Amusement Ride Seat With Dynamic Restraints for Free-Shoulder Posture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing amusement apparatus seats immobilize users too rigidly, limiting the ability to adopt new positions and diminish the ride sensation, failing to provide the desired excitement and variety in user experiences.
Innovation Solution
A seat design for amusement apparatus featuring a support structure that allows riders to sit astride, with a movable arm and retractable leg extensions, enabling a forward leaning posture and crouched motorcycle riding position, while maintaining security through adjustable restraints and actuators, allowing shoulders to remain free.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed back and fork hinged on the back are used to immobilize the user, then safety is ensured, but the user cannot make movements of any kind, diminishing the ride sensation
Solution Approach 1:
The seat employs dynamic restraint mechanisms including a movable fork that transitions from a raised unrestrictive position to a lowered immobilizing position, and a backrest with adjustable inclination angles (0°, 15°, 30°, 45°) that can adapt to different user preferences and ride conditions, allowing the system to balance safety and movement freedom
2Reliability
If the user is firmly held in the seat against movements, then safety is improved, but the ride sensation and excitement are reduced
Solution Approach 1:
The restraint system operates periodically, transitioning between restrictive and non-restrictive states. The fork lowers to immobilize the user during high-risk phases of the ride and raises to allow movement during safer phases, creating a rhythmic pattern of constraint and freedom that maintains both safety and ride enjoyment
3Reliability
If traditional immobilizing restraints are used, then user security is maintained, but new positions and attitudes cannot be adopted
Solution Approach 1:
The backrest incorporates dynamic adjustability with multiple fixed inclination positions (0°, 15°, 30°, 45°) and the capability for continuous adjustment within ranges, allowing users to adopt various seating attitudes and positions while maintaining security through the adaptable restraint system
Solution Approach 2:
The restraint system is segmented into independent adjustable components including the fork, backrest, and leg rests, each capable of independent positioning to accommodate different user body types and preferred postures while maintaining overall security
4Reliability
If the fork is lowered to immobilize the user's shoulders and chest, then safety is ensured, but all user movements are prevented
Solution Approach 1:
The fork operates periodically, lowering to immobilize the user's shoulders and chest during critical safety phases and raising to permit movement during less critical phases, creating a temporal separation between safety constraint and movement freedom
Solution Approach 2:
The fork is designed as a dynamic component that can transition between raised and lowered positions, and the backrest can adjust its inclination angle, allowing the system to adapt the degree of immobilization based on ride conditions and user needs

AI summary
A seat for amusement apparatus including a support and means for immobilizing the user on the support. The immobilizing means comprise at least one support in front of the user and opposing means suitable for acting on the user's back. The opposing means comprises an arm which can move between a lowered position in which the user can sit down on the support and a raised position in which one end of the arm abuts against the user's back. The seat may optionally have a motorcycle shape and include handlebars and retractable leg extensions projecting from each side of the seat for maintaining a user's legs in a crouched motorcycle riding position.
