Cover for bench backrests
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current solutions for bench backrest covers lack effective protection and fail to provide a clear advertising space, often creasing or flapping in the wind, and are not designed for easy use or low production costs.
Innovation Solution
A cover designed to be slipped over the backrest of a bench, featuring a longer rear surface connected to a shorter seat-facing surface via side parts, ensuring a snug fit without creases, providing protection and clear advertising visibility, while being easy to use and cost-effective.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cover is made to fit tightly on the backrest, then protection and advertising visibility are improved, but the cover becomes difficult to install and remove
Solution Approach 1:
The cover is made from a flexible textile material that can be stretched and molded to fit the backrest contours, then easily removed and reused. The flexible nature allows the cover to maintain tight contact for protection while being simple to install and remove.
2Loss of information
If the cover material is made smooth and taut, then advertising visibility is improved, but the cover loses comfort for leaning
Solution Approach 1:
The cover employs different surface qualities in different areas: the front surface facing viewers is kept smooth and taut for optimal advertising visibility, while the rear surface contacting users is designed with softer, more compliant characteristics for comfortable leaning. This local differentiation resolves the contradiction between visibility and comfort.
3Ease of manufacture
If the cover is designed as a single piece, then production costs are reduced, but the fit and protection effectiveness worsen
Solution Approach 1:
The cover is divided into multiple sections or panels that can be separately manufactured and then assembled. This segmentation allows each part to be optimized for specific functions (protection, comfort, visibility) while maintaining overall integration, achieving both cost-effectiveness and effectiveness.
4Reliability
If the cover sides are made longer, then protection coverage is improved, but the cover creates more creases and folds
Solution Approach 1:
The cover design incorporates curved contours and rounded edges that follow the natural shape of the backrest. This curvature allows the material to drape smoothly without creating sharp creases or folds, while still providing extended coverage for improved protection.

AI summary
The invention relates to a cover for benches. The cover is designed to be pulled over the backrest of a bench, comprising a seat-facing surface and a longer rear surface, the seat-facing and rear surfaces being connected to each other on the left and right by two side panels, and the cover having a substantially planar cut. This cover provides protection for the backrest of a bench and for the occupants from drafts in the kidney and buttocks area, and also generates additional advertising space, for example, on benches in sports halls or on sports fields.
