Toy Launcher Projectile Checking Housing Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing toy launchers lack effective safety features to prevent the insertion of inappropriate objects and ensure operation only with predetermined, appropriately sized projectiles, leading to potential bodily injury and property damage.
Innovation Solution
A toy launch apparatus with an improvised projectile checking housing assembly that includes a step structure and locking mechanism, preventing operation unless an appropriately sized projectile with corresponding features is inserted, utilizing a movable button and catch latch system to ensure proper alignment and size verification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple improvised projectile checking and locking methods are implemented, then safety and reliability are improved, but device complexity increases
Solution Approach 1:
The projectile checking system is divided into multiple independent checking mechanisms: a first checking mechanism that verifies projectile presence and a second checking mechanism that verifies projectile specifications. Each mechanism operates independently through its own sensor and locking control, allowing the system to achieve high reliability through modular redundancy without requiring a single complex checking system.
2Manufacturing precision
If a projectile receiving opening with step structure is provided, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The projectile receiving opening is pre-formed with a step structure during manufacturing that automatically guides and positions projectiles of correct specifications. This preliminary structural preparation ensures that only properly sized projectiles can be inserted and retained, achieving precise projectile verification through a simple geometric feature rather than complex active checking mechanisms.
3Reliability
If multiple checking mechanisms with separate locking controls are used, then reliability is improved, but ease of operation deteriorates
Solution Approach 1:
Although there are two independent checking mechanisms with separate locking controls, both locking controls are integrated into a single trigger assembly. The trigger mechanism must simultaneously satisfy both locking control requirements to discharge, merging the operation of multiple safety checks into one unified user action. This maintains ease of operation by requiring only a single trigger pull while ensuring both checking mechanisms are satisfied.
