding block to a closed position
Implementation Method 2
the sliding block further includes two inclined surfaces, wherein when an inserted object pushes on only one of the two inclined surfaces, the position limiting member limits a sliding motion of the sliding block
Implementation Method 3
wherein when two inserted objects simultaneously push on the two inclined surfaces, the sliding block is balanced on the balancing support member and slides along the frame

AI summary
A safety shield assembly for a power receptacle and a power receptacle incorporating the same. The safety shield assembly includes a frame and a sliding block and a resilient member disposed in the frame. The frame has multiple openings corresponding to multiple socket holes of the power receptacle, a position limiting member configured to abut the sliding block, and a balancing support member. In its initial state, the resilient member urges the sliding block to a closed position to covers the openings. The sliding block has two inclined surfaces. When an inserted object pushes on only one of the two inclined surfaces, the position limiting member limits the sliding motion of the sliding block; when two inserted objects simultaneously push on both inclined surfaces, the sliding block is balanced on the balancing support member and is able to slides along the frame to expose the openings.
