Back Scratcher Wall Mounting with Spring-Loaded Flex Mechanisms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing back scratching devices either cause damage to walls with permanent fasteners, are not portable, or are ineffective on textured surfaces due to reliance on suction cups, lacking a secure and damage-free, hands-free solution for various locations.
Innovation Solution
A back scratching device with a frame body and abrasive contact surface, featuring flex mechanisms that can be removed and securely attached to a wall surface using pressure-absorbing pads, allowing for adjustable mounting without damaging the wall and enabling use on different surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If permanent fasteners such as screws or adhesive strips are used to attach the back scratching device to the wall, then the device can be securely mounted, but the wall surface is damaged and the device is not easily portable
Solution Approach 1:
The patent changes the mounting mechanism from permanent fasteners to a reversible pressure-based system. The spring mechanism applies variable pressure to clamp the device against the wall, allowing secure mounting without damage. The pressure can be adjusted by compressing the spring further, and the mounting can be easily released by overcoming the spring force, enabling portability while maintaining security.
Solution Approach 2:
The patent replaces the traditional mechanical fastening system (screws, adhesive) with a spring-based clamping mechanism. This mechanical substitution allows the device to be mounted securely through elastic force rather than permanent attachment, eliminating wall damage while maintaining mounting reliability.
2Object-affected harmful factors
If suction cups are used to attach the back scratching device to the wall, then the device is portable and does not damage the wall, but the device is only effective on very smooth surfaces and is easily removed during use
Solution Approach 1:
The patent employs a dynamic spring mechanism that can adapt to different wall surfaces. The spring allows for movement and adjustment, enabling the device to maintain contact pressure on textured surfaces where suction cups fail. The elastic nature of the spring provides continuous pressure adjustment, ensuring reliable mounting on various surface types while remaining portable and non-damaging.
3Adaptability or versatility
If the back scratching device is designed to be easily removable and portable, then the device can be used in various locations, but the mounting security and reliability are reduced
Solution Approach 1:
The patent segments the mounting function into a separate spring-based clamping mechanism that is distinct from the device body. This segmentation allows the mounting system to be optimized for both portability and security independently. The spring mechanism can be easily engaged and disengaged for portability while providing sufficient clamping force for secure mounting, achieving both location flexibility and mounting reliability.

AI summary
A back scratching device is disclosed including a frame body and a back scratching pad. The frame body is operable to be removeably mounted to a wall surface and includes a base having a first end and a second end, a first flex mechanism attached to the first end of the base, the first flex mechanism operable to be flexed outward from the first end of the base from a resting position to a wall clearing position, and a second flex mechanism attached to the second end of the base, the second flex mechanism operable to be flexed outward from the second end of the base from a resting position to a wall clearing position. The first and second flex mechanisms are each operable to move from the wall clearing position to a clutching position for mounting the frame body to the wall surface. The back scratching pad is attached to the base of the frame body and includes an abrasive contact surface.
