Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a foldable cloth frame structure is designed, then space efficiency is improved, but structural stability deteriorates
Solution Approach 1:
The supporting legs are designed to be movable between extended and retracted positions, allowing the cloth frame to transition between folded and unfolded states. The legs can be extended to provide structural support when needed and retracted to reduce storage volume, resolving the contradiction between space efficiency and structural stability.
Solution Approach 2:
The supporting legs are designed to nest within each other when retracted, with inner legs fitting inside outer legs. This nesting mechanism allows the legs to occupy minimal space during storage while maintaining full structural capability when extended, addressing both volume reduction and stability requirements.
2Ease of manufacture
If glue fixation is used to assemble the cloth frame, then manufacturing simplicity is improved, but environmental friendliness deteriorates
Solution Approach 1:
The cloth frame is divided into modular components (frame body, supporting legs, cover) that can be assembled and disassembled without adhesive. The segmentation allows for mechanical connection methods such as snap-fits, interlocking structures, or tool-free assembly mechanisms, eliminating the need for glue while maintaining manufacturing simplicity.
Solution Approach 2:
An intermediary assembly mechanism is introduced between frame components, such as a positioning structure or connecting element that enables easy assembly without glue. This intermediary component facilitates tool-free or simple tool-based assembly while avoiding environmental pollution from adhesives.
3Reliability
If a complex positioning frame structure is used, then locking reliability is improved, but device complexity deteriorates
Solution Approach 1:
The positioning frame incorporates self-locking features that automatically engage when the supporting legs are extended or positioned. The structure uses its own geometry and elastic deformation to create locking action without requiring additional complex mechanisms, buttons, or tools, thereby maintaining high reliability while minimizing added complexity.
Solution Approach 2:
Complex mechanical locking systems are replaced with simpler elastic or geometric locking mechanisms. For example, elastic bands or spring-loaded elements provide automatic locking force, and geometric interlocking shapes ensure proper positioning without requiring complex adjustment mechanisms.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The structure allows for foldable and three-dimensional support, is environmentally friendly, and meets user needs with a simple operation and convenient utilization.
Implementation Method 1
The elastic band is fixed between the first supporting leg and the second supporting leg. The first supporting leg and the second supporting leg can be folded and stored. The elastic band plays a folding role. As the first supporting leg and the second supporting leg are pulled apart, they can be pulled by means of the elasticity of the elastic band to reset and combine with each other, so that the second supporting leg is clamped in the positioning sleeve, and the first supporting leg and the second supporting leg are fixed in the shape of I.
Implementation Method 2
Loop fasteners are sewn at four corners on an upper inner side of the cloth frame. Protective belts are sewn at four corners that are located on the hard base under the cloth frame. Hook fasteners are arranged on one end of the protective belts and stuck to the four loop fasteners on the upper inner side of the cloth frame.

AI summary
The present utility model discloses a supporting and locking structure for a cloth frame, which pertains to the technical field of articles for daily use. It comprises a hard base, a cloth frame, a positioning frame, supporting structures, a flip cover, and lifting openings. The cloth frame is fixed on the hard base. The positioning frame is fixed at a cloth frame opening of the cloth frame. Four supporting structures are arranged between the hard base and the positioning frame. The flip cover is sewn on one side on the cloth frame. The lifting openings are arranged on left and right ends of the cloth frame. It is featured with reasonable structure design, beautiful appearance, novel and unique shape, simple operation, convenient utilization, and glue-free fixation. As clamping is adopted as the fixing manner, it is not only simple in production process, but also environmentally friendly for consumers to use. As the three-dimensional support is realized through the supporting structures, it is flatter and more stereoscopic when articles are placed therein. As the lifting openings are arranged on the left and right sides of the cloth frame, it is convenient for people to take, which meets consumers' usage needs.
