Demolition Device Support with Adjustable Hinge and Knee Brace
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Demolition devices like jackhammers are tiring to use due to their weight and vibration, and operators often must work in non-ergonomic positions, leading to potential injuries and safety concerns, with existing support solutions not adequately addressing ergonomic issues, especially in tight spaces.
Innovation Solution
A demolition device support with an elongated rigid body featuring a base frame, upper support member, and handlebar, allowing for adjustable angles and a knee brace for ergonomic positioning, which enables users to apply force efficiently and maneuver the device in tight spaces without wheels, reducing strain and improving safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If wheeled trolleys are used to support demolition devices, then the weight support problem is addressed, but the device becomes difficult or impossible to use in close quarters
Solution Approach 1:
The invention removes the wheeled base from the support system, extracting the mobility function from the support structure itself. The support device becomes a portable, wheelless structure that can be manually positioned into tight spaces without the bulk and complexity of wheels, directly resolving the contradiction between weight support and maneuverability in close quarters
Solution Approach 2:
Instead of making the support device self-moving through wheels, the invention inverts the approach by making it manually positionable. The operator directly controls positioning by carrying and placing the support device where needed, transforming the mobility paradigm from autonomous (wheeled) to manual, enabling access to confined areas
2Ease of operation
If operators use demolition devices directly, then full control and maneuverability are maintained, but the operator must work in non-ergonomic positions leading to injury
Solution Approach 1:
The support device serves as an intermediary between the operator and the demolition device. It absorbs the weight and vibration, allowing the operator to control the demolition device from a comfortable, upright position rather than bending over to support it directly, thereby eliminating ergonomic injuries while maintaining full control
Solution Approach 2:
The support device structure, particularly the base frame and support members, acts as a counterweight system that bears the demolition device's weight and stabilizes it during operation. This transfers the gravitational load from the operator's body to the support structure, preventing musculoskeletal strain
3Weight of moving object
If traditional supports are used, then weight support is provided, but the operator remains in a non-ergonomic position
Solution Approach 1:
The support device introduces vertical dimensionality to the operation. By elevating the demolition device on an extended support structure with vertical members and positioning it at optimal height, the operator can work from an upright position rather than bending forward, transforming the ergonomic dimension from horizontal strain to vertical support

AI summary
A demolition device support has an elongated body that includes a base frame, a base frame support member, and an upper support member. The base frame is fixedly attached to the base frame support member, which is pivotably connected to the upper support member by a hinge. A handle extension member is mounted at the upper end of the body, and includes a mount for receiving handlebar. A collar is mounted at the lower end of the body, and is configured to receive a portion of the housing of a demolition device. The demolition device support is used to support a demolition device in an ergonomic and efficient position during use of the demolition device.
