Energized Grid Fence Opening with Insulating Base
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing protective fences require frequent opening and closing for human and vehicle access, leading to inefficiencies and safety risks as they may not be properly secured, allowing wild animals to cross into separated areas.
Innovation Solution
An electrically energized metal grid apparatus with an insulating base, allowing humans and vehicles to pass while delivering an electric shock to animals attempting to cross, featuring pivot joints and detachable sections for easy transport and deployment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a protective fence is equipped with openings for human and vehicle access, then accessibility to the separated area is improved, but the fence becomes vulnerable to animal intrusion when not properly closed
Solution Approach 1:
An electrically energized grid is installed at the base of the fence opening as an intermediary barrier. The grid delivers electric shocks to animals attempting to pass through, serving as a mediator that prevents animal intrusion while allowing human and vehicle passage without requiring manual opening or closing operations.
Solution Approach 2:
The manual mechanical operation of opening and closing fence gates is replaced by an electric field-based deterrent system. Instead of relying on mechanical gate operations that can be forgotten or improperly closed, the system uses electrical stimulation to actively prevent animals from approaching the opening, substituting mechanical control with an automatic electrical barrier.
2Reliability
If the fence is kept closed to maintain protection, then animal intrusion is prevented, but human and vehicle access becomes difficult
Solution Approach 1:
The energized grid acts as an intermediary that allows the fence to remain in a permanently closed state while still permitting legitimate access. Animals are deterred by the electric field before they can reach the fence, while humans and vehicles can pass through the opening without triggering the electrical deterrent, eliminating the need to open the fence for access.
Solution Approach 2:
The electric field is localized to the opening area where it is needed for deterrence, while the rest of the fence maintains its closed protective state. The grid is positioned specifically at the base of the opening and energized only in that local zone, allowing differentiated functionality: full protection along the fence line and selective permeability at the opening.
3Ease of operation
If manual opening and closing of the fence is performed frequently, then accessibility is maintained, but time loss and risk of improper closing increase
Solution Approach 1:
The manual mechanical operation of opening and closing gates is completely replaced by an automatic electrical deterrent system. The fence remains permanently closed, and the energized grid automatically prevents animal approach, eliminating all time associated with manual gate operations and removing the risk of human error in closing the fence.
Solution Approach 2:
The system serves itself by automatically deterring animals through the electric field without requiring human intervention. The grid is energized continuously and actively prevents animal intrusion on its own, making the fence self-protecting and eliminating the need for human operators to manually open, close, or monitor the fence for animal prevention.

AI summary
The invention is directed to an apparatus (10) and a method for preventing animals to enter or leave a separated area through an opening of the separated area. The invention comprises a grid (18) made from metal bars (40, 42), wherein the grid (18) is adapted to be energized and wherein the grid (18) forms an area with an upper side (20a to 20c) and a lower side (22a to 22c), and an electrically insulating material (24) arranged on the lower side (22a to 22c) of the grid (18), wherein the insulating material (24) is arranged to completely separate the grid (18) from a ground at least during horizontal arrangement of the grid (18) on a horizontal ground.
