Solution Overview
Problem
Prior toy guns with automatic barrel rotation for sequential projectile launch are complex and prone to durability issues due to additional moving components and vulnerable joints, which increases the risk of breakdown.
Innovation Solution
A toy gun design featuring a pumping apparatus with a delivery interface and a locking mechanism that aligns with each projectile chamber in sequence, allowing air to be driven into the chambers via a rotating endplate with strategically positioned holes, reducing the complexity of mechanisms and components required for automatic rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If automatic barrel rotation is implemented to align projectile chambers sequentially, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
Instead of rotating the barrel to align projectile chambers with the pump chamber, the invention inverts the approach by keeping the barrel fixed and rotating the pump chamber assembly. This inversion maintains automatic alignment functionality while simplifying the mechanical connection between the rotating and stationary parts, as the pump chamber can be directly coupled to the rotation mechanism without complex barrel joint interfaces.
2Productivity
If automatic barrel rotation mechanisms are added, then the productivity is improved, but the reliability deteriorates
Solution Approach 1:
By inverting which component rotates (pump chamber instead of barrel), the invention reduces the number of rotating joints and interfaces in the barrel assembly. This inversion maintains the productivity benefit of automatic sequential chamber alignment while improving reliability by minimizing vulnerable rotating connections and moving parts in the barrel structure.
3Ease of operation
If the barrel is rotated automatically, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The invention applies inversion by making the pump chamber assembly rotatable rather than the barrel. This allows automatic alignment of projectile chambers with the pump chamber through rotation, improving ease of operation. Simultaneously, it reduces device complexity by eliminating complex rotating barrel mechanisms and their associated joints, as the rotation is concentrated in the pump chamber assembly which has fewer and simpler connections.

This design simplifies the mechanism, reduces the risk of breakdown, and enhances durability by minimizing the number of moving parts and rotation required, while maintaining efficient sequential projectile launching.
Implementation Method 1
a locking mechanism and a trigger, the locking mechanism operable to lock the pump ram in a cocked position against a resilient bias, the trigger operable to unlock the locking mechanism to release the pump ram from the cocked position, thereby allowing the resilient bias to slide the pump ram along the pump axis to drive air along the pump axis into said one of the projectile chambers
