Thin Safety Door Sliding Baffle Structure for Compact Power Holes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional safety door structures for power holes are too thick due to the protrusion of V-shaped supporting shafts, leading to excessive space occupation.
Innovation Solution
A thin safety door design featuring a baffle with front and rear slopes, sliders, and an elastic element that allows the baffle to slide and pivot like a seesaw, with stop hooks and supporting wings to prevent backward movement, reducing overall thickness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a V-shaped supporting shaft protrudes from the slider to provide support, then the supporting strength is improved, but the overall thickness of the safety door structure increases
Solution Approach 1:
The invention transitions from a protruding three-dimensional supporting shaft to a two-dimensional triangular pattern formed by rivets on a flat cover board. This dimensional reduction eliminates the need for thickness while maintaining structural support through the geometric distribution of rivets forming triangular stability patterns.
Solution Approach 2:
The invention extracts the essential supporting function from the protruding shaft and redistributes it through multiple rivets arranged in a triangular pattern. Instead of one prominent supporting element, multiple smaller rivets work together to provide equivalent or superior support while maintaining a flat profile.
2Stability of the object's composition
If the cover board is made thicker to accommodate the V-shaped supporting shaft, then the supporting stability is improved, but the space occupation increases
Solution Approach 1:
The invention achieves stability not through increased thickness (one dimension) but through the two-dimensional triangular arrangement of rivets. The triangular geometry provides inherent structural stability while keeping the cover board thin, thus reducing overall volume.
Solution Approach 2:
The supporting function is segmented into multiple rivets distributed across the cover board in a triangular pattern, rather than relying on a single concentrated shaft. This segmentation distributes the supporting load and enhances stability while maintaining a thin profile.
3Reliability
If a conventional sliding mechanism is used with protruding supporting shafts, then the safety protection function is achieved, but the overall structure becomes too thick for compact installations
Solution Approach 1:
The invention maintains the safety protection function of the sliding mechanism while reducing thickness by replacing protruding three-dimensional shafts with a two-dimensional rivet pattern on a flat cover board, enabling compact installations.
Solution Approach 2:
The invention merges the supporting function into the flat cover board structure itself through the rivet pattern, eliminating the need for separate protruding shafts. This integration maintains safety functionality while reducing overall structural thickness.

Function Achieved in This Case
The design results in a thinner safety door that occupies less space, enhancing installation adaptability while maintaining effective protection against accidental electric shocks.
Implementation Method 1
the elastic element abuts against the baffle, so that an elastic force is applied to the sliders of the baffle for returning to a higher position when located on the slide ways

AI summary
A thin safety door includes a baffle, a supporting frame and an elastic element. The baffle is provided with a front slope and a rear slope. The baffle is provided with a pair of sliders disposed side by side at a position between the front slope and rear slope of the baffle. A pair of slide ways are disposed on the left side and right side of the supporting frame. The baffle spans the supporting frame and the sliders are connected to the slide ways, so that the baffle can slide relative to the supporting frame. The elastic element abuts against the baffle, so that an elastic force is applied to the sliders of the baffle for returning to a higher position when located on the slide ways.
