Problem
Conventional target stands are not easily transportable, occupy large storage space, and require complex setup on uneven terrain, lacking a simple and sturdy foldable design that can remain upright without supplemental tools.
Innovation Solution
A collapsible target stand with a base support assembly having rotatable legs, an upright support frame with a locking mechanism, and a detachable target plate, allowing for easy setup, storage, and transportation, featuring a foldable design that remains stable on various ground surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the target stand is designed to be sturdy and steady on rough terrain, then stability is improved, but device complexity increases due to complex setup steps and supplemental tools required
Solution Approach 1:
The target stand is divided into separate modular components including a base assembly with adjustable legs, an upright support frame, and a target plate. Each component can be independently assembled and adjusted, allowing the structure to adapt to uneven terrain while maintaining simple assembly procedures without requiring supplemental tools.
Solution Approach 2:
The base assembly incorporates adjustable legs that can be independently positioned to accommodate rough, uneven, or sloping ground surfaces. This dynamic adjustment capability allows the stand to maintain stability on various terrains while keeping the overall structure simple and easy to set up.
2Volume of moving object
If the support frame is made foldable to reduce storage space, then storage volume is reduced, but reliability decreases due to lack of mechanism to stably remain in upright position
Solution Approach 1:
The locking assembly is pre-configured with a locking member that automatically engages with a locking surface when the support frame is in the upright position. This preliminary arrangement ensures that once the frame is assembled, it automatically secures itself in the stable upright position without requiring additional mechanisms or tools.
Solution Approach 2:
The locking mechanism operates automatically through the interaction between the locking member and locking surface. When the support frame is positioned upright, the locking member naturally engages with the locking surface, providing self-stabilization without requiring external intervention or complex additional mechanisms.
3Ease of operation
If the target stand uses detachable components for easy assembly, then ease of operation is improved, but strength decreases due to connection points between components
Solution Approach 1:
The base assembly and upright support frame are designed to be securely connected through a integrated connection system where the legs of the base assembly connect to the support frame. This merging of components creates strong structural connections while maintaining the ability to detach for assembly and disassembly, balancing ease of operation with structural strength.
